2x AA at 1024 x 768 x 32bpp in Unreal Tournament 2003. The partial is magnified to 400% in order to show the effect of anti aliasing. At 100%, anti aliasing effects are barely visible.

Anti Aliasing
Maybe you remember from the third page of this review that the Xabre600 offers 1x, 2x and 4x blur and oversampling whatever that means. By definition, 1x blur does not make much sense unless it is used to mean "pixel radius" in which case, 1 x will translate into roughly a 4x multisampling paradigm. The Xabre600 does not appear to pertain to the same terminology. In fact, we did not see any 1x option at all in the control panels, 2x, 3 x and 4 x were the only options.
The 2 x option appears to use supersampling across edges and it is not very efficient. That means that screenshots have to be blown up to 400% enlargement to even see that there is any form of antialiasing going on. In most games, the jagged edges and line crawling persists with the 2 x mode selected and, in terms of visual quality, it is virtually indistinguishable from no antialiasing at all. Fortunately, though, we did not see any performance degradation beyond a hardly reproducible 1-2% either.

At 4x AA, things look much better, edge crawling is largely reduced and overall the diagonals look rather smooth. The insert shows a 200% magnfication of the head area and the quality is fair enough.
