I've had the same problem with San Andreas the last few days. I'm running an ATI Radeon 9550, and during the game (about every 20-30 mins) it would freeze, sometimes VPU would recover the game, sometimes not. By playing around with pretty much every setting I could find, I finally seem to have got it working (been playing the last few hours with no probs!) VPU Recover -> on Smartgart AGP Settings: AGP Speed -> off Fast Write -> off Seems to do the trick nicely! This kind of prob seems to be quite common, hope this helps.
