How to change Game Resolution without opening game?
In a bit of a quagmire currently. Was at the 2nd boss of Blood Hunt Tactical and my FPS always drops. So, I decided to lower my resolution. No big deal right? I've done it before, just to compare or if I wanted some extra FPS during a difficult fight.
Well, I set it from 1920x1080 to 800x600 and bam! I get booted to desktop, game is still "running" but it's minimized. Closed it out. Fixed desktop resolution because it was jacked up too. Reloaded game, and same thing happens.
Is there a way to set the in-game resolution so I can get back to playing what I pay for?
When it goes like that on start up
