ERROR|Desje35, I can't seam to see anything that can cause the resolution to be changed after a map, though you have only showed me the render settings. But I can't recall any setting with that particular behavior.

I would suggest you to delete any other profiles and configs you don't use. Sometimes there can be a config that overwrites your custom one. So try the following:

1. Delete unused profiles
2. Delete any configs you don't use. e.g. etconfig.cfg
3. Delete all profiles and create a new with your settings in a complete new config file. e.g. yourname.cfg or try put the settings in a autoexec.cfg file

Check back here if it still doesn't work.
