7950 crossfire performance in crysis 2

post #1 of 3
Thread Starter 
Hi, I am having issues with a major performance drop in crysis 2 after I updated to v1.9 with dx11 and hd texture pack. It went from silky smooth to sort of slow motion ish. My system specs are 2x gigabyte 7950's @ 900 mhz (factory overclock), i5 2500k @ 4500mhz, asrock fatality mobo, 2x 120gb ssd's in raid 0, 16 gb 1600 corsair dominator, corsair hx 1050 watt psu. I have also downloaded the latest profiles and drivers that were released a couple days ago.

I am gaming at 1080p with all settings to ultra, hd textures and dx 11 enabled. When I run it in windowed mode the gameplay goes back to silky smooth or when I disable dx11. According to this review: http://www.tomshardware.com/reviews/radeon-hd-7950-overclock-crossfire-benchmark,3123-17.html this card is supposed to perform better in dx11 then dx9. I have also heard that windowed mode is supposed to slow the game down in crysis 2. What gives?

Btw the cards perform well in Heaven and furmark so they are fine.

Well after a windows update that included a integrated graphics update I am averaging 80 fps. It seems that either the windows update did it or the computer needed restarted even though I'm pretty sure I restarted when I installed the newest AMD drivers.
