U're TNT2 owner, right? GL_EXT_texture_lod_bias was introduced in 5.xx and it was supported by GF boards only. Probably NVIDIA had implemented this extension for TNT/TNT2 in Detonator 12.xx, but it's new info for me.

Yes, I have a TNT2. 
 
As for 12.xx i.m starting to give more credit to nvidia. I was thinking that all their effort goes to the new GF3. Well, as opposed to the 10.80 and 11.01 performance for TNT2 in D3d is only 5% lower then 6.50, as opposed to the 25-30% hit in the 10.80 or 11.01 and in opengl resuults are mixed, generally lower with 3-4% but with a great increase in Tirtanium of 16%. 
However it seems that in this version blt with color key is entirely softare, which may seem that other direct draw optimizations are not implemented yet, at least for the TNT.
