So apparently Folding@Home's GPU client and minecraft just don't get along. I was playing the free sandbox version... the java web version... and my PPD was pretty low. I looked and saw that it kept getting an UNSTABLE_MACHINE error. So I deleted the data and tried again.. still no luck. Finally closed Minecraft, and now I'm back up to 9k PPD for today, up from about 1500-2k. anyone else notice this issue with minecraft? I guess I'll just have to run minecraft on my laptop while my pc is folding.
