I know it's old but 'man radeon' tells US that RV630 is supported. I possibly can geht a 7950.

It's a playing track. What about the seconds delayed opening of the plugins' window? To me it seems Ardour gets more and more unresponsive by increasing number of active plugins. It's a project with 7 tracks and 3 busses with one or plugins each.

I don't hear a glitch. Just seeing a fast increasing counter of xruns.
