NVIDIA GPU FOR CS5 / GTS vs GTX
I'm having a new computer built, and the GPU's I'm considering are either an NVIDIA GTS 450 1GB, or GTX 460 1GB.
I'm aware that the GTX cards are typically twice as fast as their "equivalent" GTS cards, and if I was into Gaming, or Video editing, the GTX would be a "no brainer".
My interest, however, is primarily Photo editing in Photoshop, and it's not clear to me weather the faster speed would have any significant advantage in that regard?
If not, I'd rather invest the additional $85 for the GTX card into something more beneficial, such as additional RAM,etc.
Best regards,
Leigh
My own experience is that any card that scores 500 or higher on the benchmark on this site is excellent for Photoshop:
http://www.videocardbenchmark.net/
The cards you have proposed both score hugely more than that, so I would suggest the less expensive model will more than please you.
Given that Photoshop relies upon OpenGL, and OpenGL development by the video card makers is probably more driven by gaming than anything else, a good gaming card will likely be good as well for Photoshop.

Hi Harm,
I hope it is appropriate to reply to this post. It seemed as good as any in this thread. I have read your posts for years and learn't a great deal from you - you seem to have a great deal of experience in this area. I'm having several rather strange issues with CS5, MPE, the GTX480, playback and artefacts which I am trusting you may be able to assist with. I think that this conversation might help others too as it bring together a lot of information. I'm more than happy to provide additional info but here is some basics to get us started. I will be as brief as I can.
The rig: Windows 7 64-Bit, ASUS P5Q Pro, 8GB RAM, Intel Q9650 Core 2 Quad 3.0GHz (OC'd at 3.51 GHz), Gigabyte GTX480 PSU (Core voltage up to 1125mV, Core clock OC'd to 730MHz), Corsair HX 850W PSU, 7TB Enterprise RAID 5 array (avg@700MB/sec W/R), Dell 30" and Dell 2408 for monitoring.
The CPU is watercooled and hums along between 20c - 26c degrees depending on load and the GPU is surprisingly cool even with the two monitors idling at around 60c and about 75c under heavy loads. So all is well and certainly powerful enough for HDV video editing I assume. My drivers are up to date and I have been running between the 257.21 series and 258.69 and 258.96 beta versions and am currently on the latter but am oscillating between them to test what works. All produce the same results. I have used driver sweeper and the usual processes for these tweaks.
I have been using CS4 for around a year editing HDV for documentary and corporate work and was previously using an 8800GTS @ stock clocks with a lesser 650W PSU. Playback was always smooth as silk and I had very few issues with PPro or AE for that matter. Sure rendering and encoding took a while but that was CS4!
So after upgrading amid the hype of CS5 and MPE, I moved perhaps too quickly to the GTX480 and applied the 'Hack' with the possibly incorrect assumption that we would see full Adobe support for these cards soon. I expected some instability/issues but am always up for new tech. I have worked in IT and media for 20 years, built all my machines for years and am technically proficient. But this issue has me stumped.

The problem: Instead of better performance, everything has gone the opposite direction. I am experiencing intermittent playback and artefacts on some moving footage, the occasional hang/crash and one or two BSOD's, but quite rarely. Encoding flies however, what would normally take 1 hour to encode now takes 10 mins when direct from PPro and not the Media Encoder, which is amazing but not so useful in the edit when playback has degradated. Things playout but to my editing eye, I can see what looks like stuttering. In fact watching the playback head, it appears to be flashing when passing over some sequences and the result looks like drop frames. I'm in Sydney, OZ, so in PAL land and am acquiring and editing in 1440x1080/25p (SONY HVR-Z7P). It's all progressive, not interlaced for 99% of my footage. On top of this a test burn of MPEG2 DVD (widescreen PAL) produced jumps at every edit point when viewing on a plasma screen. WTF? Not only that, but it looked awful - colour was desaturated and there was a distinct drop in the red channel.
