Bug #: 28901
           Summary: Slower than expected performance in Jedi Academy
                    Multiplayer (AMD Radeon card)

I'm getting much lower performance than expected on Jedi Academy on this
particular system. I'm using the official catalyst drivers on Ubuntu 11.04, and
native games run fine (Urban Terror at a constant 130 FPS). But on Jedi
Academy, there's a slight "jitter" in the graphics and the in-game FPS meter
jumps between 80 and 110 a lot. When there are more than 3 players on a server
the performance impact is much more noticeable. Even though the FPS shows a
good rate, the game doesn't feel smooth. Some maps feel much worse than others.
On my Windows 7 partition, I get a very smooth experience with a constant 300
FPS ingame. Not a single hitch.
An old laptop of mine runs the game with lower FPS, but with flawless gameplay.
With an integrated, entry level, Nvidia graphics card on the laptop I get a
consistent 100 FPS in Wine and everything performs exactly as it would in
Windows.
I am sure this issue is most likely related to the AMD graphics card. Still, it
would be great if this issue were addressed because a game that normally runs
flawlessly in Wine just runs sub-optimally.
