Yes it’s because of something called frame pacing

I’m running at 1080p 60Hz to keep the PC as silent as possible. Though I generally don’t play games where it’s useful (or easy) to have higher refresh rates. Maybe I should look into GPU cooling solutions again, but finding something that fits properly can be difficult. Should probably get new glasses first, anyway.

Doooo it, you can get a high refresh (>= 165 hz for less than 100$
