So basically I upgraded from windows 7 to 10 few days ago before that I had no issues. I also installed an SSD and new 16gb ram and installed OS on SSD.
I have my 144hz as my main monitor and a secondary monitor with 60hz with an HDMI cable plugged in since my gfx card only has 1 port. I never had an issue with this before but as of now I've noticed how tabs load in slowly and how they really lag when you move them I'll provide some short clips and you can see how it looks. Also videos / streams kind of lags small stutters and the video speeds up randomly it kind of looks like the computer can't keep up with the video.

At first I thought it was that I needed to install graphics drivers, adobe but I've done all that. I felt a difference when I unplugged my hdmi monitor but it still doesn't feel 100%.
