[miguelaje]

Hi, i have manjaro KDE width catalyst propietary drivers, the system recognize both GPUS but the benchmarks fps its how if only 1 gpu its working. I was tryed in other distros with similar results, only one moment in ubuntu i could be 2400 fps but missing at restart. Only 1200 fps in glxgears (with i7 930). How exactly i must configure aticonfig and/or xorg for a dual GPU card how 5970?
