I was gone for a weekend then when I came back my fps in csgo had dropped by over 45%. I started by looking for malware, but came up empty. Then, I looked at my usages from my GPU and CPU and realized I was maxing out my CPU and getting less than 50% GPU. So, I don't know what to do...

Thats exactly what I was thinking. I don't know what happened but it basically makes my 144hz screen obsolete.
