When playing the game in fullscreen and borderless mode the game is capped at 60fps (but the engine shows 200fps) and my monitor OSD shows that it is only being updated at 60Hz. This includes after I close the game and go back to the desktop, my display adapter settings show the refresh rate at 60Hz. However, when I play in windowed mode, there is no cap on the fps, and I can get the engine to go to a full 200fps while my monitor says that it is showing 165fps. I've disabled, enabled, and tried every single pairing of options in both Radeon Software and in-game. In-game settings I've tried: V-sync, windowed, fullscreen, borderless. Radeon Software settings I've tried: Radeon Enhanced Sync off and on, Freesync off and on, Wait for Vertical Refresh always on/off and on/off unless specified by application. I've never had this issue with any other game, and all other games run at the full fps of my monitor or close to it in fullscreen mode.

I believe it's an issue with Vulkan, because changing the API to OpenGL 4.5 allows fullscreen to run up to 90fps. The reason why I don't just use OpenGL 4.5 and call it a day is that I'm getting less than half the fps that I get when compared to running Vulkan in windowed mode. Plus, no matter what graphics settings I use, even dropping down to Medium quality, my fps don't go above 90ish.
Does anyone know of any fixes that I can try to get Vulkan to play nicely in Fullscreen mode?
Attached are images of my settings both in game and also in Radeon Software/windows desktop:
The first 7 images are screenshots of settings and display settings (display settings I haven't touched) when using windowed mode. The last image is the automatic setting when running the game in fullscreen mode.
