Your card can't accelerate 24bpp for anything more complicated than 2d source copies, only 24/32 depth with 32 bpp, so you're actually at 32bpp. Also, front, back, and depth buffers are allocated statically at startup all with the same bpp, so there are 3 buffers. So, width * height * 4 * 3 is how much you need. (These logs posted here are different from what was initially posted. I'm still curious as to what was happening previously.) -- Eric Anholt eta@lclark.edu http://people.freebsd.org/~anholt/ anholt@FreeBSD.org
