Any Fix for DX11 Crossfire Performance

Post » Wed Oct 19, 2011 9:26 pm

Hello People,

I just got Crysis 2 for my PC, already played on Xbox so I wanted to give it try PC DX11 specs

My config

Phenom II 955 3.2 GHz
8 gb DDR3 Kingston HyperX Blu
XFX Radeon HD 6850s Crossfired 1GB each
1000W Power Supply
Resolution 1680x1050
Catalyst 11.10 v2 with 11.9 Cap2
Stock settings
I have played it both DX11 and DX9 Modes.

In DX9. the Crossfire works so good (each GPU at 80% to 95 %) that game is running continously at 60 frames, no problems.

But when I switch to DX11, wow 2nd GPU drops to ZERO, and only first one is working. Heavy Tessalated places tend to drop frame rate to 20, MY average is around 30. Particle effects tend to slow it

I was hoping anyone knows a fix or boosting performance in Crossfire. I have seen some posts but didn't find solution or overlooked

Battlefield 3 beta was having same problem until they released CAP2 which boosted performance ALOT. I presumed DX11 cap would avaialable already.
