Hi, I have the NB (Schenker XMG P502 PRO) already almost a year and I like it, but it has a little "quirk" anyway. If I have been playing games (eg SC 2 or D3), there is the phenomenon that after some time FPS dips are recorded and the NVidia drivers (no matter which) crashes and resets itself or the OS in hanging up. My guess is that it either has to do with the Optimus technology or there are problems with the p-states-chanes. Temperature all the time is ok (~ 65 degrees max during 3D games). The problem can only be solved, if I assign a solid P-State (atm P5 with original chip / Ram-Clock) with nvidia inspector. After gaming I change it back to idle mode manually (P8). And that's no fun ;D, so I am looking for solutions; D. Maybe someone has ideas.
