As the title says, every time I connect two nodes, the editor freezes for about 2 seconds. This is extremely annoying since it slows down the entirety of my productivity.
Not only this happens when connecting two nodes, but also when I drag out from a node and then right-click (opens the node list and then close it) and when I click on a node input/output without dragging.
This didn’t happen a month ago; I took a break from Unreal and when I came back yesterday, this was happening.
This happens in small and large blueprints and in both large and small maps loaded.
I am using Unreal 5.1.1.
Does anybody have any suggestions on how to fix this?
The only two things I’ve ever seen slowing blueprints down are
-
Complex construction script, while there are many instances of the blueprint in an open level.
-
Capping the editor frame rate with t.maxfps will also cause the blueprint editor to run slowly.
Having said that, if you think something like this
is a normal blueprint, then there could well be a third… 
As I said, I am in an empty level, and a new blueprint, meaning that it is empty.
I also tried using t.maxFPS but still nothing happens. It also turns out that the lag spikes also occur when using the console. When I type t.maxFPS it is fine, but as soon as I add a new character, it freezes.
The freezes however stop for subsequent characters. The freeze here happens when I insert a character that will result in zero auto-fill suggestions.
You can cap the editor frame rate with t.maxfps 20, for example.
To set it back you would use t.maxfps 120.
I’m not sure why you have a lag, then…
I will try to reinstall UE… That is my only hope rn.
After the reinstall, is there a way to completely reset all editor preferences, so that I can verify that it is not the reason for the lag?
I think that’s the default?
Reinstalled it. Still lags. But it is specific to that one project. I tried it on another and the issue is not present.
However, resetting editor preferences solved it for now.
