    290x (Still Negative Crossfire Scaling)

    misko1546

      Hey ppl,

       

      I am still having issues with crossfire for my 290x CF. I have tried the fixes suggested by amd as well as people on the web but no luck.

      I am able to run the game all ultra and distant foliage at high and i get 55-90 fps with a single 290x (this includes tessellation fix for amd and hairworks)

       

      Turning the second gpu on and I get 40-50 fps no matter what settings I use, it cant go above 50fps. My little brothers computer who is running a 6990 also lags.

      Before the drivers were released I thought yep need drivers for CF. I tried new drivers on that setup as well and same performance, very bad even on all low, game is at 30-40 FPS on all low on that

      system and a 6990 is not a bad card and should be able to handle the game on high.

       

      I have a 5820k CPU, maybe can be a driver glitch with a particular cpu.

       

      Any help is much appreciated, thanks.

       

      Regards,

      George

          OK guys silly me and apologize for found the issue, was on boarder full screen and not full screen :/

          Changed to full screen and fixed right away, has minor flickering, nothing annoying.

           

          I still have questions to raise for the 6990. What performance is expected of it? The game on my lil bros PC cannot get above 60fps

          on all low which I think is clearly not right. I haven't patched the game on that PC yet so maybe this the issue? I was assuming the 6990

          will be able to push medium - high. PC  has older Gen i7.,
