Blueprints right click menu slow to load

Hello! I’m having an engine problem. Just on my desktop PC, on every project, even empty ones, when I right click inside a bluprint, in the event graph, it takes 3-5 seconds to open up the commands menu. It really really makes it hard to develop anything.
I tried uninstalling the engine and reinstalling. It really isn’t a hardware problem (Ryzen 2600, nvdidia 2060) because in the past, the menu was working just fine.

I’m bumping this so some wonderful person might see it and help me?

It sounds like the issue may be related to your project settings or configuration. Here are some troubleshooting steps you can try:

  • Verify the engine version: Make sure you are using the latest version of Unreal Engine and that it is compatible with your system. You can also try switching to a different engine version to see if that resolves the issue.
  • Check your project settings: Go to the project settings and see if any settings are causing the delay. For example, some plugins or custom settings may be slowing down the event graph menu. You can try disabling plugins or resetting the project settings to default to see if that helps.
  • Clear your cache: Clear the engine cache and rebuild the project to see if that helps. To do this, go to the “Engine” folder and delete the “DerivedDataCache” folder. Then, rebuild the project by selecting “Build” from the main menu.
  • Update your graphics driver: Make sure your graphics driver is up to date, as outdated drivers can cause issues with Unreal Engine. You can download the latest driver from the Nvidia website.
  • Reset your editor preferences: If none of the above steps help, you can try resetting your editor preferences to their default settings. To do this, go to “Edit” > “Editor Preferences” and select “Reset to Defaults.”

Let me start by thanking you for helping me troubleshoot my problem!

This is not a project specific problem though. This happens to all projects, including fresh empty ones.

I tried your steps.

Engine version is 5.1.1, I did a fresh install twice.
I don’t use any custom setting, or added plugins. Just what the engine has enabled by default. (Trying to disable those, causes my engine to crash)
Tried clearing the cache and rebuilding. Nothing happened.
Graphics drivers are up to date.
And I reset my editor preferences to default.

Nothing worked.

I have the same issue now. I recall I had a problem that the right click window was disappearing quickly after showing up. There was a potential nvidia solution to install 1 or 2 reg-files to fix the issue. This may be related again to nvidia drivers or the gpu stuff in general but every possible fix that is related to this right click window lag was not really working for me.
I tested 5.2 and 5.1, both on my own projects as well as newly created templates, they all have the lag. I run all the newst drivers and fully updated win10 version.
4.27 does not have these lagging issues. It started with 5.0 and seems like it got gradually worse with every new update.
Hopefully this gets resolve somewhat soon. Cheers.

Have you found a solution? I’m having a similar issue.

The problem is ongoing in 5.2, and seems to have gotten worse. It is seriously disturbing development now, we need immediate attention on this. I am trying my hardest to learn UE5, but this specific problem is an incredible hit to work speed.

My setup isn’t weak either, I’ve got:

  • Ryzen 5 5600-X CPU
  • 3060Ti GPU
  • 32GB 15CL RAM (should make it nigh IMPOSSIBLE for such a lag to occur)

Any other right click menu opens instantly, but when I click on the empty event graph, there is a highly noticable 2-3 second delay on opening that menu. It’s unbearable, we need a solution fast. I hope someone with authority can finally have a look at this.

Bumping once again. I even did a clean install of windows. Can we get some staff support? This is ridiculous.

If it helps at all troubleshoot my problem, when this happens, the engine counts it as a “Stall”

I ended up docking the blueprint pallet on my screen, just to have fast access to nodes, but this is not a solution. Can someone please help?

Some additional information I discovered while playing around with the pallet : When adding a “Custom Event” from the pallet into a BTTS (behavior tree task) the engine Stalls again. When adding a custom event into a normal blueprint (again from the pallet) it doesn’t Stall.

I have the same issues, tried deleting caches, different gpu driver versions and different projects in different engine versions, the problem persists

I’ve been having this problem too - there’s a second or two pause when opening the right-click menu (even in a blank graph) and also a pause opening a blueprint even if it’s newly created in a brand new project.

And some of my specs are similar to an earlier poster - namely, I’ve got a 3060Ti and a Ryzen CPU (9500x) - could it be something related to these? I didn’t always have the issues and I think it may have started roughly after I upgraded my system.

Also, has anyone noticed this happen on 5.3 yet? I’m not holding out much hope as I’ve had the problem on fresh installs of 5.1 and 5.2 - but you never know!

Make sure Context Sensitive is ON, i am not sure if this is going to fix your issue, but having this off makes right clicking on the graph take longer.

Thanks - but unfortunately checking/unchecking didn’t affect it.

It seems like some sort of conflict - as DCorvinos said, like the engine stalls rather than just taking some time to load.

@DCorvinos have you reported the issue to Epic?

I have the same problem under Linux with UE 5.2. It seems that the number of elements in the list is somewhat proportional to the time the menu needs to open.
That might be an explanation why turning on “Context sensitive” makes it a little bit faster.
In Animation Blueprint state machines there are only very few entries and opening that menu is a lot faster.

Same issue here running Unreal Engine 5.1 on Ubuntu 23.10 with a ryzen 7 and 32 GB RAM

I’m having this exact same problem and have yet to find a solution. Ryzen 7 2700X, 32GB 3000Mhz RAM and Nvidia 3060, large project that takes 13-15 seconds to load this menu. Previously in UE4 it was instant.

Same issue here. Right-clicking in the event graph takes about 6 seconds to show up, causes entire program to hang in the meantime (rest of UI becomes unresponsive) which indicates to me that the lookup code is running on the UI thread. Unreal 5.2.1, Win 10, AMD Ryzen 9 5900X, NVIDIA RTX 2070 Super, 24 GB RAM (13 GB free).

First time using Unreal so don’t have anything to compare to except for YouTube vids.

The freezing behavior happens anytime the menu is being shown, so it also hangs for ~6 seconds when just trying to i.e. “promote to variable” after dragging off a pin.

I just installed 5.3.2 and loaded my 5.2.1 project and the “Executable Actions” context menu lag seems to be gone.

— Edit —

Nope, never mind… Issue is still there with 5.3.2… Here is a screen capture of what is going on in a basic tutorial blueprint:
