Hello I have a question to you about some HLSL stuff.I implemented a global illumination compution with RSM and get with the cornell model and a 12*12 lightmap samples for each pixel a framerate of about 60 fps. That means I have to sample 3 textures ( diffuse/flux,position and normal, all R16G16B16A16_FLOAT format ) 144 times per pixel and that makes the computation slow.
When I don't sample the textures and give them const values ( just for a test) I get avbout 800 FPS so this is a big difference.
Now the question is how can I increase the speed of reading my textures to get a better speed ??
