    APPALLING ACCUMULATION BUFFER PERFORMANCE

    Can anyone help?

    I have a GeForce3, running under OS X 10.1, just installed, so drivers should be latest and greatest, but my accumulation buffer performance is abysmal. It appears to be dropping back to software to do accumulation buffering, I see 1/100th second frame renders, then approaching 1/2 sec to do a glAccum. It's a Cocoa app, the OpenGL context has been set up to use accelerated, 8888 rgba, 16x4 accumulation buffer. It's bloody annoying.

    Yep. No hardware accumulation buffer support in mac os 9 or X. Just read that on apples site. And this is regardless of whether the context is accelerated or not.
