GPU questions
How much is performance affected by running the display in the gpu client. Also after about a minute it starts moving very choppy at like one or two frames per second. if i put my mouse over the window it goes back to normal speed (ridiculously fast) what causes this. i have a e7200@3.4 and a 9600gt@750 1950 2100. also i am running the cpu client at the same time if that makes a difference.

The viewer is still full of bugs, and it's better to not use it.

Re: GPU questions
Welcome to the forums!
Performance is severely affected by using the display - it uses a lot of CPU time and some GPU time to display, all of which slows down the calculations. It slows down after one minute intentionally, because that allows the caluclations to speed up again as much less load is being dropped onto your hardware from non-essential (for F@H) calculations. It goes back up to normal speed when you mouse over the window because it then assumes you wish to watch, regardless of the fact that it is slowing down the calculations.

The default speed is 1 FPS which is rather slow, but considering the fact that v5.03 only displayed 100 frames per WU (I think that's what it was) even 1 FPS is a big step.
The real problem is that the folks at Sony created a dynamite viewer for the PS3 client and the PC folks said "I want one like that" Well, the PS3 folds at a pretty good rate on it's Cell processor (at least compared to a CPU) and there's an essentially free GPU which, with the right programming, can do the graphics. No such assumptions can be made about the PC so steps were made to let it go fast for a short time and slow the rest of the time.

Re: GPU questions
thanks for the info i guess ill have to stop sitting in front of the spinning proteins pretending i am a creating a virus to destroy the world. i wouldn't want to impede the folding maybe i'll learn to knit or something. does anybody have any ideas how many points i should be getting per day i think i need to tweak some settings or something i'm only getting about 2-3000 partly because the cpu and gpu keep going back to the same core after awhile. oh yeah i'm no computer scientist but why don't they just make the resolution and frames per second like one third wouldn't that make it use about a ninth as much resources and still look good and move at reasonable speed and be useable.
