Stuck at 60 FPS with smooth rate disabled

Development Getting Started & Setup

Greetings All,
My FPS is obviously capping at 60 FPS in the editor. Hopefully, someone can shed some light on why.

Some info:

  • (on GPU settings) V-sync is turned off on the Nvidia 980 M, and preferred processing is using the good card, not the onboard crap one.
  • Smooth rate is disabled in editor settings.
  • This is not a performance issue, it is clearly capping.
  • Using a compiled from source version 4.16. However, pretty sure this has always happened.

Thanks ahead of time for any input.

Can you at least force it by “t.MaxFPS 120” in the Output Log?

I have exactly the same problem.

If I type t.maxfps 120 it jumps up to a 120 but if i type t.maxfps 0 to unlock it, it goes back down to 60.

I had the same issue. Don’t know why it was capped all of a sudden to 60 fps but t.maxFPS 120 did the job.
There is some voodoo/bug involved (like switching back and forth frame rate settings in the Project Setting) but it does the trick. At least in my case (UE 4.16.2 running on ASUS ROG GTX 1060).
BTW, same project on a different computer didn’t have this problem at all…

Hi,

I had the same problem (FPS capped to 62 with t.MaxFPS 0).

I solved going to Edit → ProjectSettings → Engine tab → GeneralSettings → Framerate tab → Smoothed Frame Rate Range → Modify Max value.

You can also edit the DefaultEngine.ini file, under [/Script/Engine.Engine].

Hope this could help,

I had this problem before. Project settings didn’t work at all. Max FPS was locked at 60FPS, and delay always 18+ ms.
You will find not only Unreal Engine but also some games have this problem.

Solution: It’s cause by NVIDIA Experience settings. To solve this problem just need to uncheck NVIDIA Experience->settings->games->Battery Boost. After that go to Unreal Engine project settings->engine->general settings->framerate and check smooth frame rate. Now you can set max FPS at any rate and the time delay go back to normal at about 8ms.

Hardware:
laptop(MSI, Only one video card could be used at the same time)
CPU:i7-7700HQ
RAM:DDR4 2400MHz 8G*2
Harddrive:SSD+HDD
GPU:GTX 1060 6G
Software:
windows 10 16299.192
Unreal Engine Version: 4.18

EDIT:
Unfortunately, I found that I have to Uncheck and then Check “smooth frame rate” every time I reopen Unreal editor, or it will still focus on 60FPS and over 18ms. Hope someone could find a perfect solution.

This solution worked for me. MSI Laptop with a GTX1070 and NVidia Experience. None of the engine settings will work if battery boost is turned on. Also for additional information, you will need to restart any running apps to see the frame rate change in those apps - it doesn’t uncap immediately when boost is turned off.

I had the same problem. Project settings didn’t work at all. Max FPS was locked at 60FPS even though I had t.MaxFPS 999

The solution for me was to change the Performance Profile of my Laptop. I have Asus ROG STRIX Laptop so I am able to control the Performance Profiles through ARMOURY CRATE. On other laptops, this can be done directly through Windows Settings’ Power Plans located in:
Control Panel\Hardware and Sound\Power Options

Hi, did you find any fix for this problem I think I actually found the permanent fix after some digging, I know it’s been so many years but if you also found out any fix just let me know im a geek xd -

Step 1 - Open “Unreal Engine” Folder the main installation one
Step 2 - Select Unreal Engine Version for example " UE_5.2 "
step 3 - Open “Engine” Folder
step 4 - Open “Config” Folder
step 5 - Open “BaseEngine” File in Notepad
Step 6 - Hit “Ctrl + F” and search for " [/Script/UnrealEd.EditorEngine] "
Step 7 - Under that section in the “10th” line there will be " bSmoothFrameRate=false"
step 8 - Change it to " bSmoothFrameRate=True " and save and exit

the magic is done its default now I was so frustrated for because of this problem I formatted my pc 3 times today thinking something is wrong with my windows or drivers

I’m so proud of this fix sometime I think I’m mentally ill I just can’t bear with these sudden changes to the default

but any ways if you’re seeing this don’t forget to mark your attendance lmao fr I still can’t belive no dev helped me when i raised the similar quirey

its because of the graphics software
For amd open the adrenalin /Pro software and adjust the unreal engine settings from Perfomance to Quality That worked for me
For Nvidia IDK HAHAHA

My solution involved those steps
plus:
in Nvidia Control Panel
making sure that Nvidia
in general
or if is some specific settings for an app like Unreal
max frames is off
and
vsync is off

Also battery boost in Nvidia Geforce deactivated.

My problems started after I try to use Unreal while on a flight and battery finished. Now everything is fine.
