Sorry to ask, but is it possible to render offscrean buffers with antialiasing enabled? Unfortinately, I don’t have time to test this. Have anyone tried this yet?

It’s working for me. However you will need to do a copy to texture to resolve the buffer. Actually it’s working great on Nvidia, but I have some problem on ATI. I cannot enable MSAA on the pbuffer. Must be a problem with wglCreatePbufferARB since Im able to enable MSAA on the default context using wglChoosePixelFormatARB.
