Benchmark Results: DirectX 11

Aliens Vs. Predator: DirectX 11 Game Performance Analyzed
By

Now, let's examine the performance when DirectX 11 enhancements are turned on.:

Indeed, Rebellion's claim of increased performance is verified here, and suddenly CrossFire seems to be working. But on closer inspection, things are a little more complex than that. It looks like the cards with the highest compute performance, such as the Radeon HD 5830 and above, get a performance boost from DirectX 11, while the Radeon HD 5770 holds its ground and the slower cards actually lose some traction.

The good news is that, up to 1680x1050, some low-end cards get a sizable minimum frame rate boost from DirectX 11, despite the implemented DX11 features. At 1920x1080 and above, performance is similar to DirectX 9, but two Radeon HD 5850s in CrossFire can easily handle 2560x1600. A single Radeon HD 5870 does the job at this resolution, too, though not as smoothly.
