[Temporary] Need assistance getting my HDRP / PC game to reach 60 fps

I need a little help getting my game to reach 60fps. Currently it gets between 15 and 30 fps. I've tried various suggestions from searching Google but nothing seems to improve the fps. The profiler says my scripts should be getting between 150 and 60 fps, but the graphics rendering is 30 fps or below.

I currently don't have a website but here's a link to my game's Steam Store page so you can see the game in the videos.
