Hi, im getting some gpu resets (sometimes even reboot computer) playing some
games (League of legends & starcraft2) using wine (patched for d3d)

I have to say it only happens using certain settings, for example using
"character quality" option from league of legends setting to very low/low game
loads normally. if i set to medium or higher then causes GPU reset loops untill
game crash/computer completly freeze(need reboot)/or if i'm enough faster, kill
process from tty.

If you need, i can try to make a movie showing problem
