not just older cards - 24bit depth is pretty much standard, and allows cool tricks like stuffing an 8 bit stencil buffer into the unused byte (see EXT_packed_depth_stencil). Also, don't use a screen mask. Also, don't use the FullScreen attribute. As a useful reminder: https://developer.apple.com/graphicsimaging/opengl/capabilities/ Note that only the Red (ATI) cards and the Grey (Software renderer) "Card" support 32 bit depth. If you're not using an ATI card, this will probably fail. -- Christopher Wright christopher_wri...@apple.com
