It's a forum dedicated to Linux/FreeBSD/GNU benchmarking and 3D-applications.
This subforum is only used for Linux/FreeBSD/GNU 3D-applications using a specific set of hardware and software that's specifically designed for gaming or rendering other forms of home entertainment.
Unless you're talking about the workstation stuff but almost nobody does here, so effectively it is a gaming forum.
Not in the direct sense. This isn't a forum about discussing games, but rather discussing how to make them work.