In addition, I am also seeing what looks like pixelation on some pans and tilts and god forbid what appears to be interlacing on complex lighting such as neon signs for example. People passing the camera up close in shot also seem to pixelate badly. None of this has ever ocurred before. Also, applying a simple so-called 'accelerated effect' such as Dip to Black or Cross dissolve brings the red render bar immediately. The type of improvements shown in this Adobe video http://tv.adobe.com/watch/learn-premiere-pro-cs5/gpuaccelerated-effect-performance-enhance ments/ appear to simply not apply in many cases. Other accelerated effects work fine and some non-accelerated effects seem to have improved! Another whacky thing is that if I do import an interlaced clip from say, a handycam from one of my Operator's 2nd unit cutaways and interpret footage and scale to frame size to bring it in, then apply 'Always deinterlace', apprently nothing happens. The footage looks exactly the same whereas in CS4 an immediate change was apparent to the interlacing.
Changes: The only change to the traditional setup I had with CS4 apart from hardware upgrades was movng the CS5 DB and cache to the RAID array as it was previously on the boot drive (tut tut I know, but it never affected performance. Go figure?). New projects re-indexed after this move and the timeline went green and all looked good. Until I started playback. That is when I really noticed things going wrong and still suspect the media cache and DB have something to do with this. Indexing is OFF on the array as well, as I know that it can cause performance hits as WIN hammers the drives constantly for info.
Now, I rarely have more than 3 layers of video including supers, so I am not pushing it. To make things even stranger, sometimes playback seems ok for a while but soon returns to this jerky, stuttering motion. As PPro has no fps monitor (ADOBE - new feature request please for 5.1.1) it's hard to tell what is coming out and I don't really want to install FRAPS to check.
Ghost in the Machine: What's going on Harm? Any idea's? What I am missing? Things seem unpredictable. It's killing me and my business. I realise the card is unsupported but I'm reading alot about people applying the hack and getting great results. Including yourself I believe with the 480.
Thoughts:
- Nvidia driver support in 358 series problem
- Bad card
- Tweaks/config in NTune wrong
- Adobe GTX480 support
- Background services vs. Programs - what's better?
- Some crazy setting in PPro I have wrong but can't find
- PhysX playing havoc with something
- HDMI out vs. DVI
- The flickering playhead is a giveaway - but what does it mean other than it is struggling? Why would this build struggle? This machine should be in the basement at CERN!
- The media cache and DB are corrupted or shouldn't be on the RAID (can move to a Raptor if needed).
- The array and boot drive need a defrag
- A big possibility might be rebuilding the current project from scratch. I have done the open new project, import old sequence, etc, to no avail. I can't find any info on how to completely rebuild a project sequence by deleting the cache and db completely and forcing PPro to remake all it's media reference associations on one or ALL projects. A handy feature if it doesn't exist Adobe!
Any help you could give would be greatly appreciated. Anyone else who is experiencing anything like this or can help (Adobe, Jeff, Chuck, Shooternz or other Community Pro's) PLEASE chime in!
Thanks Harm.
Thanks everyone.syntax3ra wrote:
Can I ask if you think putting the MC and DB on a seperate drive would benefit more than being where it is on a RAID that runs @700MB/sec? Putting it on a drive 1/6th the speed can only benefit it if, as you say "magic happens" by spreading this data around. Is that right? Being in a different location is better than being 6 times faster?
Thanks!
I think what we're really trying to help you do here, is to eliminate variables. While your RAID is undoubtedly fast in sheer data thoughput, there could be some issue with latency or corruption through these often-accessed cache files that's causing you problems. Or not. Putting them on a non-RAID, relatively fast drive will help you eliminate that variable. And I don't think the cache files need a blazing fast HDD. Or the preview files. BUT, if all of this media is not sitting on the same (albeit, blazingly fast drive array), you might experience better playback. Or not. But, at least you'll know.
I will also chime in and say with the GPU-acceleration in the present build of CS5, I don't believe that it offers any no benefit to OC your GPU. Using GPU-Z, I've never seen a GPU load of more than 35% on the single GPU that CS5 uses. My GTX 470 won't even break a sweat. OC'ing this wouldn't change the throughput of only 35% of the load that is being utilized.
I know that there's the temptation to "crank it up to 11", but I think you should try to un-OC your CPU and GPU... and then check and see if this helps your playback issues. Or not. Maybe it's worth a shot... -
With all the interest of the "unsupported" GPUs, I thought it was time to start a specific thread.
