Low FPS [35-40] in Unreal Engine 5 & Components running at around 20% in task manager

Hey, I am running:

  • Nvidia GeForce GTX 1080 (8GB)
  • DDR4 Ram 4x32GB
  • Intel Core i9-9900K @ 3.60GHz.
  • An NVME M.2 (Fast hard-drive) which the engine and project is running on.
    All components are 3-4 years of age now.

I am having some issues running Unreal Engine 5 on a stable 60FPS. I know my hardware is getting outdated year by year, but I am surprised at how low it is. I am currently running the Content Examples project with the Animation map where my FPS is around 35-40 FPS and around 24 ms. The game is using Lumen and settings are set to Epic.

Looking at the task manager view my components are at around:

  • GPU at 18-22%
  • CPU at 14-20%
  • RAM at 25-33%

My question is: Is the task manager reliable to view the usage, and why is the engine not using more of the resources available?

When you go to your ViewportOptions, left to “Perspective” and “Lit” and select STAT => ENGINE => DETAILED, what does it show you?

Hey, thank you for trying to help!

Here is a screenshot. The FPS seems a bit more stable today, however there is no change in the number of applications running since the previous screenshot, only that I restarted my computer, which was done for the previous screenshots as well:

Soo what I can see is that your GPU is maybe on the “lower” end for this scene(the red numbers are from tabbing out and back in, I mean the numbers on the left). When you look at my scene I have a few more FPS with this:

Core i7 4770K
24GB Ram
1080 TI

Just looking at the values you can see that GPU is very high for you and also the VRAM. I can later check with my Laptop what it will do with this scene.

Thank you very much for this information! I know my hardware is getting worse and worse by the year, and this gave me some form of relief. I’ll see what I’ll do in terms of GPU! :slight_smile:
