As the title states, I got a noticeable performance increase with the Ultimate Engine Tweaks mod, it's on nexus mods. My rig is pretty basic, Ryzen 5 5600G, 32GB ram, 3060 (12GB). Was getting like 20-30 fps on average all low settings 1440p, now I'm getting like 40-50 fps. I just thought I'd post here about it in case someone else (like me) gets frustrated because of low fps. Ok have a good one fellas, I gotta get back to shooting bandits.
