Frame rate locked at 30?

[YourNewBFF]

Last time I played it was working fine 80fps or more on ultra now it seems like it's locked at 30fps. I have no issues with other games I play they work just fine. What could be causing this and how do I fix it. Any advice would be appreciated.

It sounds like a vsync issue. The game is designed to run at 60fps so being locked at 30 would indicate that your video card is set for half refresh rate. vsync can be adjusted via your video card's software.

If it is an nvidia card I'd recommend you download their GeForce Experience software and let it optimize your game settings. This will create a profile for the game that should give you a workable set of settings that you can then tweak if you have need. And starting from a known set of settings has the added benefit of allowing you to quickly revert to a known set of good settings should your tweaking result in undesirable side effects.

Edit: But go ahead and list your system specs (Steam | Help | System Information) because you may have an issue with the resolution at which you are trying to run the game or some other issue that the specs may identify.

my guess would be you probably have adaptive half refresh rate set for fallout 4 in the nvidia control panel or you might of accidently set your monitors refresh rate to 30hz or possibly its capped by a third party program. what i would do is reinstall your GPU driver reinstall the game aswell and delete your ini files in my documents.

Is that on a laptop? or on a resolution other than 1920 x 1080?

nope.

Do you know why you cannot run the game in full screen mode? I've only seen this issue reported on laptops where they are limited to 720 lines

because nvidias settings are for some reason constanly overridden no matter how i set them up.
why they are being overidden i dont know but i have a feeling its the ENB

I resolved it by changing my v-sync settings in the control panel, that said when I turn v-sync off I am seeing screen tearing at 72 fps. I thought the only way you would notice screen tearing was if the fps were higher than the refresh rate of the monitor, I have a 144hz asus monitor so I don't know what to think. I never had screen tearing before at 72 fps. People were asking and just in case it's relevant I have a i7-6700k cpu an msi gtx 970 16GB of ddr4 ram and a SSD. I can put it on adaptive and I get consistent 60fps with out screen tearing but I never had to do this in the past to prevent screen tearing. Again any help or advice would be appreciated.

you need to go into your display settings and change the refresh rate on your monitor.

Just a thought but have you created a specific profile for FO4? I've had to do this for a couple of games. This feature is under 3d settings and should load the custom settings you specify when you launch the game. Launching the game thru F4SE may interfere with the loading of the custom profile and you may need to create the same profile for that executable.

Thanks for posting this, friend. Years later I ran into this problem and this was the solution.

Thank you so much

Loading is tied to your FPS. Now unlike Skyrim original, you do not need to cripple the game and your system by running 60fps.
1) Set your monitor bet. 100-144hz, turn on Freesync/G-Sync if you have it, on the monitor itself.
2) Disable v-sync in game and in drivers Enable Enhanced Sync (AMD) / Fast Sync (nVidia) instead.
3) Cap FPS to the number you set in (1).

Any idea how to fix this for AMD processors and GPUs?

I had to change "iPresentInterval=0" within file "Fallout4_Default.ini" (Steam\steamapps\common\Fallout4) and not "Fallout4Prefs.ini" like mentioned in some other threads.

Using window mode I was not able to use a resoultion higher than 1920x1080. But with the mentioned change there was no need to use window mode anymore.
