View Full Version : 4XS AA in OpenGL?

Will NVidia ever support 4XS in OpenGL on the GeForce4? Is there a technical reason why this is not possible or is it political?

As far as I can tell, 4XS is nothing more than 2x multisampling with 2x supersampling, so you can basically do it yourself without too much trouble. The only complicated part would be to set up the pbuffer and changing the swapbuffers to a full-screen textured quad, but that's pretty simple to set up.

I don't know about the "poltics" of the situation, but I doubt that the ARB_multisample extension allows you to specify hybrid multi/supersampling. I'd/you'd have to check it out.
