No Supersampling?



I tried improving the quality of the output of a QCRenderer by enabling supersampling in the OpenGL context used by the renderer:

        [...]
        NSOpenGLPFASampleBuffers, (NSOpenGLPixelFormatAttribute) 1,
        NSOpenGLPFASamples, (NSOpenGLPixelFormatAttribute) 4,
        [...]

There does not seem to be any visible difference in the quality (only tried on a 6800 Ultra). Am I doing anything wrong? What would be the best approach for improving the anti-aliasing of QC graphics? (please consider that I have already tried the obvious routes, such as enabling the Core Image option in my Billboard patches).

Right now, it feels like the only way to make things smoother is by creating a really large PBuffer, rendering everything there, then use it as a texture to scale back down to the desired size. That defeats the purpose of the FSAA features of modern graphics accelerators though...

Thx
Gabe
