I moved to UE5.2 a while ago, and have had nothing but problems with it. Even after updates no much got better. I’ve dealt with it for a while, but I’m getting frustrated with it at this point and would like to know if there’s a fix, or if I’m going to have to update to 5.3.
I open my project: lag. I open a blueprint: lag. I add a model: takes 25 minutes. I close a blueprint: lag. I rename an newly added asset: frozen for 10-15 minutes. I open MUE: literally 1 frame per 3 seconds.
I don’t get this with any of my other projects from 5.1, 4.27, 4.25, or 4.21. My coworker doesn’t have these problems either and he’s operating on a PC with worse specs than mine and it’s the same project on the same MUE server. My task manager is below 50% across the board. How is this laggier than Star Citizen and how can I fix this?
My PC: RTX 3070, Ryzen 7 5800X, 64 Gb of ram, installed on a 2 TB M.2 SSD
Have you tried going into your AMD Adrenaline program and setting it to specifically use your external graphics?
For some reason, it’s a problem I hear commonly, and it even has happened to me, where a Windows Update will tell the computer to use the onboard chipset for graphics instead of the better hardware. You should check and make sure you specify what graphics system for it to use.
But wouldn’t that affect all my game projects and when I play video games? UE5.2 is the only one having issues. Unless in that adrenaline program you can set it to use your CPU vs GPU for each independent app
OOP Sorry I just saw the Ryzen 7 5800X part and missed the RTX 3070 part. Just use Nvidia Control panel.
And yep! That’s EXACTLY what it does!
You can set specific applications to use specific hardware.
All of that was already set up. Could there be issue with the engine itself? An issue with engine settings saving has been an issue too. None of the stuff I set saves, so the next time I open the project or engine, I have to redo all of my stuff. Like auto saving, MUE name/color, and some other stuff. Could this be correlated with the immense lag?
Have you tried temporarily disconnecting from revision control to see if your settings there have anything to do with it?
I myself have had issues with lag and Helix Perforce if the settings aren’t just so.
Edit: The reason this came to mind is it is possible that the reason it isn’t saving the settings is you may be grabbing the settings file from the repo and overwriting your settings?
I’m connected to the source control for my other project that are implemented in the same server. This only happened after moving to 5.2 and was an issue before using a source control with some of my other test projects. Is there a way to validate file integrity with the engine, because from what I’m gathering from you and my coworker is this a mystery issue of the gods. My guess at this point is my engine has some bugged files and is causing issues.
Okay, after a painful long time of wrapping up my stuff and trying to push and close the server I validated my files. It made it ever so slightly faster. I don’t lag when entering the levels anymore, and renaming objects only takes 30 seconds instead of 10 minutes. It’s not as fast as my friend’s, but I’ve played enough high end games on a dell laptop in my day to find this okay.
Thanks for your help and all the suggestions. May one day some internet traveler with my same issue comes across this thread and finds one of your many solutions helpful for their weird case
And yeah- renaming taking 30 or so seconds with version control hooked in is kind of par for the course. It has to do with the engine making sure all the references are accounted for. Make sure directly after doing so you fix up redirectors!
After validating my engine, it completely stopped working. Tried to push? Crash? Try to join MUE? Crash. Couldn’t find anything wrong with it at all, everything was there and validating the files again did nothing but anger the beast further.
To fix this I deleted the engine and reinstalled it and now it runs buttery smooth without crashing.
Wanted to give an update in case there’s anyone in the future who had the same exact issue as me and needed to find a fix because none of the others online was working. More than likely it’ll be myself again in 4 years.
