Doki dropped new settings video, pretty good. picrel caught my attention as I've not heard of these Windows settings. idk if it's placebo or real af, but he swears by "Disable full-screen optimizations," which is interesting. I'll test it out later. As he rightly mentions for several settings, you gotta A/B test it on your own PC, sometimes shit varies.
Regarding Nvidia Reflex I agree with him. Simply On is a better setting than On + Boost. I've gone back and forth on various games with this setting and On feels smoother with less GPU strain.
