Unreal 5.2 FPS dropping after a few seconds

I am facing a pixel streaming issue in Unreal 5.2. I am using the metahuman application for the talking system. While we use the application as a standalone in my local machine or open a standalone application inside the AWS (Windows) instance, it’s working with constant FPS.

When I start running as a streaming app in AWS through the browser after 6 - 7 mins, gradually the FPS drops to 7 - 10 FPS.

Also, when we tried with 3rd party pixel streaming system, we are not getting this issue. Am thinking some deployment issue while we running as pixel streaming in our AWS instance.

AWS spec:

  • g5.4xlarge
  • Vcpu - 16
  • Memory 64
  • Nvidia a10g 24gb
  • OS Windows server 2022

Also updated the NVidea driver upto date

Notes:

  1. We are using Dx11

I have the same problem.
When I compile Unreal Engine 5.2 Source Code, and create an blank project, after Package, the application FPS is droping, 120–>110–>100–>…–>7。I use stat FPS.

Hi there!

Those specs should be more than enough for most Pixel Streaming deployments, so it isn’t a hardware issue.

We are aware of a performance issue in DX11 on 5.2, would you be able to run DX12 and see if your performance is improved?
