Performance in Simulators
IL-2 Sturmovik: Aces in the Sky
IL-2 isn’t a game the RADEON X800 XL can show its best qualities in. It uses the OpenGL API and has an evident liking towards NVIDIA’s cards. The GeForce 6800 GT is as much as 40% ahead in the highest resolution, and the SLI configuration of two GeForce 6600 GT is 50% ahead. The latter produces image artefacts, though, so you’ll hardly want to play it.
The performance gap between the GeForce 6800 GT and the RADEON X800 XL is bigger in the “eye candy” mode, although ATI cards are generally better at doing full-screen antialiasing and aniso-filtering.
