Thanks for the advice. Sadly it did not fix my problem.

Is it possibly to changes screen-resolution anywhere in the games config files, when running full screen? Because then I could just set it to run lower resolution by default.

When I run the game at 3840x2160 the coal on the minimap is very hard to see, and if I move around it start to flash. If I lower my resolution to 1920x1080 the problem goes away.

Is there anything I can do to run the game at my monitors native resolution?
