Simple question: does anybody know how to enable anti-aliasing on a FP16 FBO or PBuffer on X1xxx ATI cards ? (NVidia hardware doesn't support it yet). I tried to list the supported pixel formats in a PBuffer but none of them have FP16 + AA at the same time.. Y.

Can't be done with FBO atm, there is an extensionto allow it but ATI are as yet to get it in their drivers (which is daft considering it's an advantage over NV's hardware...), spec, might be down to needing to support the blit extension as well..

I got news from ATI's devrel. They have no intention of supporting FP16+antialiasing in their current drivers, because they prefer to focus on Vista. That's pretty lame IMO: their hardware can already do it, they've been using this argument (ah, look Nvidia, we can do FP16+antialiasing) in their advertisements and marketings everywhere, and it will take a few years before Vista is well installed, but no..

That sucks, it is working in D3D (FarCry, Oblivion, SS2, etc). IIRC same thing with native R2VB support in OpenGL [flaming]
