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
Device: 00000000001D4208 has video RAM(MB): 896
Vendor string: NVIDIA Corporation
Renderer string: GeForce GTX 295/PCI/SSE2
Version string: 3.0.0 OpenGL version as determined by Extensionator...
OpenGL Version 2.0
Supports shaders!
Supports BGRA -> BGRA Shader
Supports VUYA Shader -> BGRA
Supports UYVY/YUYV ->BGRA Shader
Supports YUV 4:2:0 -> BGRA Shader
Testing for CUDA support...
Found 2 devices supporting CUDA.
CUDA Device # 0 properties -
CUDA device details:
Name: GeForce GTX 295 Compute capability: 1.3
Total Video Memory: 877MB
CUDA Device # 1 properties -
CUDA device details:
Name: GeForce GTX 295 Compute capability: 1.3
Total Video Memory: 877MB
CUDA Device # 0 not choosen because it did not match the named list of cards
Completed shader test!
Internal return value: 7
------------------------------------------------------------------------------------------ --------------------------------------------- If you look at the last line it says the CUDA device is not chosen because it's not in the named list of card. 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 posted yesterday that GTX 470 seems to work.  Jury is still out on the stability and functionality though.  Take a look at my other posts for details.
UPDATE:  There are rendering errors with the Fermi / GTX 400 series from what I understand.  Sorry guys...Not ready for prime time yet.  Not production ready yet.
Even if so, keep it on for editing and turn it off for final rendering then, no? So it might still be a huge help even as is.
Maybe it is just a bug in the current nvidia fermi driver and will fixed the next driver release?
Yeah it does seem fairly disappointing that the HW still seems to be untouched for codec decoding, using video card decoding assistance makes a ridiculous impact (although it might make it harder to also use CUDA then, but I almost bet, for h.264 video, if most likely not for any other sort, that shifting that to decoded accel and doing the CUDA stuff back on CPU would be faster on average, i also wonder if it might not be possible to use both at once, at the very least with some buffering tricks, anyway i'm getting into wild speculation now). Straight h.264 still drives the CPUs like wild. At least the Mercurcy engine is now just barely fast enough in software to handle it on a reasonable fast machine though, so whatever the actual story it certainly is quite a step up from CS4 for sure and one a reasonably fast machine it will do pretty well unless you go crazy with it.
