I'm currently GPU folding with Cat 7.2's under vista, and im getting alot of units that start and imediatly give up (you may see in my stats at times i have 60 odd units and 60 points in one update) if a unit however gets going it keeps going.
Under vista gpu folding i think is much slower however it uses next to know cpu time (out of my dual units one is set to 95% and i still have 1% cpu time overall remaining)
