Editor Freezing When Submitting To Perforce

Accidentally deleted last post

I’m currently experimenting with Perforce hosted locally on my machine, just to get familiar with it and to test if it’d be suitable to move my team across to from GitHub. Never used Perforce before today.

I’ve set up a server on my machine, following the Unreal documentation for it, and so far it seems to be working, apart from one issue. Whenever I make a change and attempt to submit the changes using the revision control button in the bottom right of the editor, it submits my changes, but then the submit changes window closes and the editor freezes. The changes have correctly submited to Perforce, I can see them in my history on P4V.

Not sure how to fix this, I have tried clean reinstalling graphics drivers as I found posted here, and I have made sure I’ve got enough spare space on my PC. Not sure what else to do to fix this. Any help would be appreciated.

And I’m running 5.2.1, if that helps

hi,
New Perforce user here. I am having the same experience as well. The ‘’ Submit Content” button will casue the editor to freeze. However, somehow I figured out that it will be fine if I do “Submitt Changelist…” using the View Changes window. This way the editor won’t freeze and will work as normal.

I am so confused at the moment because both Submit Content and Submitt Changelist have slightly different pop up windows. one without validation checked while the other does.

Thanks Mason I’ll try that out.

Also having the same issue though. I’ve set up a perforce server on AWS, and I have two workstations that I access with the same super user I created for myself. I use seperate workspaces on my two seperate workstaions. Unreal to Helix server works fine on master workstation, but it freezes the editor on submit of anything on the other.

Thanks Mason I’ll try your solution, but it would be great to figure out how to submit regularly without freezing the editor

This is a crazy Bug. Nobody really knows what is going on! I’ve just read another Thread with more answers but not a single one worked. This one at least did the trick! (And I’m in 5.3.2 for now). Do you think it has something to do with windows 11? Just checking: I’m the only one in the team with Win 11 and the only one to have this issue…

I was having constant freezes in UE5.3 when using Source Control (especially during Submit). After some digging, I found the cause: running the editor in DirectX12. Switching to DX11 solved it completely.

How to switch to DX11:

  1. Create a shortcut to your UnrealEditor.exe (found in ...\UE_5.3\Engine\Binaries\Win64\).
  2. Right-click the shortcut → Properties.
  3. In the Target field, add:
-d3d11

Example:

"C:\Program Files\Epic Games\UE_5.3\Engine\Binaries\Win64\UnrealEditor.exe" -d3d11
  1. Launch Unreal through this shortcut.

Tip:
To check which DirectX version the editor is currently using, open the console in UE and type:

r.rhi.name

:white_check_mark: After switching to DX11, my Source Control freezes disappeared. Hopefully, this helps others!
