Stutters when second monitor is plugged in, but is off

I have two monitors, my main one is 165hz and the second is 75hz. I'm on an Nvidia card, using Xorg, and the only way I can actually achieve 165hz on the main is by turning off the second monitor. Now: unplugging the monitor works fine, but I obviously don't want to do that. I'm using bspwm, so I included a

xrandr --output HDMI-0 --off

, which does turn off the monitor, but creates massive stutters every 5 seconds. While troubleshooting, I also noticed the xrandr command is not even the issue. Having removed the line, I tried plugging it back in, but without setting it up in bspwm or refreshing the config, and the stutter still goes on. I'll post my bspwm config but apart from that I don't know what logs would be useful, so please feel free to ask and I'll post them. Thanks!

bspwm config:

#! /bin/sh

pgrep -x sxhkd > /dev/null || sxhkd &

#gaming
bspc config remove_disabled_monitors true
bspc config remove_unplugged_monitors true
bspc monitor DP-2 -d 1 2 3 4 5 6 7 8 9 0

#bspc monitor DP-2 -d 1 2 3 4 5
#bspc monitor HDMI-0 -d 6 7 8 9 0 

bspc config border_width         4
bspc config window_gap          12

Sounds like https://bbs.archlinux.org/viewtopic.php?id=286115 (unresolved, but a bunch of things you can try)
And try w/o picom.

I tried killing picom, no change.
I checked out the post you sent, but the user's issues seem to come from the fact he's using a laptop with iGPU and dGPU (?). Is there any logs I can send to try and narrow down the issue? Maybe my problem is different from his.

Re: Stutters when second monitor is plugged in, but is off

Xorg log and "xrandr --verbose", possibly "printenv"
Do you have the same issue if you run the main output at 75Hz as well?

Re: Stutters when second monitor is plugged in, but is off

That's an old xorg log, see https://wiki.archlinux.org/title/Xorg#General and pick a log that represents your current active session.
