First time asking here, I had just recently upgraded to a 144hz monitor due to an upgrade in my PC. The 144fps was great at first. I had then Moved my whole pc setup and did a windows update, then had to leave out of town for the weekend. First time i played when i came back i am receiving stutters as if my CPU was running at 100%. In my HWmonitor my CPU (I7-8700k) was indeed, hitting 100%. I check my task manager, but as soon as i alt-tab out of the game, task manager says my CPU usage is only around 11%, while HWmonitor said it hit a max at 100%. That has not once happened to me since the upgrade. Wondering what i can do to fix these annoying stutters. Thanks everyone.
