Per pixel lighting

I see people mention this stuff all the time on some 3d websites… usually with D3D. Does OpenGL has something like this?? Vertex lighting isn’t that good, and heavy tesselating is a performance hit… are there any extensions on this? maybe from nvidia? what’s the story?

can a moderator pls close this thread as there is another just like it by same author which has replies.
