hmm… a max fps cause a lag ? I’am not sure about, thought not.
Lots of users dont like Vsync, and you can simulate that in the way that you set a max-fps-limit which is 3-5fps lower ( its a bit try out ) than your monitors fps. This works like a Vsync, but without the small lag vsync can cause.
here we should collect more informations. I would understand that with FrameGen the in-game setting may be have an issue, but at least enable that in nvidia control center should allways work. I never noticed a “lag” with vsync, but if so, then users can try the mentioned max-fps-trick
