Hello, my unreal has been lagging ridiculously for about 3 months, never had a problem with it before until now. My first conclusion was it being due to a nvidia driver update, ive been in touch with them and they have managed to solve a lot of the problems. However it still crashes every 2-3 minutes, and when I try simulate the game its experiencing lots of lag too.
My specs are not the issue, its a relatively new computer with way over the recommended specs, and I have being trying to solve this for ages now, its really grinding my nerves I am completely clueless.
OK lets try to run through some things:
first some possible symtoms that cause lag:
game tick
draw call (includes lod changing, item spawning)
and more (alot more)
How are your world settings - (one way is to) editor → toolbar(the thing you use to build)-> settings->engine scalability settings->(what is there?)
now if you change scalability settings then you might have to restart the editor (has i have done before)
back to game tick, what’s running
BPs
c++ tick
particals
again more
now I run on both an weak laptop and hefty desktop (both extremes) and don’t have many issues with the editor.
I would scan through your project and engine settings, check out the plugins and search for things related to rendering and learn about them.
