I think the v5 do support bump-mapping (emboss effects and such?) if so.. what good games do use this feature and work well with a p3 866mhz and a v5 5500?

As nobody seems to know anything about it, I guess bump-mapping on the voodoo4/5's is like the awesome t-buffer cinematic effects:

no standarized = no game support = useless

at least they would have included bump-mapping support on direct3D, carmageddonTDR shows no bump-mapping support. I dont doubt the hardware for it is in the voodoo cards, but again...

no standarized = no game support = useless

PETITION TO DRIVER DEVELOPERS (if any1 reading this)
Add bump-mapping to direct3D for the voodoo4/5

Well, Emboss BumpMapping I really never saw fully applied in Games I played.

Only recently, the more advanced (Dot3, Environment Mapped and Cubic Mapped) Variants of BumpMapping see some action.

Looks like at that time, Developers were going more for adding "normal" 2nd, 3rd and 4th Texture Layers containing advanced Lighting, Reflection or other Effects-Textures, instead of using classic Emboss BumpMapping.

Some of the HighRes S3TC Textures of Unreal Tournament do have a BumpMapping-style look to them, although I'm not 100% sure if it's not just a more detailled Deco Layer = normal Texture (actually seems that way).
