DX11: Tom Clancy's HAWX 2

Tom Clancy's H.A.W.X.2 has been optimized for DX11 enabled GPUs and has a number of enhancements to not only improve performance with DX11 enabled GPUs, but also greatly improve the visual experience while taking to the skies. The game uses a hardware terrain tessellation method that allows a high number of detailed triangles to be rendered entirely on the GPU when near the terrain in question. This allows for a very low memory footprint and relies on the GPU power alone to expand the low resolution data to highly realistic detail.

The Tom Clancy's HAWX2 benchmark uses normal game content in the same conditions a player will find in the game, and allows users to evaluate the enhanced visuals that DirectX-11 tessellation adds into the game. The Tom Clancy's HAWX2 benchmark is built from exactly the same source code that's included with the retail version of the game. HAWX2's tessellation scheme uses a metric based on the length in pixels of the triangle edges. This value is currently set to 6 pixels per triangle edge, which provides an average triangle size of 18 pixels.

The end result is perhaps the best tessellation implementation seen in a game yet, providing a dramatic improvement in image quality over the non-tessellated case, and running at playable frame rates across a wide range of graphics hardware.

    I have this card, and the fan at 100 percent is very loud. How could you possibly not notice a difference between 20 percent and 100 percent fan? Only explanation is that your ambient noise levels are very high, in that case you shouldn't state the card is silent at 100 fan, because it isn't.

    Why would you ever use the fan at 100% power? Every video card fan I've ever tested is loud at that power, and equally unnecessary.
