Suffers from severe flickering on GF8800GT and apparently did on cards used only 2-3 years after its release (I think it worked fine with GF2MX and R9500Pro), haven't found a fix for it and the issue is not visible in any screenshots I've taken (somehow the scene syncs perfectly for each screenshot). Twiddling with NV's control panel had no effect either nor the minimal options in the game itself. Therefore the cause of the issue is unknown. No other games I know suffer of similar problem to give any indication for possible solutions either. The glitch is similar to vsync tearing but instead of tearing, you have this horizontal band spanning the whole screen with no texturing for most objects, giving you a very distracting sort of x-ray vision.
