DRI is hardware accelerated 3D rendering. You don't need it for music apps, |
| 2 |
but you most probably need it for your Windows games, without direct |
| 3 |
rendering you will use software rendering and get most likely get <5 fps in |
| 4 |
OpenGL games. It may be nice to have direct rendering for xine too, since |
| 5 |
xine can output its videos through OpenGL - don't know about MythTV though. |
