UE5.1 & UE5.2 Adding Blueprint Nodes (RMB Menu) Lag

I’m looking to get a performance issue resolved.
When trying to add any blueprint node in the blueprint editor (using the RMB Context Menu) I will get a delay anywhere between 2 to 3 seconds.
This occurs in all versions of UE5 (with 5.0 maybe showing a slightly less delay). I’ve confirmed UE4.27 has no delay. It also occurs no matter the state of the project files, even a brand new project will have this delay.

Would anyone be able to help or offer insight?

I’ve attached a video example and provided list of steps I’ve tried so far (by working with staff members from my school) to address or locate the issue:

Computer Specs:
CPU: Ryzen 9 5900x
GPU: MSI RTX 3080
RAM: 32gb
Windows: 10 Pro
SSD: Sabrent 2tb M.2 Drive (currently using 312gb dedicated partition for anything UE and currently with 189gb of free space in that partition)
Monitor Setup: 32" (non G-Sync Compatible)

Steps I’ve tried:

  • Verifying the installation files
  • Disabling and uninstalling non-default Plug-ins
  • Uninstalling and Reinstalling the engine
  • Removing the engine, creating a new partition for specifically unreal engine and projects, reinstalling it onto that partition
  • Disabling some of Windows 10 appearance settings
  • Edited the baseengine.ini file to increase its CPU prioritization
  • disabling Lumen
  • confirmed taskbar is always displayed
  • confirmed only in UE5, across any project (even brand new empty ones)
  • Microsoft One Drive isn’t installed
  • confirmed no CPU overclocking
  • tried both Game Ready drivers and Studio drivers, even went back to Game Ready Drivers and did clean install
  • did Registry Update Nvidia files
  • bought cheap corded mouse to ensure it wasn’t mouse-device issue or brand issue (currently use Logitech G600 with Logitech Gaming Software)
  • updated AMD CPU files with Adrenaline Minimal Install package (full package causes Error 182 message).

As of the release of UE5.3, the performance issue is resolved.
