sys specs: opteron 64 170 (dual core, 2GHz), 2GiB RAM, GF 7600GT, WinXP Home SP2
nvidia forceware 169.21, DirectX March 08
problems with bioshock v1: regular stuttering (gaming for 30 secs, wait one sec, game 30 secs, wait one sec, etc), no sound interruption though
patched-v1.1 problems: menu flickers (black), game runs well for a couple of hours, then it crashes and gives me a nv4_disp dll error. dxdiag shows no problems.
other unreal3-based games run well (->stranglehold, ut3).
any help appreciated.
