Hello,

Problem: Direct Rendering won\'t work with planeshift, so it runs slowly.
Distribution: Fedora Core 3 (kernel: kernel-2.6.11-1.27_FC3)
X server version: xorg-x11 6.8.2-1.FC3.13
glibc: 2.3.5-0.fc3.1
Graphics card: S3 Unichrome (unsupported in FC3, followed instructions from http://sourceforge.net/docman/display_doc.php?docid=26963&group_id=102048 to install.)

strace output:

Output in terminal:

Indirect rendering may indicate a flawed OpenGL setup if you run on a local
  X server.

With other games such as Neverwinter Nights, direct rendering works and the game runs smoothly.

Thank you.
