Can you try using the "ExaNoComposite" option? That may bring you back to
XAA/noaccel performance levels.
The reason for moving to EXA by default is that XAA simply can't support
several of the features the driver has available, like a tiled frontbuffer or
framebuffer compression. Carl, Keith and Dave have been working on the
performance problems, but they probably won't be fixed for this release.
