Everything is very slow. Applying a drop shadow and tweaking it is very laggy. My 2013 iMac does all of that very smooth.

When I am drawing just simple things, the MacBook Pro gets very hot very fast and the fans go crazy.

In the 2015 Version it is a bit better but after a few minutes, the MBP gets hot as well.

What I tried so far:
  • reinstalled all Adobe software
  • created a new user and testet all of it again
  • changed resolutions and disabled true tone
  • smc, pram reset
  • formatted the hard drive and reinstalled macOS
Here tried to capture the issues:

Maybe your PC has just some dust inside so cooling does now work as it should. Because if there is too much heat PC decreases CPU frequency so it became slow even for simple tasks and shows 100% CPU usage. Just idea. Try to find a way how to measure CPU frequency.

Thanks for the reply.
First it is not a PC but a unibody MacBook Pro. It ist half a year old so I doubt that dust causes the issue.

Reinstalling PS does not install a new Preferences file. It may be corrupted and part of the problem. Try resetting it as outlined at the below link. If that doesn't fix it try the suggestions at the 2nd link.
