I might be having some problems with my R9 290X Crossfire setup, however as I am not experienced with AMD cards (these are my first AMD cards since my HD4870 which burned out), I am not sure whether I should be getting these results. So I would like some assistance.
Here are my test results.
Unigine Heaven Benchmark 4.0
Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz (3499MHz) x4 <-- This has been OCed to 4.4GHz
AMD Radeon R9 200 Series 184.108.40.206 (4095MB) x2
2560x1440 8xAA fullscreen
Custom <-- This is everything maxed out.
I have been having problems with some games having worse performance with Crossfire on, and then some problems with visual bugs in games, and micro stuttering with vSync turned on etc. So I am trying to check whether I am doing something wrong or whether there is something wrong with my setup or whether this is the level of support from AMD Crossfire and the latest cards are getting (no offense meant with this, however I haven't had the best of luck with my HD4870 and haven't heard too many nice words regarding AMD and support).
if you haven't done it yet for some reason download http://www.guru3d.com/files_details/display_driver_unin... start your PC in Windows safe mode and run the driver sweeper. Get rid of everything that appears on the list related to AMD or nVidia. Then restart your PC, download and install the latest AMD drivers.
The sun is far too bright, and I am getting stuttering with bugged water ripples. If I turn of Crossfire, everything is fine, however I cannot play with ANY ENB with more than 20-30 FPS. No matter whether I have mods installed or not. And from videos I've seen, I should be getting far better performance. The stuttering is present in most games with vsync turned on though.
Anyway, any idea if I can do any other benchmark to check? My problem is that a lot of games suffer from lower performance if Crossfire is on, and I do not know whether this is normal.
So any benchmarks I can do?
Or maybe I could get some info from members on here regarding what kind of performance they are getting at 2560x1440 with Crossfire 290Xs so I can compare to the actual performance I am getting? Or any other way to check if both cards are running as they are supposed to? Since the lower performance with Crossfire makes zero sense to me (coming from a previous nVidia SLI system), and I want to check if maybe one of my cards need to be replaced.
