Thanks, that was exactly what I was looking for!

For anyone else who was a bit confused on where to go, try this:

Start > Right click "My Computer" > Properties > Advanced System Settings > Advanced Tab > Performance Options

Then you should see the screen.

Thanks again!

Well video out on the 7970 did make it usable, though I still wish there was a way to turn off hardware acceleration. Using the desktop causes the hashrate to drop by over a 100. Can't fit another GPU on this rig because of my case unless I dismantle everything. I guess I'll do what I've been doing for the past 2 months, use my laptop. Though now I guess if I need to code I can use my desktop for that.

Thanks for the suggestion, I had that line at 100 previously, changed it to 80 then 50 and my PC is still unusable. My hashrate never even dropped. I'm using 290s.

If I remote from my laptop it's usuable, I'm assuming because there is no GPU acceleration, but right now it is not unless I lower the intensity.

EDIT: I'm running 3 290s and 1 7970 on this rig. I know with just the 7970 hashing my PC is usable (because intensity is 13). If I video out from the 7970 instead of my 290 will it help? I haven't had time to test today, but I know disabling my current GPU and keeping the other 290s mining didn't help do it doesn't seem likely.

Is it possible to turn off Hardware acceleration in CCC? I'd like to be able to use my computer while mining at a high intensity. The option in Windows is grayed out for me.

Well I really wanted to reply to a thread but I guess I have to reply to this one first. Only 3 hours and 43 more minutes to go!
