Hey Anticleric, regarding the "Modified OpenVR DLL with AMD FidelityFX SuperResolution Upscaler" I mentioned before, for the plugins folder I replaced openvr_api.dll and added openvr_mod (downloaded https://github.com/fholger/openvr_fsr/releases/tag/fsr_v1.1), and then in openvr_mod.cfg I set renderscale to 0.50 and went from 20fps in the diner area up to 60fps (using an rtx 2080, Ryzen 5600X @ 4.6Ghz). I think this could potentially be a neat feature to add for settings to massively improve performance for those who complain. I like the simplicity of this openvr_mod.cfg file, as this can be changed very easily, and used with many other games as well. Just thought I'd share in case it was useful for anyone else.
I think if I set balanced then the game will look much better with improved performance. Still testing different settings in the openvr_mod.cfg.
Edit: I realized by activating Synchronous Spacewarp (SSW) in Virtual Desktop + using the above mod (I set renderscale to balanced instead) = basically gameplay that feels like solid 90fps the entire time. I'm enjoying the game even more than before because I don't get sick anymore from low framerates.
