Recently I was able to get a really good deal on a HD6990, a friend bought 1 to upgrade from a 6970 and couldn't fit it in his case so asked if I wanted to swap my 6970 and pay the difference. w00t!

Problem is I can't play Crysis 2 with this card, I either get white flashing bars or since latest 1.4 patch I get black patches flashing on and off all over the screen.

I have used  Crysis2AdvancedGraphicsOptions.exe but while this gives me advance graphics options I can't seem to get it to play the game properly.

When I play in Windowed mode it fixes the graphics glitches but my fps drops from around 88 down to 44.

Does anyone know how I can fix this?

My specs at the moment are:

• AMD Phenom ii X4 965 (3.4ghz Quad core)
• Corsair H50 All in one Water cooling kit 
• Asus M4N89GTD mobo
• XFX Ati Radeon HD6990
• Patriot Viper 4GB (2x2GB)
• OCZ 750watt Fatal1ty Semi-Modular

I'm guessing you've updated all the drivers as well as the game if possible?

To play Crysis on a HD6990, you need more skill.

Can you choose to only use one gpu in the cataylast control center? Hopefully that would get rid of the flickering or graphical anomolies. But you won't make use of all the frames your suppose to get.
