Left 4 Dead 2 on Linux Mint
============================
Out of the box Left 4 Dead 2 will not run correctly on Linux Mint.
To resolve this we will want to remove steam from the repository and install it directly from steam.

Install Left 4 Dead 2.

Steam on Linux downloads Vulkan Shaders and stores them in `/tmp.` Now ever time the computer reboots these have to re-download (~4.3 Gb). To stop this we need to disable shader pre-caching. Go to `steam` - `settings` - `Downloads` - and disable `Enable Shader pre-caching`.

Secondly, some systems will experience crashing when loading into levels. We can prevent this by setting the launch options below.
From steam right click `Left 4 Dead 2` and select `Properties` - `General` - `Launch Options`. ::
