i am new in compute shader programming. Unfortunately, there are no good book and other material on this topic, so i have lots of questions.
Because Compute shader uses lots of threads, is it possible to use compute shader for post effect instead of rendering quad screen ? will be this technique faster, since it's multithreaded ?
I tried few demos, where they using thread per pixel, usually 16x16 threads per group. This configuration seems to be fastest, why ? if i try 32x32 or 8x8 .. or different threads, it's always slower.
Could you recommend me some good website or book for Compute shaders ? ( mainly DirectCompute ).
Thank you very much
