Severe Frame Drops in Packaged Game - Need Assistance

I’m experiencing a severe issue with frame drops in my packaged game, which I developed using Unreal Engine 5.2 with Forward Rendering. The game runs smoothly in the Unreal Editor and even after packaging, it performs well on my setup. However, some users, including myself, have reported significant frame drops that were not present during development.

Development Setup:

  • GPU: NVIDIA GTX 1060

  • UE Version: 5.2

  • Rendering: Forward Rendering

Issue Description:

The packaged game exhibits severe frame drops for certain users, which is showcased in the attached video link. Interestingly, my colleagues and friends with different setups do not experience these performance issues, and the game runs smoothly for them.

Minimum Speculated Requirements:

  • CPU: Intel i3-9100F

  • GPU: AMD RX 570

  • API: DirectX 12

Example User’s Spec Experiencing Issues:

  • CPU: AMD Ryzen 5 5600X

  • GPU: NVIDIA RTX 3070

Additional Information:

Given that the hardware in question exceeds the minimum requirements, I’m unsure what could be causing such drastic performance degradation post-packaging. This issue seems inconsistent and doesn’t affect all users.

Questions:

  1. What are some common issues that could cause such a significant difference in performance between the editor and the packaged game?

  2. Are there specific settings or configurations in the packaging pro

Using complex logic in tick nodes can cause performance problems.

The packaged game will also set the default video settings to “Epic” unless you have implemented graphics options.

I agree, complex tick nodes can be a real pain. They can lead to all sorts of performance issues, especially in larger projects. Breaking them down into smaller, more focused functions is definitely the way to go. And don’t get me started on default Epic settings! Players need options to balance visuals and performance.
