Low FPS without ussage

Hey guys,

I just began with learning UE so i try to get in touch with all the functions etc. But now i run into a problem. Sometimes i just have 15-20 FPS and sometimes my full and normal 120. I tried changing quality settings (i have a few FPS more on higher settings, dont ask me why), my GPU is not barely used and changing settings does!t helps at all.

Did some of you guys have/had the same Problems and can help me?

Thanks alot for your time and have a great day!

Do you use Event on Tick nodes somewhere?
