I have been experiencing issues when I use the resolution slider in your mod to play the game above my monitors native resolution using Nvidia's DSR.
I've had problems where my viewing angle would move on it's own when I move the mouse a little bit in a single direction.
I also had an issue where the menu's inputs would not get scaled down along with the menu's button textures.
When I set the resolution to 3840x2160, I could only move my mouse left and up.
Other then that, the game runs very smoothly at these resolutions.
