I have been struggling with editor lag issues for a while with UE5, currently using version 5.1.1.
When I open any blueprint class or the level blueprint, even for an empty level of an empty project, there is a couple of seconds delay. Opening the blueprint context menu with right click or tab takes about 2-3 seconds every time.
This is not happening with the material or Niagara editor, which are working smoothly.
I checked many things: set “Prefer maximum performance” in NVidia control panel app settings, made sure there is no max frame rate set there, disabled full screen optimizations compatibility mode in Windows, made sure that no in-game overlay is running, but nothing helped.
Are you usually the type to play around with things and settings when installing Windows for the first time? Apart from the unnecessary applications and setting up the windows background, as well as the monitor refresh-rate I rarely touch any settings.
Perhaps you have played around and caused some issues that way. I suggest making sure that all drivers are up to date.
Thanks Elias. I try not to play around with settings unless I have to. It is possible that something is off, although it is strange that this only happens with blueprints and not materials, niagara, meshes and anything else. I made sure the motherboard and the gpu drivers are up to date, although this is a long existing issue for me with UE5.
argueably normal. the blueprint is traversed and code resources loaded. on first open this can take a second or 2. subsequent loads are usually faster. (unless you reload it rarely and the loaded data was removed by the editors garbage collector to clean up unused resources.) those are all the common things.
