I’m starting to think there’s some sort of general GPU memory leak happening with UE 5.5+
I previously had an RTX 4070ti with 12GB of video memory, but I kept getting various errors from the engine telling me that I’ve run out of video memory. After getting it several times between 5.5 and 5.6, I decided to swap out my GPU for an RTX 3090 24gb. Sadly, this hasn’t made a difference as I’m still experiencing regular crashes across multiple projects. This has led me to believe that there might be some sort of memory leak in UE 5.5+, and I’m wondering if anyone else has been experiencing this?
If you’ve had similar issues, please post here. Keep in mind, I’m specifically talking about GPU out of memory or other GPU memory related errors.
Have you tried using the r.textureStreaming poolsize= to increase the memory?
Try Uninstalling your graphics drivers, then do a manual restart, and proceed with a clean install of the latest version of your display drivers, then restart and see if that fixes it.
If that doesn’t work, I would back up your projects and the vault cache (optional) uninstall the launcher, restart, then reinstall the epic games laucher and that should fix it.
Good luck!
