Strange performance issue

[Gamerkought]

Nope. The temperature keeps stable (according to everest). It is just within the game at first it works fine, then fps suddenly fall with no reason. Also, game randomly could be started in some cases normally and in other cases with low fps. Seems like something wrong in the code. I have got last DX and nvidia driver updates.

Seconded. Temps are fine, drivers are upgraded. My other OpenGL games run fine.
