After Effects slow with two monitors

I'm using a 1440p 165hz monitor along with a 75hz 1080p monitor, and whenever I go into after effects, it has a hard time rendering a video that I just dropped in. When I unplug my second monitor, the 75hz one, suddenly after effects can render the video in real time.

 

I have an rtx 3090ti, 32gb ddr4, Ryzen 9 5900x, so what could be the problem?!

Heterogeneous monitor setups are awful. Nothing to do with AE. It simply comes down to your GPU having to do a lot of extra work to accommodate both screens and it gobbles up all resources because buffers need to be doubled, redraws calculated multiple times etc.. Aside from fiddling with the graphics driver the only real fix really is to use identical monitors.

Ah, I've got around the problem by simply unplugging it when editing.
