I can confirm Portal 2 (Source), Jagged Alliance: Flashback (Unity) and XCOM:
Enemy Unknown (Unreal Engine 3) as working, though the performance in XCOM is
abysmal (9 FPS) and after a while you get GPU stalls (system recovered after a
short block and I could continue, but it's of course not much fun).
The other games have room to improve as well. But that was to be expected at
this point. Still, having more performance with the free driver would be really
nice. ;-)

Playing streams (live and recorded broadcasts) from Twitch with this setup is,
however, neigh impossible. With the open driver and GLAMOR acceleration, X uses
80 % CPU time on one core and the video becomes a dia show. The Flash plugin is
at 40 % CPU time (different core), but that's roughly the same as with fglrx.
(For reference: my CPU is an Intel Core i7-3770K.)

Can't say for sure. With XRender I saw a corrupted glyph almost immediately on
the first page I visited. Since switching to OpenGL as "compositing type" in
KDE's settings, I haven't seen a corrupt glyph. But it could also be
coincidence.
