I've tried everything to get it to run smoothly, I've restarted my computer, I've uninstalled and reinstalled it, I tried increasing the performance, I tried updating my graphics driver, I uninstalled and reinstalled my drawing tablet driver, I tried clearing the cache, I tried updating windows and then undoing the windows update, I tried having absolutely nothing open in my computer except photoshop but it still runs SUPER slow.
It'll take more than 5 seconds to do a single brush stroke. It used to work just fine, I really don't know what changed to make it do this. I don't think its system requirement issue, because it used to run just fine on my computer.
Is anyone else having this problem? Is there anything I can do to fix it? I have a nitro boost computer, windows 10 version 21h2, a Huion Kamvas 12 drawing tablet and photoshop version 23.5
