the problem with compiz/compiz fusion is that it needs a high level board to |
2 |
run smooth and curently. fglrx has some bugs, except for the 6+ version, |
3 |
that should be corrected in the new 8.43 release of this month. |
4 |
as for beryl, of my experience it needs at least half the resources of |
5 |
compiz. |

this is the problem of the cpufreq polling mechanism. if you lauch the |
21 |
effect when the processor is about to poll the load then you won't have |
22 |
problems of slow effects. if you want a more receptive system set the timer |
23 |
freq in the kernel to 1000 hz and then set the polling of the cpufreq to |
24 |
lower values. |

And it's not only on Beryl. I'm using XFCE with composite enabled for having |

same problem as before. by the way, beryl is destined to die, for what i've |
32 |
learned. |

OpenGL performance with this card is great as you can see with Tremulous and |

nvidia has released drivers last week or it's about to release a new driver. |
