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.
