Its impossible to speculate whether it would or would not because it can't. I imagine if it were capable of doing so. Then Ya I would predict a small performance boost.

I should clarify what Pixel Shader texture embossing is (I'm not meaning to insult your intelligence on the matter, But some people might be interested)

its Using the Pixel Shader to do the texture mapping on a surfaces, I used PSX Emulation, Like most feasible emulation right now. Its Limited to 16 bit merely as an example.

It could be done to sharpen the textures without stressing Bandwith, Rather than GPU fill rate,

Its rather a unique effect tho

Its not more important mind you either, But I believe a higher level of configurability at the users end is,

Maybe one user wants to turn up a specific setting, Then turn down another, The higher and more configurable a user options are, The more they can sacrafice something to get something else later,

Now this might not matter for PSX emulation, But the upcoming dreamcast emulation for Icarus might be able to benefit from this ect,

It also has possibilities elsewhere, Texture embossing is a DirectX 9.0 feature btw...
