Benchmarks: Ultra - MSAAx4 Enabled
We ran some tests with MSAAx4 enabled alongside HBAO+ which, again, causes a bigger performance hit on AMD cards than Nvidia. As a result, when running at 1680x1050, the HD 7970 GHz Edition averaged only 47fps -- the same as the GTX 760.
Upping the resolution to 1920x1200 yanked the Titan from its position in the mid-70s, while the HD 7970GHz Edition and GTX 760 were reduced to 40fps.
Playing at extreme resolutions such as 2560x1600 with MSAAx4 enabled requires a multi-GPU setup, as the Titan only managed 42fps.
