Left 4 Dead

The game runs on the Source engine and has an integrated benchmark, but the latter does not report the bottom speed information.

The GeForce GTX 295 is lagging behind the Radeon HD 4870 X2 throughout the test and only catches up with the latter at 2560x1600. When overclocked, Nvidia’s solution takes first place, being short of notching 100fps and leaving the GeForce GTX 285 SLI tandem behind.

S.T.A.L.K.E.R.: Clear Sky

To achieve a playable speed in this game we disabled FSAA and such resource-consuming options as Sun rays, Wet surfaces and Volumetric Smoke. We use the Enhanced full dynamic lighting (DX10) mode for our test and additionally enable the DirectX 10.1 mode for the ATI cards.

The GeForce GTX 295 delivers a comfortable performance at 2560x1600 but AMD’s solutions can do the same and even surpass the GTX 295 in terms of bottom speed. Oddly enough, everything is completely different at low resolutions where the Radeon HD 4870 X2 and Radeon HD 4890 CrossFireX are inferior to Nvidia’s solutions. Anyway, the new GeForce GTX 295 is better than its opponents in usability, power efficiency and noisiness.
