Damn this is pretty interesting. Everyone either runs it on Off/Minimum, or Max/Max+Custom Shaders. Everything in between hardly gets touched and I assume it's because Low/Medium/Etc. don't look good enough for the FPS sacrifice that comes along with it. Also this poll will be really helpful for map/gamemode creators in the future. That way they can make sure what they've got looks good with no shaders and max shaders.
