Benchmark Results: S.T.A.L.K.E.R. Clear Sky
Water effects, vegetation and lighting set Clear Sky apart from many other first person shooters, but those added details can tax nearly any graphics system. We began our tests at the standalone-benchmark’s High preset, hoping to see smooth game play across all cards and resolutions.
Unfortunately, neither GeForce GTX 285 could smoothly play the game at 2560x1600, nor did increased graphics memory help. Both single-GPU cards also suffered at 1920x1200 under the “SunShafts” test, stalling at a few points along the test map.
Moving up to the Ultra quality preset dropped both GTX 285 models equally, while the GTX 295 maintains its lead. Yet, not even the GeForce GTX 295 could pass the “SunShafts” test, its 25.3 FPS result dragging the average down to 41.6 FPS.
Add 4x AA to the “Ultra” quality preset and you’re lucky if even the dual-GPU GTX 295 can play every scenario at a meager 1280x1024 resolution, though the average of all tests doesn’t reveal that problem. Notice that the GTX 285 finally edges ahead at 2560x1600, though stutters and stalls prevent the game from being playable at this setting.
