I'm still kinda wondering where you heard that because I haven't found any article linking g92 and 8900 together. That doesn't even make sense if you think about it. G80 and Geforce 8... How could G92 no be referring to Geforce 9?
And how do you know about the performance of Crysis on unreleased cards anyway?
He "supposedly" has a friend that told him some features from Crysis would be disabled since the game wouldn't be able to run on any current gpu's or even the g92's. His post is as just as false as this whole thread.
