Every first time I launch the editor I get an insanely long load time, like 10-25 minutes.

After that, each next launch is super fast 30-90s.

The parts that take a lot of time are:

- initial splash screen - after the launch it takes about 1-2m till the UE appears on the task bar and shows a splashscreen. It’s present in Task Manager all that time though,
- steps with “loading X modules for X plugin “ - this is where most of the time is spent.

Specs: UE 5.7.0, win11, 64gb ram, intel ultra 7 265, rtx 5070, c++ project. Task manager usages are: disc 2%, CPU 6%, memory 22%.

This happens on first launch of UE after starting the PC.

Happens also when I launch it first time after 6 hours since the PC booted (so seems not to be a ‘cold boot’ issue).

Happens when no files were changed since last launch.

Happens every time I reboot.

It happens only to one user, it’s a freshly setup PC, fresh system installation.

Things that we tried, that did not help:

- Excluding .exe files in the antivirus
- Deleting Binaries / Intermediate / Saved
- Re-downloading whole repo
- Turning on very long file names in regedit
- Changing repo drive
- CrystalDiskInfo reports all drives at 100%, no visible errors or red flags
- full system format
- moved repo to system drive
- set up DDC
- tried with a different user account - same thing happens. However, once one user tries launching it and it take a lot of time, when the first user logs off, another user will have a normal fast start on their first try

What else can we try?

What drive is your DDC on?

Should use a Non-OS drive with plenty of space for DDC.

Yeah, DDC is on a separate drive, plenty of space.

Got it fixed.

What we eventually did was to turn on NTFS Journal on a **separate** drive than the repo is on, that had this option turned off for some reason. After that everything works as fast as it should.
