Hello,

I am using DX9 and Shader Model 3.0. In my Pixel Shader files I declare textures like this:

sampler myTexture : register(s0);
sampler myTexture2 : register(s1);

Now I wonder how many sampler registers s# are available? I searched a lot but could not find a number. Thanks for help!

It's in the DirectX SDK documentation:
