When I change settings from there and run the game it says to update to directx9 and delete the file T.T is there a way i can change settings from the file ?
Moved to the correct section.
What are you trying to change exactly? I don't recommend touching the files in the UGG folder directly in case the anti-cheat or launcher won't let you open GunZ.
If it's anything texture related or anything or the sort that can be accessed via the in-game settings, I would advise you to try that first.
Please respond to @Eun and what he has asked you or your thread will be closed due to inactivity within 48 hours.
Unfortunately you can't edit Gunz files, by attempting to do so you will receive an automatic temporarily ban by the system.
