Ever since 4.8, everything seems to slow down when playing.
I have already posted something like this in the forum, I think?
But I still don't understand it, sorry.
I've never had any problem with 4.7.6. But 4,8.X and 4.9.X and the preview of 4.10 are just not running well. I have no idea why. It only slows down then I play it the level. I can somewhat play it on Low but Medium and up just makes it slow down to a crawl. I am using a laptop. I have tried making it use Nvidia instead of Intel (Integrated). I have tried r.GraphicsAdapter=0 (the same). But it's still slowing down. I have an okay laptop. 3.1GHz (8 CPUs) and 12GB RAM. Like I said, 4.7 runs just fine. Tested with the same scene, etc. What is the cause of the slowdown? It's only when I play it. (Simulate, Play In Editor, Launch)
Thank you very much for reading this!

Try debugging it using the built-in debugging tools. I had a similar problem once with creating UMG widgets every frame after about 5 minutes it would get down to about 1FPS until i stopped "playing" i had to use the debugging tool to find out what was causing the slowdown and traced it to my blueprints.
