v sync on or off?

[Vex Hilarius]

Ive been playing new vegas fine for a while with vsync on with utlra settings. Have not had a major crash or anything severe so far but theres been stutters occasionally. Will turning vsync off fix that?

[Haxel Haze]

no, but i reccomend turning it off anyways
just get NVAC and NVSR
look in the pinned threads in this forum

There will always be a certain amount of stuttering with any Bethesda open world game, it's just how the game engine works. The best that you can do is reduce it, and turning off Vsync isn't going to help with that.

So what does turning vsync off do exactly?

[Belanos]

Nothing really. It used to give you a bit more performance, but with today's video cards it doesn't really make that much of a difference whether it's on or not as far as that goes. You're much better off just leaving it on since you can avoid screen tearing.

oh ok well thanks for the help both of you.

Sorry to necro this post but the poor explanation of how V-sync works just irked me. V-sync limits the fps your game will run at to prevent screen tearing (those weird lines you see when you look up and down real fast on some games). Most monitors and tv's are only capapble of showing 59-60fps (or 59Hz-60Hz refresh rate) so V-sync shackles games to a 60fps limit to keep this from happening. If the game is running at too many fps the screen will start tearing during fast motions becasue it can't handle it. So disabling V-sync will disable the game's fps limit.

Keep in mind that games with built-in V-sync without an option to turn it off (Guitar Hero, Fallout 4, etc) were meant to run with it on and forcing it off with NVIDIA control panel or something similar can REALLY screw up your game. For example Fallout 4 will become totally unplayable because it pretty much runs like it's in fast forward without it. So make a save or backup whatever you change before messing with settings the game doesn't allow you to mess with by itself.

Also limiting FPS can actually improve performance in some cases as it frees up processes for your GPU.

Ironic. Your understanding of tearing and how Vsync affects it is off. If it's disabled, you're getting tearing no matter what. 60, 6, 666 FPS, it doesn't matter. The frame buffer is dumping incomplete frames to your monitor as soon as possible. Vsync forces the frame buffer to complete one before sending it off.

4, or more like every Gamebryo title after Morrowind, is a badly coded piece of crap that still uses the ancient "game logic is tied to framerate" thing. Take note that these games are designed with consoles in mind.
