Benchmarks: Metro 2033, S.T.A.L.K.E.R.: Call of PripyatFor testing Metro 2033, we used Fraps to gauge GPU performance based on 60 seconds from the "Chase" level. The game was tested with DirectX 11, but we disabled Tessellation as it hammered performance too severely. Anti-aliasing was also disabled and instead we used the default analytical anti-aliasing with 16xAF.
The GeForce GTX 590 surprised us in Metro 2033 as we found it to be 20% slower than the Radeon HD 6990 at 2560x1600. Nonetheless, it maintained a 62% lead on the GeForce GTX 580, 77% on the HD 6970 and it creamed the HD 5970 by a 96% margin.
S.T.A.L.K.E.R.: Call of Pripyat
S.T.A.L.K.E.R.: Call of Pripyat has an official DirectX 11 benchmark tool, but we decided to dump that in favor of Fraps. We recorded 60 seconds of the first level, dubbed "Zaton".
Repeating the results we found in Metro 2033, the HD 6990 showed superior performance in S.T.A.L.K.E.R.: Call of Pripyat. The GTX 590 was 15% slower than the competition, while it was just 22% faster than the GTX 580 at 2560x1600.
