Regarding Postprocessing Shader

[LunaMoo]

Linux is free and I belive intel actually has decent drivers for linux(likely more decent that their windows ones), so possibly OGL would be faster if you're into installing another OS just to test. Otherwise just wait.

I never bothered to check before, but it seems the code for postprocessing shaders is already shared between ogl and d3d(?), so it's probably unfinished or simply doesn't have any automatic translation(which likely would be enough for most simple shaders) and would need separate hlsl shaders, not sure.
