I get around an 11000 on Firestrike which is seemingly low compared to other results. Also, whenever I play Just Cause 3, a game with no crossfire support, I sometimes have massive fps drops, especially in cities, that are embarrassing for my rig.
Wow, so many responses!
Here's a link to the Witcher 3 running at 60fps with 2x R9 290x before crossfire drivers were even released - http://sapphirenation.net/optimizing-the-witcher-3-wild-hint-for-radeon-crossfire/
The thread before suggested that my CPU might be a bottleneck, but I was doubtful.
Basically I'm getting an average of 40 that stutters and drops to 20 fps when I should be getting constant 60. (I practically copy pasted this from a dead Tom's Hardware thread that is now dead and no help) Specs: CPU: i5 4690 GPU: 2x XFX DD R9 290X 8gb Mobo: GA Z97x-SLI Ram: 8gb G. Skill 667mhz Hard drive: 1TB WD PSU: XFX Core Edition PRO850W I know that I should be getting 60fps average. Everything is turned up, except for Nvidia Hariworks. I'm running the 15.12 drivers and my cards are set in Uber mode with a clock speed of 1375. Whenever I run Heaven benchmark I get a score of 2500-600, and get a 60fps on the Shadow of Mordor benchamark at 4K. I also set the EnableTemporalAA=false in the rendering.ini file in the Witcher 3. I get practically the same fps with crossfire disabled. There is also a lot of sudden dips in fps and stutters while playing. GPU Usage during gameplay:
