Good day, friends! I've been working on optimizing the build for two days now and decided to switch to Unity URP. This will reduce the quality of the lighting (there's nothing that can be done about it, URP's default lighting is weaker), but it should significantly improve performance. The process is not complicated, but it's long and tedious — as of now, there's no fully functional method to automatically (or even semi-automatically) switch from HDRP to URP. I'll try to complete the transition as quickly as possible (I even took some time off work to do this).
