View Full Version : ATI & FBO & depth buffer & stencil buffer

02-13-2008, 03:44 AM
Is it possible on ATI hardware to use a FBO with a depth and a stencil buffer (beside one color buffer)?

GL_EXT_packed_depth_stencil seems not to be supported on ATI hardware. But trying to use 2 separate buffers for depth and stencil, I get GL_FRAMEBUFFER_UNSUPPORTED_EXT...

BTW, on NVidia I use the GL_EXT_packed_depth_stencil extension without any problems...

It's not a hardware thing, it's a driver thing; in Vista GL_EXT_packed_depth_stencil is indeed exposed (although I can't speak for how well it works and have since switched to NV hardware)

GL_EXT_packed_depth_stencil should be supported on ATI with latest drivers. (cat 8.1) I think I have used it with no problems.

OK, after an driver update to 8.1 the GL_EXT_packed_depth_stencil extension is also present on my X800. :-)
