How To Instantly Improve Unreal Engine 5 Performance!

In this short video I go over a simple trick that can help you instantly improve your Unreal Engine performance and solve minor engine bugs. This is one of the most used tricks in Unreal Engine game development, and I personally do it all the time!

List of Files/ Folders that are safe to delete:
.vs/ .vscode (C++ Projects Only)
Binaries (C++ Projects Only, will require a rebuild if deleted)
DerivedDataCache
Intermediate
Saved (Move any needed logs and screenshots out first)
.ignore (make sure it's not the gitignore or p4ignore file)
.sln file/ code workspace file (or any other IDE file you may have)

List of Things that you should NOT delete:
Config (Holds all your settings)
Content (Literally all of your projects content files)
Plugins (If you have extra plugins they go here , plugins have their own intermediate folders)
Source (C++ Projects Only, contains all your source code)
Script
.Uproject file

You can delete those safely, especially when there's something wrong with the editor, however, when doing it for regular maintenance or to save disk space (which a lot of users do), I would recommend to keep Intermediate/Config and Saved/Config as those contain changes made to Editor Preferences and Plugin settings that might be worth keeping.

Same goes for Autosaves.

Amazing! I just tested it in UE 5.3.2 (including what @Cpt.Tripps mentioned) and it worked great. Thanks!

Thanks a lot! It really boosted my project's performance! :)

Just remember, while doing this just save a backup in case something goes wrong.

Thanks! I cannot open many UA5 projects that had Sequencer. It says "This project requieres the "takes" plugin, which could not be found" ... would this procedure from your video solve my problems?

Bookmarking this one for sure! I'd *love* to find a list of junk I could safely pull out of the engine source files (stuff like support for MacOS or VR in projects where I'm not targeting those platforms, for example) that aren't secretly a dependency for something else that's going to break.

Config can be deleted too. Sometimes it is all about config due to you did something strange with project settings. Although brute, but effective metod. If some wierd shiet is going on with unreal it really might help.

So I have been having an issue where my menus just cause stuttering. I tried this and even after relaunching and clearing out duplicate files and temporary files it still has the stutter. Any Suggestions?

Thanks for this, good to know about these niche solutions from inside a development team
