How to optimize a level after it has been built fully?


I am a beginner to UE4. I have designed a level using the Kites package provided by UE4. When i was developing the level my system used to freeze a lot and at times UE4 used to crash. So i reduced the engine’s scalability setting to low in order to work flawlessly. Now when the level was complete i packaged it and shared it with my friend but the level stills lags a lot and is unplayable. I am quite sure that my laptop meets the minimum system requirement of UE4 but still just to confirm the same i am posting my system’s specifications below:

Model: HP-14 al176tx

Graphics Memory: 2 GB

Clockspeed: 2.5 Ghz

Graphic Processor: NVIDIA GeForce 940MX

Processor: Intel Core i5-7200U (7th Gen)

Ram Type: DDR4

Ram Speed: 2133 Mhz

Capacity: 8 GB

Hdd Speedrpm: 5400 RPM

Hdd Capacity: 1 TB

Hdd Type: SATA

Any help regarding the optimization of level would be of great help. Right now the moment level starts the system starts lagging a lot so i am guessing it’s something related with optimizing the level and stuffs and not my system’s specs. Also i would like to know if there is a way to delete all the unused polygons(like the polygons that gets burried below terrain when i place them below the terrain level or anything just to get a playable fps).

thank you

Kites assets are not meant to be in a game, as you found, it lags a lot! (Check the size of the materials, those are huge!) So consider to replace the level assets with something less expensive :slight_smile:

yeah I figured that out. The textures themselves are 16k maps for some materials. Thanks for your support.
