CrossFireX is not broken here though... it seems to be working fine for all my games bar Saints Row 2 and Blur so I suspect it has been disabled for those as both games have serious issues when using both cards. I tested Star Wars: The Force Unleashed, Mass Effect 2, Batman: Arkham Asylum, GTA: Episodes from Liberty City, Just Cause 2, Oblivion, Red Faction Guerrilla and Battlefield: Bad Company 2 and all of them work fine with CrossFireX (although the latter has weird framerate drops in the menus for some reason). *EDIT* There's definitely something a bit not-quite-right about these drivers. Just loaded up Call of Duty: Modern Warfare 2, which has v-sync on, and I noticed that just before the game starts there's the same weird framerate drop to 1 fps in the loading screen just before the game starts that BFBC2 had. Then when the game starts it shows 40 fps before jumping to 60 fps and staying there. I tested without v-sync and the framerate on the same level (oil rig) was 330 fps (and 1,000 fps in the menus!!!) so there's no way it should ever have been as low as 40 fps. Maybe it has always been like that and I've just never noticed it before (i.e. I'm getting paranoid because of all the negativity towards these drivers)? Is this what people mean by CrossFireX not working, i.e. it *is* working but just not as smoothly as before?
