Maybe I’m blind, but PBUFFERS are not supported. Please read the following carefully. If they are supported ATI is making them unusable. My only means of verifying the existance of features are the “gl*strings” I’m not going to just cross my fingers and hope for the best by starting to access extension that don’t exist.
I also took a look at the 2.9.12 drivers. I did not bother to install them however since they clearly state the following in the release notes
" PBuffer support: available only if you have an ATI FIRE GL graphics board
installed in your computer. No PBbuffer support for ATI Radeon and other
boards."
Of course maybe based upon ATI’s poor information on their website about their drivers, Can I trust them? Maybe I should just waste another hour and install them.
