Description Pavel Ondračka 2011-04-15 12:02:55 UTC

When HDR is used fires from torches in Unigine an various other light sources are rendered checkered instead of "smooth pixels". This is also visible with sun in Unigine Tropics.

GPU: RV530
Mesa: 41b38bd21c1031e65799c888a97d8a0c14ea2aaa with --enable-texture-float
Kernel: 2.6.38.2

Comment 1 Marek Olšák 2011-06-08 17:04:53 UTC

The reason it's not smooth is that R500 cannot filter float textures. There is nothing I can do about it, it's a hardware limitation. Closing.
