Both Fedora and CentOS support GL out of the box. However you do have to be careful about your grahpics hardware in order to get hardware-accelerated 3D.

For most newer cards, however, you'll need to use closed-source drivers from ATI or nvidia. -- Joshua Baker-LePain QB3 Shared Cluster Sysadmin UCSF
