DX11 mode = terrible crossfire scaling

Post » Mon Jul 18, 2011 2:33 am

Hi guys, i just recently notice that when i switch to dx11 mode.. there's poor crossfire scaling as pictured below.. but when i turn off dx11 and in DX9 mode + enabled Maldo's HD mod (2nd Picture), crossfire scaling would sky rocket to 93%... I have 2x 2gb 6950 btw. I havent had the chance to get my hands on my pc in 3 weeks due to some busy schedule, so I gathered all necessary info in order to update this game to its latest version, Maldo HD texture pack included. I was surprised when the patch 1.9 along with DX11 and HD texture pack came out...=D So, what gives here? is this old news?.........

Yeah, you need to switch to a different graphcis setting, then switch back again, for crossfire to kick in on my machine.

Just out of interest, what CPU have you got?

Crysis 1 only had 40-50% scaling at best at first. The problem is that catalysist 11.6 isn't really optimised for Crysis 2 dx11 for crossfire. However there is apparently a big boost from the 11.7 beta drivers but they are use at your own risk until the offical drivers are out.

It's wierd, because when I switch the graphics about, I do get near 100% use on both GPUs:
