I don't bother doing the typical -3 of max because 157FPS is pretty hard to maintain at 3840x1600, even with a 3080TI heavily OC'd. I'm currently testing GSync + VSync permanently enabled in the NVCP globally I've always ran GSync + Vsync OFF with a framerate cap of 117 (so currently, 117fps max on a 160Hz monitor) but I've been reading there have been some changes to the way GSync acts with VSync going all the way back to 2015. If you're not able to hold double your max refresh rate, typically Adaptive will be the setting that will incur the lowest input lag and remove the most tearing. Fast is really used for games that run extremely high framerates (lets say, CSGO where I would be playing at 400FPS, so half it down to a very consistent locked 200FPS).

Adaptive VSync is usually the best choice (as theshadowcult said). Hell, you never told us if you used ultra high quality (texture quality. To be honest I never even found doom 3 to be scary since I have a big dick since birth. I have read quite a few reviews of Doom3, all stating that the graphics are. I would test out the different settings available to you. Answer (1 of 2): I just got that game today Using my system as a baseline : Ry4.0Ghz GTX 1660 Ti 16GB of DDR4 3200 With these specifications, Im able to run doom at Ultra, 1080p with an average FPS of 68. Ultra Quality Settings are Dumb PC Gaming. to support it on ultra settings until the next generation of graphics cards comes out.

I owed you one for the help with the Win11 context menus I almost never make changes in the nV CP, so I forgot you could make app/game-specific profiles.
