Discussion Fallout 4 decimal FPS setting mystery

[Majorjim]

Hi all. I love FO4 and have played on PC for years. I’m very sensitive to game stuttering and the like so I have, like many, done a very deep dive into settings to get the game running well. On my old 970GTX the best I got was fullscreen, FPSclamp off, ingame Vsync off, Vsync on in Nvidia settings and FPS capped at 64FPS. This removed 99% of the stuttering. Now I have a RTX2060 and a newer 144hz free sync monitor I have been trying again to get a smooth experience. I’m getting close but I’ve run into a strange issue that is very annoying.. I’m still using fullscreen, clamp off, no ingame Vsync, Vsync on in Nvidia settings and I’m now using the High FPS physics fix which is great! I was fiddling with settings and checking strafe stutter which is pretty much the only stutter I get and it’s very minimal. Now it seems 62FPS comes closest to removing this strafe stutter. I was happy with this for a while but decided to try some decimal FPS settings. And holy hell! 62.5FPS is transformative! It feels like a different game. All strafe stutter gone. This lasted a while but it seems that setting the FPS at 62.5 occasionally causes not FPS related mouse jitter. I don’t understand what’s causing it.. I’ve tried without the FPS mod and it’s the same. I’ve tried Vsync off and a bunch of other settings and 62.5 whilst being by far the smoothest setting it causes that mouse jitter. What’s odd is pausing the game stops the jitter temporarily. Any ideas? Anyone tried a decimal FPS setting in FO4?

Maybe try messing around with changing mouse polling rates.

If you have an older Windows installation it could be the cause of your stuttering. I had a Windows install that was getting really old and I kept getting stuttering in more and more games unitil I finally broke down and reinstalled Windows.

Once I reinstalled Windows, Bingo, all the stuttering from every game that did have stuttering was gone like magic. So if you have an old Windows installation I strongly recommend you give it a try. Yes it's a big pain but it's worth it not to have to spend endless hours troubleshooting stuttering issues.

That doesn't really clarify whether the fix was just doing a reinstall, or updating the build version.

You are correct but it still worked regardless. I put off reinstalling Windows for way too long and after I finally did it, I keep kicking myself for not doing it sooner because it fixed 99% of the problems I was having and it could have saved me many hours of frustration trying to troubleshoot one thing after another.

Edit: I'm not saying it's a magic bullet but there's a good chance it will help things fora lot of people with old OS installations.

In those cases I would recommend to first disable the page file/virtual mem and then re enable it. Maybe throw in a defragmentation in between dis and re enabling.
A fragmented pagefile will introduce a lot more read/writes.

I'm just saying it would be more helpful to both you and others if you'd just simply take note of the OS build version you're on before doing anything as drastic as a complete OS reinstall. That way you could just try doing an update to the new build version if there is one, and perhaps fix the problem a lot easier that way.

That's interesting, I didn't know disabling and re enabling the page file could help. I guessing you mean on HDD's not SSD's. I have an SSD as an OS drive now and I trim all my SSD's often though I do have a couple HDD's too that I use for games (that don't require an SSD) and for storing stuff. I always keep them fragmented but I have my page file set up to work on my OS SSD. You are probably right though, it would help people with old OS installs and an HDD for thier OS drive.

Personally I always keep Windows updated, as well as all my drivers and it really didn't help things in my case though it probably kept my OS install from crapping out on me totally lol

You are right though, many people neglect OS updates and it's a big mistake imo. It will cause even more problems if you don't keep Windows updated, that's for sure.

Even on an ssd, sequential reading is faster than if it's in chunks, the difference is a lot smaller than an mechanical drive but if you are chasing rare stutters it is still something easy to at least try.

Yeah I just wasn't sure if you were.
