Fallout 4 PC: How To Fix G Sync, Crashing to Desktop, and Flickering in FO4

4m 9sLänge

Fallout 4 is a great game, but it has a ton of bugs especially on PC. The FO4 game engine doesn't properly run above 60 fps, so if you use Nvidia G Sync with a variable framerate it becomes unstable. G Sync 120 Hz and 144 Hz monitors all cause problems in Fallout 4 without a few setting changes. I show you how to properly adjust the PC game settings when you have G Sync equipment, how to resolve certain crashes to the desktop (ctd) by adjusting your RAM speed / frequency, and how to fix the rapid flashing on launch. With a couple tweaks you should be able to fix Fallout 4 crashes and bugs, eliminating all your problems.

Thank you, you helped me.
From my testing, GSYNC with VSYNC off in the Nvidia CP you will experience screen tearing in any game. But… if you turn it on VSYNC in the Nvidia CP only, the that's when GSYNC will shine the most. Even Nvidia reps have said that turning it on in the Nvidia CP is recommended. So I that's what I did… then I just placed a frame cap using MSI Afterburner and BOOM! Smooth as a butter.
do you know how to stop micro stutter in fo4? i run at consistent frames but i get micro stuttering even though the fps counter is saying60fps any advice would be appreciated.
I cant get it to work on Fallout 3. I disable vsync, iFPSClamp - 60, and GSYNC enabled. I get screen tearing :/ anyone had experience with f3 and gsync?
Same monitor as me!
This is a good method. Different to the one I was using previously (force vsync off in ini, then limit to 60fps using nVidia Inspector) and seems to work better.
Thank you.
Bethesda makes the buggiest and shitty quality games. Every game they bring out Fallout and Skyrim...how are they so successful. They're riddled with problems.
DDR4 crashing due to any program still means it's a problem with your memory setup. The program is just stressing it more than normal or possibly even using part of it other programs don't use.

A "buggy" program can't cause system memory to be unstable. That's just not how computers work. Your memory is either stable enough for all conditions or it is not.

So I suggest you start with XMP or tweak it a different way whilst running Memtest86 etc until you achieve a stable setup.
If g-sync isn't working at all you got to make sure that the in-game v-sync is deactivated.
Steps:

1. Go to "Documents\My Games\Fallout4" open the Fallout4Prefs.ini File with notepad and find and change "iPresentInterval=1" to "iPresentInterval=0"

2. Open Nvidia Control Center go to 3D Settings -> Manage 3D Settings -> Program Settings -> Fallout 4 and change only the "Vertical sync" settings to "Use the 3D application setting".

In my case this allwed g-sync to be activated. Next thing you got do do is limit the games FPS with Nvidia Inspector or Riva Tuner.
Having physics tied to the framerate isn't a flaw, it's conscious design decision. Otherwise every non-static object, which there is a lot in Beth games, has to be able to interpolate every random value of dT thrown at it. Not only do you get better performance but you manage to remove an overwhelming amount of potential edge cases by assuming a fixed timestep between frame calls. It might have worked in a PC-exclusive title, but not for one in which the developer needs to first hit their target framerate for the platform in which they will make the most profit. Otherwise, great video!
I dont have the whole list of Nvidia only I got 3 things
When i lock the fps to 60 i notice the game play is sluggish and i didnt use the control panel i used nvidia inspector http://www.guru3d.com/files-details/nvidia-inspector-download.html if you havent used it before theres this https://www.youtube.com/watch?v=syE55-jEzb8 and fps 75 is to me the sweet spot.
I downloaded nvidia inspector and under sync and refresh I limited the frames to 75 and put vertical sync to force off and the gameplay is flawless your way turns g-sync off
