Greetings, I´m having problems with 1080p resolution, it keep the frames locked at 30 FPS, while every other resolution keeps it at 60 FPS
Oh odd. It must be selecting the wrong resolution in the list. (Each refresh rate is technically a different resolution. The game grabs the first resolution listed regardless of the refresh rate. Usually this is 60hz or 59.9hz, your system must be reporting 30hz first!)
I'll look into this further, it may take a few days though!
I've looked into this more, and it doesn't seem like it's something I can fix. Apologies! There are some parts of it locked behind the engine.
What you might be able to do is create a custom resolution. You could make it 1920x1079 for example. Just make sure the refresh rate is set to 60hz and it might work! Then simply select that resolution in-game or in the launcher. (You don't have to set your desktop resolution to it!)
Here's some guides that might help!
