In some hl2.exe source based games (Counter-strike source and team fortress 2) crossfire doesnt work. I contacted valve and they informed me they are crossfire enabled games and i should contact AMD support so here i am. I get crossfire support in the new counter-strike GO which is source based. i have portal 1/2 but ive not got them installed so i cant tell you if i have crossfire in those.
It wouldnt be a problem but with only 1 graphics card working at 100% gpu load it gets hot, 100+ degrees which means more fan speed which means more noise. Now 2 gpus running at 60% load would be quieter so why isnt it working? any ideas?
gfx - MSI R6970-2OM2D2GD5 x2
mobo - Asus crosshair V formula
CPU - AMD Phenom II x6 1100T
Memory - 8GB gskill rapjaws x
PSU - 1000w ocz
Crossfire works in all my other games modern warfare 3, battlefield 3, track mania 2 etc just not tf2.
