Horrible performance on a good PC

Development Programming & Scripting
1

Updated from regular Windows 11 to Windows 11 LTSC. Before, everything was fine. After I updated, whenever I open the project, the engine starts lagging so much that the window manager crashes. My setup is RX 6700 XT, Ryzen 5 5600 and 16Gb RAM.

Hi @Flamey_8309 ,

Your specs are solid for Unreal Engine, so the hardware itself shouldn’t be the problem

Here are some possible solutions for the issue you’re having:

  1. Update your GPU drivers (download the latest version).
  2. Switch the project to DirectX 11 in the engine settings.
  3. Disable your antivirus temporarily, as it might interfere with Unreal files.
  4. Verify the installation of Unreal Engine through the Epic Games Launcher.
  5. Run Epic Games Launcher as Administrator.
  6. I also read that Windows 11 LTSC sometimes limits RAM usage, so try increasing the pagefile size to improve stability.

If none of these work, you can share the crash log so we can check the exact error in detail.

Hope it helps!

Okay, thank you. I’ll try increasing the pagefile, since I haven’t touched it, though I always set it to 8GBs.
