Serious Sam: SE, Unreal Tournament 2003
Serious Sam: SE
Vendor: Croteam - (Website)API: DirectX 8.0
Pixel Shader Version Supported: No pixel shaders
More memory bandwidth scaling between the two FX 5700s with the Radeon bringing up the rear. Again, it's OpenGL performance isn't as good as it could be, with the performance lagging ever so slightly.
Unreal Tournament 2003
Vendor: Epic - (Website)API: DX8.0
Pixel Shader Version Supported: PS1.1, some limited PS1.4 shaders to render terrain in less passes
Memory size again has an effect at 1600x1200 with the Ultra/980 able to close the gap on the P Turbo. The Radeon's performance is lacklustre. With very little pixel shader action in UT2003, raw fillrate and memory bandwidth take over as the main determinents of performance.
