I discovered a way to make G-Sync work with Skyrim. I have been testing it for the last few days, and so far so good. It runs much better than using a frame rate limiter like I was before. Hopefully it will keep the physics engine from going insane due to the higher frame rates. Like I said, so far it has been fine.
Turn off Vsync in your video card options.
In Skyrim.ini add the appropriate line for your video card's refresh rate:
[HAVOK]
fMaxTime=0.0333 is for 30fps
fMaxTime=0.0166 is for 60fps
fMaxTime=0.0133 is for 75fps
fMaxTime=0.0111 is for 90fps
fMaxTime=0.0083 is for 120fps
fMaxTime=0.0069 is for 144fps
fMaxTime=0.0042 is for 240fps+
Also in Skyrim.ini and SkyrimPrefs.ini add or edit the appropriate line to turn off V-Sync:
[Display]
iVSyncPresentInterval=0 for Special Edition
iPresentInterval=0 for Original edition
Since this works on Skyrim, there is every reason to believe it will work on Oblivion, Fallout 3, New Vegas, and Fallout 4 as well. I have not tried it with them yet, but they all use the same game engine, just evolved with each generation of game.
I can now confirm that this does work on Fallout 3, New Vegas, and Oblivion. I just tried it on all three, and I get a steady fps of 62 in each game. The fMaxTime is not necessary for them. Just turn off V-Sync in the .ini files, and force it in the Nvidia Control Panel.
