Caporegime
I read one review of gpu performance tests with Crysis 3, they named it the system killer, and this was only on High settings with 4xmsaa medium .
Titan SLI @1920x1080 had very nice framerates (95fps) but @5,760x1080 was just under 40fps.
If I am honest, I was expecting tough but that is seriously tough. Everything was set to the max and that was unplayable. 2*MSAA wasn't much better in honest but playable.
