Hi,

this is my first bug report, so feel free to point me in a different direction
if necessary please. I am getting a flawless 30+ fps on one of the tutorial
maps without any graphical glitch. However on a different map, there are heavy
texture issues. Please see: http://youtu.be/wHLVaa5aTmA 

Last few lines from dmesg after gameplay:
