100% SSD Causing Super Slow Performance & Freezing Fix for UE5.1 Unreal Engine

[tommywright]

Just started having this in 5.4 and either moving the cache files or the Windows search indexing fixed me (I did both at the same reboot). Thank you!!

Assumption is your Virtual Memory / Page File setting is the default "System Managed" and has set itself up on C:\ so when you are using RAM intensive programs like UE editor when it swaps/pages our stuff in RAM to the pagefile its writing to that file and overloading the disk. If you want to monitor what is writing to the disk to confirm / if its not that then in the Task Manager under the Performance TAB select the "Open Resource Manager" link a the bottom then in the Overview TAB make sure "Disk" is expanded and sort the list by Write or Total and you can see the Processes and Files that's causing the disk usage.

I just had this "super slow editor" in 5.0 recently. It never really did that before. I am using SSD's (2 of them, one for engine and vault, the other for projects). Moving them to HDD is a no-go, its way too slow to handle my 100GB projects. I just closed down UE5, made sure the launcher was also closed down, then reloaded my 5 project and it worked like normal. Knock on wood, but hopefully it doesn't happen a lot.

When you change the cache vault location, does Unreal Engine download those files to the newly selected drive?

Hello there sir, I downloaded unreal engine 5 recently &, I'm facing a problem/issue with it, the issue is, I wanned to model a shape in it, I used a function called vortex sculpting to deform the shape, suddenly, unreal engine freezes, & I don't know why is that, I can't figure out the reason, I need help & guidance from you, please, could you help me, I'd appreciate your care & response, thank you

That SSD is also rather slow for todays standards, I think it max's out @600mbs so can easily be saturated just by the OS.
I noticed this happening to me a few years ago so switched over to Samsung 980 pros (gen 4) and they never use over like 20% as they top out @7500mbs
