Gl Arb Framebuffer Object Drivers For Mac
Why can't the ARB enforce FBOs to allow mixed formats, dimensions and components - like the EXTMixedFrameBufferFormats extension on nVidia Geforce 8. Currently, the ARBFrameBufferObject does not enforce the hw vendors to support mixed formats. ATI Radeon 4850, for example, does not support a FBO with both 16-bit float and 8-bit texture attachments. Without this unified approach, we are no better off with ARBFBO than the older EXTFBO since we still have a convoluted and fragmented code path with limited choices for FBO targets (aside from the integration of Mipmap generate,blit and multisample). I'd like the next release of GL (GL 3.2) to enforce this requiement for next generation h/w such as Geforce 8 onwards. Legacy h/w is really going to be running GL 3.x native apps anyway.
Where appropriate, relax some of the constraints expressed by previous FBO-related extensions. In particular the requirement of matching attachment dimensions and component sizes has been relaxed, to allow implementations the freedom to support more flexible usages where possible. At least for me ATI HD2400 with latest drivers supports different dimension attachements.
Jan 29, 2011 Since we had made bad experiences with OpenGL drivers in the past decades, we have a setting in the software to control this behavior. You have to go to 'Settings' and tag 'Use hardware acceleration' and restart the program. GL ARB FRAMEBUFFER OBJECT DRIVER FOR MAC DOWNLOAD - FBO itself does not have any image storage buffer in it.

I've not used it in actual rendering, but just now tried to attach RGBA8 + RGB10A2 and also RGBA8 + RGBA16F - works fine, framebuffer status is reported as complete.

I've not used it in actual rendering, but just now tried to attach RGBA8 + RGB10A2 and also RGBA8 + RGBA16F - works fine, framebuffer status is reported as complete. I tried with a small program that uses a 32 bits depth texture and a 16 bits RGBA texture. While the one is used for depth attachment and the other for a color attachment, this works perfectly fine (Ati 4870, drivers 9.4 and 9.5 at least).

Haven't tried attaching multiple different color attachments.
