Even with all the settings and best practices in the documentation applied, the frame rate in my game is still incredibly slow. What can I do to increase the frame rate? (Using HTC Vive)
Hi Mate I will try to answer your question as best I can, I had the same problem I’m making a horror game and my FPS got extremely low to about 20fps, It was due to the fact that it had about 15000 actors in one scene, so what I did is split the game up into levels and added level streaming to the game so when the player enters a box collider it will delete a level and add a new one so there was only 2000-3000 actors being played at any one time this helped increase the FPS rate and make the game run smoother and also helped for developing purposes.
Here is a link to a tutorial in order to do this: level streaming ue4 - Bing video
all you need to do is on a box collider is on collision load level and also add another one saying unload level, this will make your scene feel like its all one big level or scene but in reality it’s a big scene with loads of small levels but still making the player feel like its one big level. Hope that helps
