Benchmark Results: H.A.W.X. And DiRT 2
H.A.W.X. demonstrates what we consider to be the only real puzzling result in our test suite, with the new Radeon HD 5570 performing right on par with (or a little below) the Radeon HD 4670. Regardless, performance is acceptable across the board.
In DiRT 2, the DirectX 11 effects are hard to notice and definitely not worth the performance hit that the sub-$100 Radeon cards suffer.
