WAIT! I just realized I forgot an important step that was outlined in the ParkOz set-up.
Install Crysis SP Demo.
Backup the Folder of Crysis SP Demon\\Game\\Config.
install the Retail Version of Crysis.
Overwrite the backuped folder to the installed Dir.
run ConSole window and Type r_MultiGPU and Press Enter key.
0 means CrossFire off, 1 means on, 2 is auto
I will upload the SP Demo config folder so noone has to re-download the demo. I just overwrote the file, I didn't have to do a fresh install before replacing the folder.
The console part is just to check or manually activate CF in Crysis.
Sorry all! This will make all the difference!!
