Performance in RPG
The current version of the game doesn’t support FSAA, so we performed the test with anisotropic filtering only.
This game is not compatible with CrossFire, either: the min speed of the CrossFire system is lower than that of the single Radeon HD 2900 XT. As opposed to Splinter Cell, the game obviously prefers Nvidia’s GPUs, and products developed at ATI Technologies don’t provide an acceptable speed in high resolutions.
Neverwinter Nights 2
The current version of the game still doesn’t support HDR normally, so we perform the test in the eye candy mode with 4x FSAA.
The Radeon HD 2900 XT 1GB CrossFire behaves oddly here. Its performance is roughly equal to the GeForce 8800 GTS in resolutions up to 1920x1200, but then it seems to get a second wind in the most resource-consuming 2560x1600 resolution, outperforms the GeForce 8800 Ultra, and ensures a playable frame rate. We can’t yet explain this phenomenon.
