1) If you can make use of the fixed function pipeline, use it!

I'm expecting somebody more knowledgeable than me to disagree with this...

I meant completely rely on Fixed function pipeline.

If you game has a feature set that can use only the fixed function pipeline, you think there is a chance that we can improve the performance by using our own shaders which do stuff better than what the video card manufactures do? It might be possible but I think it is highly unlikey. Your time will be better spent in coding a better texture manager etc.

What is profiling?

This link about Performance Analysis might be useful.

Thanks for the replies!

I can see all of you agree on profiling as a guide to optimization so what tools do you use to profile your shaders? Can you recommend any for Cg?

one word:
NVShaderPerf.
