Performance in Simulators
Radeon X1000 series cards do not support vertex texturing, so they can’t use the appropriate technology to render the water surface with the highest quality in this game. This is only available on Nvidia GeForce 7 GPUs.
The Radeon X1650 XT is no match to the GeForce 7600 GT in both performance and image quality here because the game is optimized for Nvidia’s architecture. Anyway, you have to lower the resolution and/or the level of detail to play the game with comfort.
If you like this very beautiful space simulator, you can now run it on a mainstream card that provides the performance of a GeForce 7900 GS at a lower price. The new Radeon is limited to 1280x1024, but you can’t expect more from a graphics card of its class.
