I installed Zorin OS Core today. And it was laggy a bit from the start. Then it stopped and now it started again. When I’m in apps and when I scroll it laggs. Especially in Firefox. I reinstalled a fresh PC and I don’t have dual boot. My specs are:
Intel Core i5-6600
2x8GB DDR4 2133MHz RAM
256GB SATA III SSD
GTX 1060 6GB GPU
When I had Windows there were no such lag. And my memory usage is anywhere from 4GB to 6GB and CPU usage from 20% to 40%. So that’s not the problem.
