Ultrawide Performance Issues?

[ThrustFatty]

Got the urge to replay all Bethesda games I own recently due to the realization that I've never done a full playthrough of FNV, and I can't seem to get my performance optimized. Im playing on a 21:9 ultrawide at 3440x1440p, and realized that Fallout 4 (and new vegas) aren't optimized for ultrawide resolutions, but I cant seem to get them to perform well. I downloaded a mod for Fallout 4 to scale the game properly to ultrawide and changed my resolution in the game files but it runs at like 30-40fps with dips constantly. I have an i5 12600k and an RX6800 with 32gb of ddr4 3600mhz ram, so may specs arent the issue. This game on max settings utilizes less than 45% of my gpu, like 30% of my CPU, and barely 10gb of ram, but it still runs very poorly. I know new vegas had a memory patch to make it utilize 4gb of ram rather than 2, which put it at around 60fps stable with dips to mid 40s when lots of ♥♥♥♥ was happening at once, but that was playable. Just wondering if anyone might have a similar issue or a potential fix. THANKS

I found your problem "interesting" because I also want to up-grade to ultra-wide ...

As such I googled "fallout 4 ultrawide" (no pun intended)
thus:

"Fallout 4 does not support 21:9 resolutions. However, as long as it is set to output to a standard 16:9 resolution (such as 1920x1080), the game is still playable on these displays."

And some libraries for F4SE from Nexus.

My pleasure mate!

I just ctrl-alt-del from No Man's Sky because I remembered :

After you start Fallout 4; while in the menu (or any time really) , minimize the game to desktop and use task manager.
ctrl-alt-del is doing just that.

Now, in task manager, right click on Fallout 4 exe:
- go to "details"
then right click again on Fallout4.exe and:
- set priority: "above normal"
- set affinity: un-check cpu 0
exit task manager, continue game !

Those two options should help even more.
for instance "set priority: above normal" !s activated by default in No Man's Sky.

The game engine tries to cap your frame rate to 60 fps. If your display has a high refresh rate, it tries to divide the refresh rate by a number to get it under 60. So, sometimes it overcompensates and caps you pretty low. You can use the High FPS Physics Fix[www.nexusmods.com] to override this. Another option is to disable the frame rate cap in your .ini and cap the frame rate at 60 fps in your drivers.

I figured it out! i verified the integrity of my game files just to find out that the Launcher of the game wasn't detecting my GPU even though the actual game was, and just took a little bit of file tweaking to run as planned.

The Fix for those of you who need it:

This can be determined by going to "This PC > Documents > My Games > Fallout 4 > Fallout4Prefs" and if it says your GPU name under the "sD3DDevice" location, that means the game is detecting your hardware (for instance, mine said "sD3DDevice="AMD Radeon RX 6800"" which is the GPU i have)

How To Fix:
Open the fallout 4 launcher and set you settings the way you want them to be when you play, i just popped on the Ultra Preset.
Go to your "This PC > Documents > My Games > Fallout 4" and then open the "Fallout4Prefs" ini file, and set the following values to what i have pasted
bTopMostWindow=0
bMaximizeWindow=0
bBorderless=0
bFull Screen=1
iSize H=1440 (Or whatever resolution height you want to run)
iSize W=3440 (Or whatever resolution width you want to run)

Then, go to Fallout 4 in the steam library menu, right click on it, go to "Properties", and then "Browse Local Files", and open the Fallout4Prefs file in this file location and input the same listed values above.
Then save both changes, launch the game, and enjoy :D

Changing the prefs worked for me, looking great in 3440x1440 now, thanks ThrustFatty :)

Due to your response I remembered the Solve-90%-of-Crashes for Fallout 4 (Skyrim too)
DISABLE all auto-saves !
ALL of them !
Then save periodically and use "quicksave" as much as possible !



edit: not the topic but hope it helps ...
