How to fix FPS stutter issue in UE5.1?

Hello,
I’m working on a project in UE5.1 that I started a few months ago. A day ago, I started encountering weird FPS drops whenever I ran the game in the editor and the packaged version. For the first ten seconds of loading the game, the FPS is high and everywhere seems to be working okay. After ten seconds, the game’s FPS starts to lower rapidly (usually from 60 to 10 in a matter of seconds) and the game starts to stutter to the point where it’s unplayable. It’s not a random area in the map, as standing still can still cause the FPS drops. This issue also happens in the main menu. I’m unsure how to fix this, as I’ve tried changing the rendering and quality settings.

Here are my PC specs just in case:

  • GTX 1660 Super
  • i5-10400F
  • 16 gigs of ram
  • 100GB of space left

Sounds like a programming problem.

You’re building up a lot of X ( something ), and it’s slowing down the system.

It’s probably something you’re creating, spawning etc. Take a look at the code, maybe.

It’s also worth keeping an eye on the outliner. Does the number of actors just keep going up?

Thanks for the reply.

I was able to find a folder which contained a bunch of animated materials. After I deleted them, the game started running smoothly again.
