AMD Radeon HD 4890 On Linux
Prey has been around on Windows for years, but it was only last year that the Linux client was released. Prey uses the id Tech 4 engine with some modifications and is one of the more demanding Linux-native games. The ASUS Radeon HD 4890 at stock speeds ended up being 16% faster than the Radeon HD 4870.
We ran Prey again at 2560 x 1600, but this time enabled 24x edge-detect anti-aliasing and 8x anisotropic filtering through the AMD Catalyst Control Center. When stepping up the AA/AF, the Radeon HD 4890 ran 18% faster than the Radeon HD 4870.
