emboss bumpmapping shouldnt be used as a fallback (it looks very very crap) - emboss bumpmaps come at quite a speed cost as well.
better to not have bumpmaps if the card cant do them

btw i agree with daveperman on the issue, if ppl want to see bumpmaps etc then they would buy the card if not then fine but wasting a lot of time on developing something that isnt really gonna be of much use (eg like emboss bumpmaps is just stupid)

btw daveperman thats not bumpmaps

well zetzeek.. my one is not bumpmapping but perpixellighting.. including bumpmaps (i chanched them at home and so i got them much more bumpy than onlie.. but i don''t want to replace it there currently.. *bored*)

i wasnt knocking it, just saying it didnt really showoff bumpmaps.
btw in your demo none of the keys (e,d,f) worked for me. i have a gf2mx
(the ones to move the light/camera though did)
