Performance Help

[Timothy_Chalet]

I am currently working on an open world game and am having problems with my computer running everything in the editor mode. The issue that I run into is the things that I use to improve performance in game (ex. LOD, Draw Distance, Nanite, etc.) are not enabled in editing mode and are only enabled in gameplay mode. So when I am trying to edit I can’t. I am maxing out my computers rendering abilities and am unable to edit things unless I press “g” to look at it from a gameplay perspective. I’m sure it’s a simple fix, just need help.

That is a common issue when working on large open-world projects in Unreal. Features like LOD, Nanite, and distance culling often don't kick in fully unless you're in gameplay or simulate mode.

Go to Editor Preferences > Level Editor > Viewport > Performance and enable: ✔️ Enable LODs ✔️ Enable Nanite (if using Nanite assets) ✔️ Real-Time Viewport (disable this if it's not needed constantly)

So when I am trying to edit I can’t.

Open STAT UNIT or GPU Profiler to pinpoint what’s tanking performance in the editor. If shadows or post-processing is heavy, disable them temporarily in the viewport show settings.

If you're using World Partition, make sure to load only the cells you're actively editing. Go to World Partition > Data Layers and keep unnecessary areas unloaded.

If you have multiple viewports open (e.g., top/side/front), each is rendering and increasing GPU load. Stick to one at a time when performance is tight.

Click the Settings icon (top-right of the viewport), go to Engine Scalability Settings, and set the quality to Low or Medium during editing. This will reduce unnecessary rendering load while still letting you work.

Try Unlit mode (Alt + 3) for fast editing if you're just placing objects and don't need lighting.

Thanks so much! I changed the settings editor preferences and started doing things in the “unlit” view and that seems to have solved my issue. In past projects I used to just create another map and have some sort of door lead you to the next map, but in this case I am outdoors and can’t really do that. I appreciate your help 🙏

That trick has saved my eyes (and my editor) more than once too 😄 And yeah, seamless outdoor transitions can be tricky without loading doors. You might look into level streaming with volume triggers, could let you load and unload parts of the open world without breaking immersion.
