Yes I am getting the same issue. :-(
Core 2 Quad with 4 Gig RAM with 2 GeFORCE GTX 260s. I have tried everything suggested above plus running on just one card and even rolling back the drivers, to no avail. My system run all my other programs (ie IL2, SH4, FSX, GRAW, COD4 etc etc) without any hickups.... any other suggestions?
Many Thanx
