Does Composite require full 3D acceleration? I don't think so. |
| 20 |
The "radeon" OSS drivers allow for basic 3D (yes, quite suboptimal, but |
| 21 |
enough for my purposes) |
| 22 |
|
| 23 |
The wiki says that for the ATI 9200 the "radeon" driver should allow a |
| 24 |
good composite experience: |
| 25 |
"You can get hardware accelled Render (EXA) for 9200 and below, using |
| 26 |
X.org 7.0 driver 'radeon', thus making Composite ridiculously fast and |
| 27 |
even overcome NVidia cards, since they don't support EXA yet." |
| 28 |
|
| 29 |
In fact, once tweaking xorg.conf for performance, composite works fast |
| 30 |
and quite well, apart from the occasional xorg CPU problem of my |
| 31 |
original mail. It seems more like a bug, however. |

I guess it depends from your card. ATI cards below 9200 are much better |
| 36 |
supported by "radeon" than newer cards. Until I can, I would prefer to |
| 37 |
stick with the OSS drivers. |
