Make sure you're using a patched version of the 32 bit libraries too. I managed
to play almost 3 hours in a row in a full server and in different maps without
issues at all.

These are the packages that I'm using:

* linux 4.8.12-2
* linux-firmware 20161005.9c71af9-1

* mesa-git 13.1.0_devel.87233.bd56de8-1
* lib32-mesa-git 13.1.0_devel.87233.bd56de8-1

* llvm-svn 4.0.0svn_r289147-1
* lib32-llvm-svn 4.0.0svn_r289117-1
