How to reproduce:

1. Have a profile and remove your current etconfig.cfg
2. Now without a config go and set all your preferred settings
3. Join a local game and see that some of the settings haven't been saved

Alright there are a couple of screenshots to show the situation. settings0 is the result for some of the settings not being saved in the 'View' menu. I left font sliders and automap zoom alone in this case.

Also I turned of Muzzle Flash before joining a game, which made it to be on after joining a server.
