When anisotropic filtering is selected, both NVIDIA's GeForce 6800 Ultra and ATi's Radeon X800 XT produce an image that greatly differs from the one produced by Refrast. This is a direct result of the aggressive adaptive angle-based optimization. You can see that the filter of the GeForce 6800 Ultra (without trilinear optimization) is obviously less exact around horizontal plane, while ATi's X800 optimizes at the sides of the tunnel.
