Speedgrade CC 2014 becoming increasingly slow while working on a project that was direct linked from Premiere CC.

Question

Speedgrade CC 2014 direct link from Premiere Pro CC 2014.  The application is becoming increasingly slow when making any adjustment or just selecting any buttons on screen.  While working for and hour on my project it is now bordering unresponsive.  In addition it is causing the Finder to become slow and any other applications such as Safari and Mail. 
I'm on a Mac Pro5,1 OS 10.8.5, 6-core intel xeon 2.93GHz, 16gb Ram, Ati Radeon HD 5770 and NVIDEA Quadro 4000 cards. 
I'm hoping this is just a setting in speed grade and not a bug.

First, Davinci and  the Adobe DVA's (digital video apps) utilize resources very differently from each other. That said, your hardware is making me green ...
This is something that should fly on your system, so ... I would definitely suggest my previous thing of running that benchmark testing ... it will tell you how your system runs the Adobe stuff, and indicate if anything could be modified so it would work better. Some people with FAR less a system than you're running fly through a DL session. Even my system with only four "real" cores (8 "logical" ones ... whatever ... ), 16Gb RAM, and a GTX770/4Gb vRAM and multiple internal & eSATA drives to split things up for throughput sustained stuff, has been running pretty smoothly. Even though it wasn't using much of the video card, which screams for many people in the Adobe DVA's. This latest set of improvements has pretty much nearly eliminated Sg using it ... so we'll have to puzzle out WHAT is causing Sg and the other apps to ignore my card when in identical setups it's a real beast.
That's the kind of thing that can drive the engineers up the wall. Some of the systems that have had terrible problems such that users have been on here complaining that "no on could possibly be running "serious professional footage & effects" on a system like theirs, didn't you idiots test it?" ... have received the response ... that Kevin or Al or someone is running a completely identical system to almost all tiny respects ... and is flying with 6k footage running a ton of PrPro & Ae effects then worked heavy in Sg. And coasting at it. Not that they at all challenge that the user's system is nearly unusable at the moment ... but figuring out why on two nearly identical setups it works so differently can be rather tedious with hundreds of thousands of lines of code involved, various plugins, and maybe a 2/3rds moon on the third Tuesday.
Like mine. I know quite a few people use this card on the Adobe apps and it's really flying for them. It's been re-installed twice on mine, Windows and all monitoring systems see it fine, but ... even after multiple installs and CC cleaner attempts and such it's not "seen" properly by any Adobe app. So ... off  to run the benchmark to see what all in my system is doing fine ... and if there's any hint as to why that card isn't getting used.
Also ... it would maybe be useful to get Dennis Weinmann or Fran Roig to jump in, maybe get a sample of your project file or info on those LUT's or something, to see if they've got any ideas. Trouble is most of Adobe's staff is on Winter Break for the next week plus.
