Hi Andrew, Well, I got this not-so-useful reply from ATI: >Regarding 10-bit frame buffer support. > >The RADEON 9800 products all offer 10-bit frame buffer support. In regards >to developing with OpenGL you can refer to the Developer Relations >department. Please visit their portion of the ATI website at >http://www.ati.com/developer/index.html > > >Regards, > >Kyra Plouffe >Customer Care >ATI Technologies, Inc. >http://www.ati.com ATI seem to lump 10-bit frame buffer support under the term "Smartshader": http://ati.com/companyinfo/glossary/includes/list.html#smartshader From what I can tell, "Smartshader" has been supported in both D3D and OpenGL since the release of ATI's Catalyst 3.8 drivers: http://www2.ati.com/drivers/catalyst_38_release_notes.html#168664 This occurred back in Oct. 2003: http://www.ati.com/companyinfo/press/2003/4694.html less than a year ago. So, perhaps the 10 bit framebuffers are now supported in the OpenGL drivers. Either way, we're about to buy the card. We'll give it a try and report what we find.

This was over a year ago now, though, so times may have changed. There was a thread about this on the psychtoolbox list with myself and Jon Peirce, among others, sometime last year, if you want to read further. Cheers!
