I bought a 5870 last spring and by itself it ran sooooo smooth. With crossfire however I have had nothing but problems. 10.5 has been the only driver that worked for me, I tried everything through 10.10d didnt have much luck. I tried 10.11 today and went to go play some bad company 2. one of the big release notes of this patch was that crossfire no longer became disabled after task switching on this game, well id be fucking nice if they had it enabled in the first place. gpu 1 100% gpu 2 0%. sweet ati you guys are morons. anyone have this working?
