Really weird issue that I can't seem to find replicated anywhere else on the internet. Basically, my game will launch in one of two states: Choppy with high FPS, and butter-smooth with high FPS.

More specifically, I'll load a save, and regardless of where I am (I have a 3070), if my game has done a 'choppy' launch, my frames when turning the camera will be rough and despite my high FPS, this will not change. If my game has done a 'butter-smooth' launch, my FPS will be the same as always, but there's no subtle choppiness when turning the camera.


Perhaps the most frustrating part of this problem is that the parameters for either of these launches occurring is beyond me, with butter-smooth FPS achieved at random, and the same for choppy.

I have NVTF and OneTweak, the ini's for which I have played with extensively to no avail.

I'm using reshade, not ENB.

I have VSync disabled in my ini's, and seemingly enabling and disabling iFPSClamp does nothing.

MO2 is installed on the same drive as my game.

I've tried disabling all of my mods individually to no avail.

This bout of choppiness seems to occur entirely spontaneously, and I have no idea how to stop it.

Sometimes I'll have about 4 launches in a row that yield smooth gameplay, and sometimes I won't be able to get a smooth launch for the whole day.


My load order is pretty extensive, but I have the Mod Limit Fix and no other noticeable problems in my save. It is as follows.

Any help here is greatly appreciated. I'm at my wits end with this!

Do you get the stutter without all these plugins active as well (Vanilla game + fixes like NVTF)? Knowing this will help narrow down the possibilities.

Having the mod limit fix is something that only removes the hard engine limit on mods, it does not fix any possible performance issues caused by certain combinations of mods.

Does this happen on a fresh save too?

Does Reshade use any kind of frame limiter? If so, have you tried disabling it and using the game's vsync instead?

Lastly, for the sake of troubleshooting, could you share the rest of your PC specs?

I specifically tried this on a fresh save a week or so ago (downloading a fresh save, and starting my own new game), the issue persists there.

I'll have to check that reshade frame limiter thing when I get home, sounds like something that could exist.

This is my CPU: Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz 3.70 GHz
I have 16GB of ram installed.
A 64-bit operating system, running windows 10.
As previously mentioned, a NVIDIA GEFORCE RTX 3070

Not sure if I've missed anything, please let me know if I have.

I appreciate your prompt response and any future help. Thanks!

Try deleting Fallout.ini and FalloutPrefs.ini in ...\Documents\my games\FalloutNV

Sometimes the .ini files can create problems.

Unfortunately that hasn't worked. Thanks for the suggestion though (it has alleviated other errors of mine in past!). I'll keep looking and update if I find a fix.

Were you playing anything before starting up Fallout New Vegas?

Maybe another game is giving you a memory leak. I had that problem with Killing Floor 2 for a long time.

I had considered this last week, and closed everything I wasn't using except New Vegas before launching it, to no avail.

In fact, I once tried the opposite; launching whilst CS:GO was already open, which, much to my surprise, bore smooth FPS (not reliably however).

Thanks again for your contribution.

EDIT: In the absolute miracle that someone else stumbles across this, after so many weeks of troubleshooting, I am now able to enjoy a stable, stutterless game! The fix was simple: Unplug your second monitor before launching the game. I thought I would have to do a full reinstall to get rid of this problem for a while there. Damn this was frustrating. Hopefully this helps someone.
