I have an Acer Aspire 3 A315-53.
It's a core i5 7th gen with 12GB RAM.
I started using this laptop last year in December and I was able to play games like GTA 5, Max Payne 3, Blur, Darksiders, WWE 2K17,MK XL and a lot more old games on medium settings and they would run smoothly.
In April this year, I had updated to the latest version of windows 10 21H2 and I also updated all my drivers. A week after doing this, I noticed that all the games started lagging all of sudden for about 3 to 5 seconds continuously. I did lots of tests such as hard drive and memory diagnosis but the problem continued. I decided to do a clean installation of windows but even after doing this, I'm still facing the same problem and it's very much annoying. What can I do?
