I don't know if it's an issue with my monitor or display drivers. I recently bought an AOC 1440p 144 Hz monitor, and it's been great.
However, after playing a game for a couple hours and returning to the desktop, I can clearly tell the refresh rate is no longer at 144 Hz. Sometimes it feels like it's back at 60, other times its really choppy and feels even lower, possibly at 30 Hz. I can tell just by dragging my mouse across the desktop.
It's not getting hot so I don't believe it's overheating.
