I changed resolution on csgo 2-3 weeks ago. When i wanted to change back i started to lag on every game and can only play on that res on cs without lag. I was playing on 1920x1080 before.
Ive tried valorant which i ran smooth a couple of months ago.

Ive tried to reset my computer, update cpu driver, ran tests on the cpu, scanned for virus and vacuumed most parts of the computer.
Thank you
