I need help with my game


My game is an open world game and its using World composition. I broke up the map into tiles and each tiles has 150 - 350 static meshes. When i hit play in editor it takes 4 - 5 Minutes to open the game window an then its still very laggy… when i move around the map and the engine begins to load a new tile the game hangs again 2 - 3 minutes. So i cannot properly test my game. How can i test my game without lagging? I have read that the solution is to package the game before testing. But this takes every time 5 - 6 hours. I dont want wait every time 6 hours before i can test my game. Is there any other way to speed up the load time or to test my game without waiting 5 minutes and laggging?

There must be a way to test large open world maps without cooking everytime the whole project for 5 hours/ waiting 5 minutes to open up the map and then to wait everytime again 5 minutes to load each tile from the map during gameplay testing…

How do handle this other developers that developing open world games with ue4? How they test their games without lagging? I dont think they cook the whole game everytime…

CPU: AMD Ryzen 5 2600
RAM: 16GB DDR4 2400 Mhz
GPU: AMD Radeon RX 580 8 GB GDDR5
HDD: 1 TB + 250GB SSD
OS: Windows 10 Pro 64 bit

Try using level streaming to unload all tiles but the relevant one. That should speed up loading

How many tiles are you using? Maybe you need smaller ones?

Anyways check out the Live Training for landscapes and world comp, a lot of info about performance in there.

Also maybe your meshes are crazy high detail and not using LODs?
