So I have a weird issue I was wondering if anyone else has, or knows a way to fix it. So I have two monitors, my main monitor which I use to play RuneScape it's a 144Hz 1920 x 1080 1MS panel from LG, and my secondary monitor which I want to use to watch YouTube or Netflix ideally, it is a 60Hz 1920 x 1080 1MS panel from Asus, it's older than my main that's why it's only 60Hz. Now when I am tabbed into RuneScape anything on my secondary monitor runs at like 1FPS and freezes and stutters until I tab out of RuneScape which then causes it to catch up. I have tried RuneScape in windowed and fullscreen, I have tried RuneScape with VSYNC on and off, but I can't figure out what is causing it. RuneScape is also the only application that causes this issue.