Please post your questions and experiences.
Hacking is not advised and the unsupported cards are not ready for production use.

How to make Premiere CS5 work with GTX 295
by marvguitar on 01 May 2010 22:38
I figured out how to activate CUDA acceleration without a GTX 285 or Quadro... I'm pretty sure it should work with other 200 GPUs. Note that i'm using 2 monitors and there's a extra tweak to play with CUDA seamlessly with 2 monitors. Here are the steps: Step 1. Go to the Premiere CS5 installation folder.
Step 2. Find the file "GPUSniffer.exe" and run it in a command prompt (cmd.exe). You should see something like that:
Device: 00000000001D4208 has video RAM(MB): 896

That's fine. Let's add it. Step 3. Find the file: "cuda_supported_cards.txt" and edit it and add your card (take the name from the line: CUDA device details: Name: GeForce GTX 295 Compute capability: 1.3 So in my case the name to add is: GeForce GTX 295 Step 4. Save that file and we're almost ready. Step 5. Go to your Nvidia Drivercontrol panel (im using the latest 197.45) under "Manage 3D Settings", Click "Add" and browse to your Premiere CS5 install directory and select the executable file: "Adobe Premiere Pro.exe" Step 6. In the field "multi-display/mixed-GPU acceleration" switch from "multiple display performance mode" to "compatibilty performance mode" Step 7. That's it. Boot Premiere and go to your project setting / general and activate CUDA Hope this helps -
I have been trying to figure this one out for a couple of days. I found the CUDA mac drivers on NVIDIA's website and installed them. I have been working in Blender. After the driver install I can now switch between CPU and GPU processing, Great. It works, but I am not experiencing decreased render times like I had read about or expected. It's about the same. While using the GPU for rendering, my OS is choppy, leading me to wonder if there is a way to use the NVIDIA just for computing power?
Any help would be grand.
ThanksNo.

Here's some interesting information.
"I asked Adobe to confirm my findings and the following statement: "When using an approved NVIDIA card, CS5.5 performs better using cards with more CUDA cores." A few days later I received a short but to-the-point email confirming that my statement is accurate."
Seems CS5.5 takes better advantage of the CUDA cores in a card, and additional cores now means some significant improvements.
http://www.eventdv.net/Articles/News/Feature/Review-Adobe-CS5.5-Production-Premium-74852.h tmBill,
Thanks for the CS5 5.0.3 results with various GPUs. That 9500 GT is really hobbled by its slow, low-bandwidth DDR3 graphics memory: The MPEG-2 DVD encoding performance with the 9500 GT is nearly three times slower than with even an ATi/AMD GPU. What's more, the H.264 Blu-ray encoding performance is more than two times slower with the 9500 GT than with an ATi GPU.
By extension, the really sluggish performance also applies to the GT 220 and to a lesser extent the GT 430 and the DDR3 versions of the GT 240 and GT 440.
And I was surprised with the results from the GTX 550 Ti: Despite fewer CUDA cores and 192-bit memory bit width (specifically, the GTX 550 Ti has one 512MB chip and two 256MB memory chips, for a total of 1GB on a 192-bit bus), it actually outpaced the older GTX 260 Core 216 despite the latter's 448-bit memory bit width because the GTX 550 Ti uses DDR5 memory versus the lower-bandwidth DDR3 memory on the GTX 260.
So while the GTX 550 Ti is a better BFTB than the GTX 260 and most of the higher-end GeForces, your testing also shows that equipping such a high-end editing system with a really cheap GeForce such as a GT 220 would have thrown that entire system off balance. (Or put it this way, equipping an expensive editing rig with such a cheapo graphics card is like putting more and more mucus inside someone's chest.) -
Unsupported GPU for CS5, part 2
In part 1 all the necessary steps were outlined. Many were successful. I was not. Maybe someone has some suggestions.
What happened:
1. Installed a GTX-480 with the latest drivers 197.75
2. Ran the 'Hack' instructions
3. Steps 1 thru 4 no problem.
4. Then step 5:
Step 5. Go to your Nvidia Drivercontrol panel (im using the latest 197.45) under "Manage 3D Settings", Click "Add" and browse to your Premiere CS5 install directory and select the executable file: "Adobe Premiere Pro.exe"
I selected "Adobe Premiere Pro.exe" in the CS5 directory, but:
"Adobe Premiere Pro CS4" is already available and "Add" does not work. You can't remove the CS4 version.
