im folding on my gtx260 using vista64bit, and its not going very quick, it seems to do a bit of work then stop, then do a bit more then stop again if that makes sense, and this is confirmed when i put the viewer up, now i was watchign a video of someone folding on youtube and they have it going constantly, what going wrong in my case?
My GTX 280 does the same and I've read that it's perfectly normal for these units.
