I’m not affiliated with this YouTuber, but I thought this might be useful to someone else. I have a RTX 3080/Ryzen 5800x/32 GB machine and was hovering around 30-40 FPS even after turning a lot of settings down. I think I just haven’t kept up with the best combination of settings. This video got me up to an average of 70-80 FPS (except for in denser areas, where it can drop to 45).
I have an RTX 2060, undervolted and temp limit to 65C (can’t stand the fan noise). Got a stable 55-60 fps on standard high/ultra settings, no DLSS. Edit: 1080p