Does that imply that I first have to remove CS4 (deactivate, uninstall, reboot, reinstall CS4 programs from the MC that I want to keep and activate again) before adding CS5 in the driver control panel? Or is there another proven method or other suggestions?See if you have another file named nvwsapps.xml, either in the folder you listed or in
c:\windows\system32. That file contains the settings for the workstation applications and that's what the Quadro driver uses, but it's sometimes included in the GeForce driver install package. Here's the one for GeForce197.45 WHQL, but unfortunately, it doesn't have any Adobe entries except Photoshop CS4. If you rename nvapps.xml to nvapps.old and nvwsapps.xml to nvapps.xml, the nVidia Control Panel will then be able to display and modify those settings. But unfortunately, until somebody with a Quadro responds, you are somewhat stuck.

After reading all the posts, I have decided on an experiment.
My intention is to upgrade to a new system by November.. I7 930, new board, memory etc.
I currently am running an Intel Q6600, 2.4 GHz, with 8 gig of ram, and a GEForce 8800GTS.
My thought was to buy the video card first, GTX480, and try it on my old system (above) to see how much difference it would make in performance of CS5, including trying the crack.
My concern is the PCIE connector on my board vs the PCIE 2 the 280 calls for. All my reading tells me the PCIE 2 is backwards compatible to PCIE.
Let me know if I am making a huge mistake.Branched and moved.

Hi, I have a GPU question here.
I’m working with both AVI and AVCHD files (Adobe PPro CS4) and I’m planning to migrate to CS5 soon. Can you please advice me what should be the minimum specs of the GPU for taking advantage of the Mercury feature of CS5? What brand?
This is my current card: MSI N250-GTS-2D1G OC 1GB GDDR3 PCI-E

Taking into consideration my workflow (2-3 video layers, color correction across the layers, mostly AVI files), will I notice a significant improvement if I switch for example to GeForce 285 or I should rather stick with my current GPU and invest the money into additional RAM?
Thanks!The 285GTX right now is the way to go unless you want to try this until the Fermi support is out or with a 480GTX

GPU for Premiere Pro CC, Geforce GTX 760?
Hello!
I am looking into purchasing a new GPU for running Premiere Pro CC and After Effects CC. I have gone over the lists of approved GPUs for each software, and I noticed that the Geforce GTX 760 is an approved card for After Effects, but not Premiere Pro. I was wondering if anyone could explain the performance issues I might encounter using the GTX 760 with Premiere Pro? From what I have read, it seems that the Mercury Playback Engine will have to run off of the CPU if an improved GPU is not installed in the computer. Is that indeed the case? And if not, are there other features in Premiere Pro that might not work well with the GTX 760?
Thanks!Adobe's approved list virtually always lags behind hardware releases due to the time it takes to test/certify new cards
My understanding is that PPro CC will use that card without problems -
Ext. warranty for defective Nvidia GPU
Does anyone know if there is an extension on the warranty for the logic board that is replacing the defective Nvidia GPU on my MBP? Its at the shop right now being replaced.
Is it being replaced by a different one or the same board? Hopefully its different. My apple care runs out June 11'. I would think Apple would warranty this since its was a defective product to begin with.Not enough information to go on. This is a good question fro the repair shop doing the work.

Support for NVidia GPU hardware H.264 encoder (NVENC)?
The latest NVidia GPU architecture, Kepler, now has a dedicated hardware H264 acceleration block, NVENC.
It is similar in function/purpose to "Intel's Quicksync" (except that Quicksync works with more codecs: MPEG-2, VC-1, and H264. NVENC only supports H264 encoding.) The company claims the hardware-block can encode 1080p video much faster than the host-CPU alone (probably at the loss of some image quality.) This feature is supported on desktop NVidia GPUs with the model GT640, GTX6xx. And in laptop NVidia GPUs GT640M, GT650M, GT680M (and a few others.)
