We now have 3D hardware capable of simultaneous MIP-mapping, anisotropic filtering, and antialiasing in real time, at 60 frames per second in many titles. |
It offers up to 50 percent performance improvement in ray tracing with antialiasing, as well as other feature improvements. |
Edge antialiasing only works at the edges of primitives, but jaggies can happen also at intersections of polygons. |
I was wondering if anyone can explain what it is exactly that anisotropic filtering and antialiasing do. |
The old-fashioned method of antialiasing is called super sampling. |
We believe that running at higher levels of antialiasing would generate unplayable frame rates, so we didn't test with higher settings. |
