Refresh of brightness bug. Here´s the solution.

[ETc|#.Jay.#]

If you have problems with changing brightness ingame and its not refreshing anymore, you should look in your etconfig.cfg/autoexec.cfg or other configs. When there are over 1000 cvars or more, this can make alot of mysterios bugs. You should cleanup your config from useless cvars. For example you can delete all cvars wich begin with b_ etj_ sv_ g_ vote_allow pb_ they are not needed for nitmod. You should have not more than 600 cvars in your cfg. arround 500 are standart.

To delete them quickly, you can use notepad++ https://notepad-plus-plus.org/downloads/

Thats all.