Does Premiere Pro CS6 take advantage of NVENC? If not, are there any third-party plugins that add NVENC-support to CS6?
If not, I'd like to try writing a plugin that uses NVENC, though that'd definitely be an ambituous undertaking!I have finished a 'proof-of-concept' NVENC Exporter plugin for CS6. This took much longer than I thought it would (mostly due to my inexperience in interacting with Adobe's 'suite' API.) And the beta-plugin is very rough around the edges (no audio or muxing support), and needs some further speed-optimizations, but works well enough for me to start basic testing and behavior characterization.
The following comments are based on my proof-of-concept NVENC-exporter plugin, run on a Geforce GTX650 1GB. The plugin is compiled from the NVidia NVENC Public Beta SDK 2.0 (Dec 2012) and Geforce 314.07 drivers (Feb 2013). The programmer-API to access NVENC is protected by a license-key. The SDK comes with a free trial-key, but doesn't indicate how it compares to a (purchased) retail-key (i.e. does it perform the same but with restricted features/functionality, or does a retail-key offer higher quality encodes?)
First off, how is the video image-quality (compared to the MainConcept H264 that Adobe bundles with CS6)? Based on naked-eye comparisons, NVENC is anywhere from slightly to somewhat worse. As such, since the quality delta was easily discernable at all bitrates, I didn't find it necessary to take objective psnr measurements.
(1) At "low bitrates" (eg. 6mbps or less at 1920x1080 24fps), NVENC is noticeably worse than Mainconcept. The fixed GOP-pattern (group-of-picture) really kills the output-video at scene-transitions, because the encoder doesn't make intelligent decisions about where to place reference-frames.
(2) At "high bitrates" (eg. ~25mbps for 1920x1080 24fps), NVENC is slightly worse than Mainconcept, though now the two are almost neck-to-neck. NVENC seems to have problems tracking very subtle color transitions. For example, on animated/computer-generated scenery (like a Disney cartoon), NVENC had shows a tendency to introduce blocking artificats into sky gradients and other tonal-gradients. Mainconcept was much better in this regard.
Next, what about speed? Speedwise, NVENC easily wins (as expected.)
(3a) For 1080p video, NVENC consistently finished straight "media-export" jobs in Adobe Media Encoder (i.e. straight "in to out" without any adjustments/changes to the source video) roughly 3x faster than the Mainconcept H264-Bluray codec. For example, NVENC needed 30 seconds to re-encoded a 120second Bluray clip. Mainconcept usually took 90 seconds. (Both encodes were single-pass VBR; run as video-only, no audio, no muxing.)
(3b) for 3840x2160 video, NVENC's speed-advantage shrinks to roughly 2x. (This is likely due to a very slow hostmem-hostmem frame-copy operation inside my plugin.)
(4) NVENC CPU-usage hovers between 30-40% during the Adobe Media Encoder session. Mainconcept always used near 90-100% CPU. (My machine is an Intel i5-3570K 4-core CPU.) If someone were comparing NVENC/Mainconcept on a 2-core laptop, the speed-difference would be closer to 6x. Even so, NVENC falls behind Intel's "QuickSync" technology (unfortunately, Intel doesn't offer a Quicksync exporter-plugin for CS6.)
In summary, in its current state NVENC isn't good enough to replace MainConcept in the content mastering and final encode process. But many users may find it useful as a 'quick preview tool'; to generate fast encodes for a bunch of different edit/cut tests (with the intention of throwing most of them away.) -
What laptop to get for CS5 or CS6...
Increasingly there appear questions about which laptop to get for CS5/6.
First, the question is why a laptop and why not a desktop?
Laptops are always at least 2 to 3 times slower than a desktop, they are significantly more expensive than a desktop with the same or better performance and they need a wall outlet to use. Batteries don't last long enough for editing and you need a wall outlet for external components (disks, monitor, BD-R etc.) that are required. All that makes a laptop more like an expensive, underpowered luggable machine.
For video editing machines it is always best to use a machine for video editing only and use a second system for other applications and this is especially true for much weaker laptops than desktops.
So, let me repeat the question: What are the considerations to use a laptop over a desktop? You have to be very clear about it to sell the idea to the one responsible for the budget. You also have to be clear about the performance penalty, if you decide to go forward with a laptop.
