I also have this GPU. |

I have 3 machines with Intel graphics that I run compositing on with |
| 22 |
compiz and they run fine. Like I said so long as you disable the blur |
| 23 |
plugin in compiz it's pretty solid. Actually, recently I installed KDE4 |
| 24 |
on a VM and ran KDE through XDMCP with all the compositing effects |
| 25 |
turned on and it ran smoothly as well. |

The "X was eating CPU" seems to indicate that it's not the GPU that's |
| 28 |
doing the 3D rendering but the CPU. Now if you got slow performance yet |
| 29 |
your CPU was sitting there doing nothing then I'd suspect the Intel |
| 30 |
Graphics. |
