I used this benchmark back in April 2009 in my original coverage ofthe GeForce 275 versus the Radeon HD 4890, but some new patches havecome out that have greatly impacted performance. I also didn't show thedifferences between DX9, DX10 and DX10.1 the first time around, butthis time I will.
For this game VSync was turned off, but Antialiasing was turned on and set to 8x for better image quality.
All of the DirectX 10 options were set tohigh including Ambient occlusion (SSAO) on both the NVIDIA and ATIgraphics cards. The game was patched with update v1.2, which was themost current patch.
Benchmark Results: Tom Clancy's H.A.W.X. was the only benchmark we used that showed the Radeon HD 5670 video card with the 512MB frame buffer performed slower than the 1GB version. We ran the benchmark a dozen times and the Radeon HD 5670 512MB GDDR5 graphics card had a frame rate of 8-9FPS with an overall average of 9FPS. The 1GB version of the Radeon HD 5670 did much better at a screen resolution of 1920x1200, but the cards were equal at 1280x1024.