OK, we got this out of the way. You have good arguments to get a laptop and you have succesfully sold the idea to the one responsible for the available budget.
So what are your choices and what do you need to look for in terms of specs?
First, let me remind you of the article Adobe Forums: What PC to build? An update... because it contains a number of relevant issues that influence your choice. Basically there are three approaches possible:
Get a laptop from a brand company like Asus, Dell, HP, Lenovo, Toshiba and the like.
Get a customizable laptop from specialist companies like Sager or Clevo.
Get a custom builder like ADK Video Editing build you a system tuned to your needs.
All these solutions have a number of common components, under the assumption you want to edit HD material:
CPU: at least a quad core i7 processor, preferably with hyper-threading. The faster the better.
GPU: at least a nVidia GTX 660M or better with 1+ GB DDR5 memory.
Disks: at least 2 internal 7200 RPM disks.
Connections: minimum is eSATA plus USB3 ports.
Monitor: at least 1920 x 1080 resolution and 15.4" screen size or bigger.
Memory: bare minimum is 8 GB but workable is only 16 or 32 GB.
Looking at brand names one may come up with a short-list like:
Now, in their standard configurations they are all lacking on some aspects. Insufficient memory, only single disk, or lacking connections. If these can not be configured to meet the above practical minimum requirements, where at least 2 disks is the most crucial, there is only companies like Sager and Clevo to look at. Something like this is about bare minimum, because of the underspecced video card:
Despite the price this will still be around 3 times slower than an equally priced desktop. If that performance penalty is too big, then one can consider a system like this:
Again, despite the price, this system will still be more than 2 times slower than a far less expensive desktop, but hey, you knew that when you decided on a laptop and got approval for the budget, right?
The last option is to go to a custom builder to get a laptop that is exactly tuned to your needs and budget. It will not be less expensive than the Sager route, but it will get you the best balance between performance and price for your needs. Additionally, you get great service if ever needed.
To sum this up, a laptop is a compromise. A compromise in performance and price. It is not for the faint of heart, faint of wallet. It is not a laptop, it is a luggable system on a wall outlet. An alternative is coasters under a desktop system and you can use other wall outlets as well, but with a better price and far better performance.
I hope this will help people to decide if they really need a laptop and if affirmative, to get the right system for their needs.As usual, Harm has provided very knowledgeable and helpful advice in this matter. I would like to add that if you are inclined, and feel it's worth a gamble.....New Egg has been selling refurbished Asus i7 laptops that have almost all the necessary components for a lower price than normal. You may have to add more memory yourself and add a quality SSD for OS and programs and pagefile, ( cloned from the supplied drive). Then, use the supplied drive for media and all else in the second bay....or, as an emergency backup of your original configuration. I am not sure,but I think if you put a second Marvell controlled SSD in the second bay instead,( Corsair Pro or Plextor Pro...no Sandforce), you may get the benefit of SATA III speeds from BOTH drives for best laptop performance.....I am not sure if earlier criticisms of SSD degradation still apply with these newer Marvell controlled SSDs.
I DO know that my old Asus G73JW tested MUCH FASTER on Harm's PPBM5 benchmark when I added extra memory,( from 8 to 14GB ), AND used a Corsair Force 120GB SATA II SSD in each of the two internal drive bays. On that site you can see similar laptops to mine performing way slower using less memory and conventional spinning HDDs. At the time, I was careful to choose SSDs that had a high read AND write speed. I have had no issues with my SSDs. I also have used the Seagate Momentus XT hybrid HDD as project drive.....and scored lower on the PPBM test,( not submitted).
Harm is right.....any laptop will not approach the performance of a good desktop setup....not to mention PPro CS 6 appears to be even more powerful and demanding than the 5.03 I'm using. People are reporting needing at least 32GB memory and more than 2GB video card memory to get better performance.
Someone posted about Exotic PC selling upgraded laptops, ( some Asus) with up to 32GB memory and muliple HDD configurations....you may be able to upgrade a laptop similarly yourself for less money. Watch the sales at Tiger Direct and New Egg....you may find some thing workable.
