Greetings,

well I am really not an OS / HW expert, but this is my simple observation. I currently have:

and before GTX295 I had 2x8800GTS512m (but this has no importance regarding this issue)

Until nvidia driver line 179.xx there were no problems for me, even SLI split screen mode worked like charm. Then the disaster came, but suddenly with 182.50 the problem is gone for me (well, SLI is unfortunately no show with il2 any more). What ever anybody says about who/what is the generator of this, my opinion is coming-up directly from my previous sentence.
