Everything appears normal and framerate is about as expected, but other players appear black except for shoulder armor, hair and weapons. It is really rather strange. I don't know if this is a graphics driver issue or something else, but here are my specs.
Memory: 1.9g
Processor: Intel® Pentium(R) Dual CPU T3400 @ 2.16GHz × 2
Graphics: Mobile Intel® GM45 Express Chipset x86/MMX/SSE2
I am using Ubuntu 12.1 32-bit
It is worth noting that when I was running this computer via Vista I had no graphical issues, but then my HD failed, I lost my Vista disc and decided to use Ubuntu.
