Hey everyone. I''m trying to find a tutorial or two or more on RISC-Assembly, which is what I''ve heard you have to learn to know how to use those shader things in D3D8. I know there is a book on it, but that I cannot afford. Thanks to anyone who can help!

Just to clarify:
There''s not one single assembly language called "RISC-Assembly". RISC is a type of architecture (it means Reduced Instruction Set Computer). It''s the opposite of CISC (Complex Instruction Set Computer). It refers to the ''ideology'' used when designing the instruction set of a computer. CISC systems have a lot of instructions (many specialized for a particular purpose etc), while a RISC architecture use a few basic instructions, and those instructions are combined to create more complex expressions. (Perhaps not such a good description.)

When they say that the vertex/pixel shaders use a RISC assembly language, it simply means that they use an assembly language with relatively few instructions. Microsoft probably has some resource about the assembly language used for shaders at msdn.microsoft.com

(the x86 architecture would be a good example of CISC)
