I am using some of the assets from the Open World Demo Collection, and any time that I try to place something, say a static mesh, the engine freezes up for a good minute before I can even do anything else. This has only started with the addition of the new assets, so I suspect that they are just too detailed to work quickly? I’ve changed my quick settings to as low quality as possible to try to fix this, but nothing yet.
Could you give me the specs of your computers hardware? Then i could estimate if this is your limiting point.
This is totally normal for that content.
The open world assets where made for a high end video, on a even higher end computer.
All the textures, meshes, materials are high end, 4k/8k textures, high poly… its not made for regular computers or video games.
So… thats totally normal for that content, which… well… if you googled even a little or asked around you would know 
I’m using an MSI. Intel Core i7-4720HQ
2.69GHz with 12.0GB of RAM.
Thanks for the information, sans your smug criticism of the way I use my online resources. Keep up your work of inspiring new Unreal Engine users
