Is there any good program out there that can stress out my video card overnight, but also automatically stop if it finds a processing error. I want something like Prime95, but for my video card. I want to stress test my overclock for 24hours, but don't want to sit here and have to watch 3DMark, or Kombuster, or anything like that to see if it artifacts. And I don't want to leave a program looping overnight and NOT watch it because if it starts artifacting I want to stop it before I kill my card. I know people use GPUs for folding and such, so shouldn't there be a program similar to Prime95 that just uses the video card to process data, then stop if it has an error?? Any ideas?? ATITool seems to be the closest I can find, but it's old and not working right with my system properly so I can't use it. Any advice would be great!! Thanks guys!!
