The new SmoothVision anti-aliasing is not enabled in the current set of drivers. Instead, they employ the slower SuperSampling method. For this reason, the results we obtained here should be considered preliminary only.
The Direct3D results are an unexpected surprise! Despite the R8500's SuperSampling handicap (or, let's say, its yet-to-be-implemented-SmoothVision), the Ti500 is slightly slower in Direct3D! Although previous tests have shown Nvidia's Direct 3D FSAA implementation to be a performance killer, in this case it is the Radeon that cannot keep up with the Ti500 in OpenGL. 4xFSAA becomes impossible on the R8500 starting at 1024x768-32.
