You have to enable compositing yourself in System Settings. |

KMS means you're using DRI2 now, which results in a VSync'ed OpenGL |
| 12 |
rendering. Though I'd expect 60FPS because of VSync, not 50 :-P |

One other thing you should do is to enable the "gallium" USE flag and |
| 15 |
re-emerge Mesa. Then switch to the Gallium driver using: |
| 16 |
|
| 17 |
eselect mesa r300 gallium |
| 18 |
|
| 19 |
Because that driver is the recommended one for your hardware (R300). |

The classic driver should be avoided. |
