Performance in Simulators
IL-2 Sturmovik: Aces in the Sky
This game is rich in pixel shaders and large textures. The last thing is typical for any flight simulator, and we also know that complex textures are a weak point of the RADEON X700. There’s a small difference between the X700 XT and the X700 PRO, but these two cards are both far behind the GeForce 6600 GT which has no problems with texturing and relies on a better optimized OpenGL driver.
Using FSAA and anisotropic filtering doesn’t change anything. The GeForce 6600 GT remains unrivalled in this game, losing only to the solutions of the higher class like GeForce 6800 GT or RADEON X800 XL.
