I think someone told me once (grain of salt) that AMD/ATI had superior open source drivers.

I presume that when dealing with 2D, the open source prevails and functions much better, and unfortunatly what I posted in the original post about FPS drop from upgrading to closed-source might have been false information, as my recalled last time of playing Disgae only resulted in crackles and to my knowledge 60 FPS in which I was indeed using closed-source, but then again I think I might have updated my AMD drivers a while after that. I think I could run some benchmarks on current, downgrade and open-source.

Would anyone know any spec-heavy games for examples for both major 3D usage and only 2D usage?
EDIT: A mix between two would be great as well.
