Hello guys, If this is already asked sorry but i couldnt find anything about this problem. I changed my monitor and Graphic card i started to use everthing in 3840 x 2160 resolution. Anyway, is there a way to make your UI size bigger because i cant see or click at interface. Its too small tried to changed UI_size from settings.cfg but nothing changed. Any suggestions? mybe a hotfix update or sth else.. it should be easy.
