Performance in Real-Time Strategies

Perimeter

This strategy game uses all versions of pixel and vertex shaders up to 2.0. The game features dynamic landscape, and all military vehicles and buildings cast very realistic shadows. As a result, the game requires a lot from the graphics subsystem, especially from the pixel shader performance.

When ATI designed its new graphics architecture, they focused primarily on increasing the pixel shader performance as much as possible, that is why RADEON X1800 XT and RADEON X1800 XL work so well in this game. The top model is so fast that you can enjoy this game even with enabled full-screen anti-aliasing. RADEON X1800 XL, of course, performs slower, but it is still enough to surpass GeForce 7800 GTX. The only exception is 1600x1200 resolution with enabled FSAA: here RADEON X1800 XL seems to be slowed down by its relatively slow memory. However, due to efficient the Ring Bus architecture it only loses 1fps to GeForce 7800 GTX.
