I've been implementing a post-proc pass in my framework but I don't really know which kind of sampler filter would be most effective.

This is in regard to sampling the scene rendered texture in my post process shader, any advice on which filter type (Point, Anisotropic, Linear etc) to use and why would be very much appreciated.

Apologies if this topic has been iterated over before, couldn't find anything on it personally.

Do you want to sample a single pixel? Use point sampling, or alternatively use Load instead of Sample, which removes the need for a sampler state at all.

Do you want the weighted average of a few pixels? Use linear sampling.

Are you donig some kind of fancy optimization where you want to filter along a line? Use aniso.

Thanks a lot! I am using load now, but I also know when to use these different kinds of filtering modes now. Cheers! :D
