PhoboPT.1804

After i checked the DX11 beta every-time i open the game my resolution is reseted. I have 2 monitors, one 1920*1080 and another 2560*1080. I change the resolution and everything works fine but when i close and load the game i have to change the resolution. It´s like the game don't save my settings. If i don't use the dx11 it works perfectly fine. It's very annoying having to do the same thing every time i want to play
