this is a bit off-topic but something came to my mind regarding EMBM on geforce cards.

actually EMBM is fake reflection bump mapping.

per pixel environment mapping (=real reflection bump mapping) seems to work without problems with a6 and geforce cards! it should look even better than EMBM but the downside is that it is much slower.

this effect requires some matrix*matrix multiplications in the vertex shader. this is quite awkward to do with shader assembler and i have to figure out a way to do that first...
