View Full Version : multisampling and RTT

Is it correct that it isn't possible to have multisampling when rendering to texture with pbuffer (on 9800 class HW at least)? and the solution is to render to the normal buffer and then copytexsub to a texture?

Just out of curiosity, do any of the newer cards support it? It feels a bit annoying with an extra copy for an "effect" that seems like common practice nowadays.

What board are you talking about?
AFAIK there's not problem getting a pbuffer capable of multisampling using NV hardware.

I remember this was an issue on 3DLabs boards however. After complaining and spending some time with them, I recall them solving the problem.
