I have been having problems with version 19 (2018) of photoshop CC. Ever since I installed it, it has caused my system to run slow. When I observe the task manager during opening of photoshop I see the system CPU usage goes up 10% (photoshop CPU and memory usage appears reasonable but system use spikes) and my laptop seems to be thinking very hard. It causes mouse clicks to lag and I regularly get the rotating blue circle cursor. It is basically unusable like this. My laptop runs windows 10 and is reasonably high end. Photoshop 2017 (v18) runs great with no issues. My graphics card driver is up to date.
I know others have had issues but none seemed to match my symptoms. Any ideas?
Please try to temporaly disable "use graphics processor" and check if photoshop run better.
Thanks Francesco, tried that but makes no difference.
