I am using a high-end AMD desktop. 2700X+32GB RAM. It was getting slow this year. I tried it on a fresh Windows 10 with CC 2019 and CC 2020.
When I clicking different photos you can see it takes about 2-3 seconds to load the next photo. They are not 100MP photos, they are just 24MP small RAW files. The same files on cheap Intel laptops are much faster than AMD.
The funny thing is. If I am using a portable PS, without lens and color profiles. It runs really fast on my same AMD computer!
So I have to say the cracked PS is better than the Real PS?
