F.E.A.R. 2: Project Origin

Things change again, and Radeon HD 4770 CrossFireX wins in three resolutions out of four. It yielded to GeForce GTX 285 only 8% in 2560x1600 resolution, but maintained sufficient average and minimal fps rates for comfortable gaming. Not bad at all for a multi-GPU tandem that costs only around $200.

This game is based on Source engine and has built-in benchmarking tools that report no minimal performance readings.

Due to higher GPU clock, Radeon HD 4770 CrossFireX manages to outpace Radeon HD 4850 X2 in all resolutions, and the first three – to successfully compete against GeForce GTX 285. Unfortunately, in 2560x1600 resolution our today’s main hero gives away its leading positions and starts losing to GeForce GTX 275. However, it still manages to maintain acceptable average performance level.

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

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

We didn’t expect Radeon HD 4770 CrossFireX to work any serious wonders here, but the results surprised us in a highly positive way. This configuration proved fats enough for 1680x1050 resolution and even for 2560x1600 with a few allowances. The only solution that could pose any serious competition to the ATI solution in question was GeForce GTX 250 SLI tandem.
