Camera jitter/stutter fix (caused by vsync)

[Machian]

Using the game engine vsync (ipresentinterval=1) and nvidia driver vsync causes the camera jitter/stutter like crazy when i strafe and turn camera.
I fixed this problem by setting ipresentinterval=0 and using the nvidia inspector to force vsync on, triple buffering and frame rate limiter to 58 fps. I didn't notice any input lag while steering character maybe a little with menus such as the pipboy.
I recommend making sure that all the 3 fallout 4 ini files are read only after you alter them since fallout4launcher.exe will reset some settings such as the "ipresentinterval" parameter.

Hope this helps!

Same for me it is like horrible lag spike with 60fps solid. Playing arruond with all kind of driver options for vsync and frame limiters only reduces it buts its still unplayable :(

Post your specs guys who have the same problem here. I am having win7 ultimate WITHOUT SP1 so tell me, do you have installed sp1 on win7 ?

The only thing that somwhat improved it (but its still horrible) was limiting frame rate in the inspector to 58 like mentioned above, then ensuring the game is on fullscreen mode. May just have to wait for an awesome person to mod this like the other fallout games. If you figure anything out please let me know.

Guys you have got to ditch the ingame vsync. It's abysmal! Change the 'ipresentinterval' ini but do not allow the frames to be uncapped above 60fps. Use NVCP vsync, triple buff and Rivatuner 60fps cap and I think you'll be happy with the results.

Tried msi after burner nvidia inspector limited the frames and disabled ingame vsync ... nothing helped ... the video says it all ... no fixing for me for now

I'm sorry for my ignorance, I would really love to try this but i'm not sure how. Could you please explain a bit more.

Found it, trying this now.

This worked!

The link above also includes some mouse movement fixes, but if your just wanting to fix the stutter here it is.


Ok so as you may know the V-Sync in many games is splendid for eliminating screen tearing but often introduces input lag/mouse lag in game which is probably my #1 pet peeve in all gaming, especially FPS games.

In Fallout 4 (and any other Bethesda game on the Creation Engine) V-Sync is forced on with no option to disable it without editing the config files. Problem is the physics engine is tied to your FPS so disabling V-Sync thus increasing FPS over the set limit can cause allsorts of undesirable consequences. In Skyrim it caused serious issues (dat bumpy cart ride) and in Fallout 4 it seems to mess up lockpicking, accessing terminals and other things.

By default Fallout 4's V-Sync limits your FPS to half of your monitors refresh rate. For example i have a 144hz monitor so with V-Sync on i'm limited to 72fps max at all times.

So we want V-Sync disabled for better input "feel" (and trust me after doing this it's worlds better) but we don't want to mess up the physics by letting the framerate get too high. Onto the guide for getting your mouse movement as accurate as possible.

Disable V-Sync

1) Go to your fallout4 folder in documents, mine is located in "C:\Users\Ash\Documents\My Games\Fallout4\"

2) Open Fallout4Prefs.ini with your preferred text editor.

3) Find the line iPresentInterval=1 and simply change the 1 to a 0.

4) Save the .ini and close the file.

Limit the framerate

Make sure you've got Afterburner & RivaTuner both fully up to date after installing or the FPS limiter might not work

1) Download and install MSI Afterburner. Then launch it.

2) Open RivaTuner, located in your taskbar.

3) Add Fallout 4. Find where it's installed on your PC, for me it's "D:\SteamLibrary\SteamApps\common\Fallout 4\fallout4.exe"

4) Use the framerate limit option to limit your FPS. I've set mine to 72 as i don't seem to have any odd physics issues with it capped at that but you could try 60, maybe even 100+. Not too sure what the game has to hit before it has problems. EDIT: Make sure your "Application detection level" is set to medium or higher or it may not work! Thanks to /u/seeberger48 for noticing this.




In his guide he says he set his framerate to 72. I used 58 and I get no more stutter, not sure if it matters, I think the point is to apply a limit of any kind, as disabling the in game vsync through the ini file removes the framerate limit.

Well tried that method with the nvidia inspector and didn't worked. Will try this with 30fps lock and then will do as instructions above with riva tuner and msi afterburner and will post the results.

Did you update your vid card drivers to latest version? Did you pick the Fallout 4 profile for editing in nvidia inspector? Also always install service packs for windows folks!

[Mean Machine]

It is not from the drivers, I can place newest because since version 537 or something they crash the windows desktop manager because I do not have service pack 1 for my win7. Maybe that is the reason I have the same stuttering here as the only other game I have it the same is Dying Light. I guess I need to reinstall new windows7 with Service Pack 1

[Mean Machine]

by the way later after work i will limit the fps to 30 .. to see if there is gonna be any stuttering like in the video i posted earlier

Another (weird) fix: the stutter disappears if you enable the FPS counter in the Steam in-game overlay.

Well i had the stutter with steam fps counter on :)

You don't have to reinstall windows 7 in order to install service pack 1. Run windows update, it should offer you the service pack 1 installation and if that doesn't work go to https://www.microsoft.com/en-us/download/details.aspx?id=5842 and download windows 7 service pack installer from there and run it.

Thanks for the link, I couldn't find it ... will do. Now i am trying to install them but having some issue.
