Performance in RPG
The current version of this game doesn’t support FSAA, so we had to use anisotropic filtering only.
The game makes wide use of shader-based special effects, and the 24 pixel processors of the Radeon X1650 XT card lift it up to the same level with the GeForce 7900 GS. Without full-screen antialiasing, the 256-bit memory bus of the Nvidia card doesn’t give it any advantage.
The current version of Gothic 3 is a highly demanding application. The mainstream graphics cards run it too slow. You can’t have a smooth gameplay on them.
Neverwinter Nights 2
The game looks best with enabled HDR, so we benchmarked the cards in this mode. Moreover, the Nvidia GeForce 7 series cannot use FP HDR together with FSAA.
The Radeon X1650 XT is slower than the GeForce 7600 GT in 1280x1024, but then overtakes it in 1600x1200 and leaves it behind in 1920x1200. The speeds are low, however. Moreover, the reflection and refraction effects do not work on Radeon X1000 cards in the current version of the game.
