Web14 Sep 2024 · My focus is on the percentage of texture stalls, L1 and L2 fetch misses. … WebAfter generating the iFFTs, we generate heightmap normals, compute the Jacobian, and various other things, before mipmapping the textures. Using FP16 FFTs for bandwidth savings and performance Using a FP16 FFT instead of FP32 FFT works well in this sample and this saves lots of extra bandwidth and computation in the FFT implementation.

WebIf a texture fetch is taking too long, it’s likely that a lower resolution version, or Mip Map, is still available in cache and can fill in the gap. Mip maps are the lodding of textures, where the texture density is reduced, normally, by the further away from the camera you get. They are often auto-generated on import and run by default.
