Hello,
I am using ATI CF Xtension in order to enable both cores in my 4870X2. I have triple monitor with TH2GO and noticed a big improvement in FPS.
The problem is that I can't make REX to work anymore. I suppose that it search for fsx.exe filename, but I had to change the .exe to "crysis.exe" for ATI CF Xtension setup.
Thanks in advance!
