Hi,I am currently using niri + dms and Plasma on CachyOS, but I am running into some weird refresh rate issues with my monitors.
in the terminal /settings it says i am on 180 or 300 but it was feeling laggy so i tested it on UFO frame rate tester on firefox.
On niri I am only getting 60 FPS on both my main monitor and my 2nd monitor.
On kde I am getting 300 Hz on the built-in monitor, but still stuck at 60 on the 2nd monitor.
I checked the wiki for niri and tried to set it up for a dual GPU system by setting render-drm-device "/dev/dri/renderD128".
When I set it to NVIDIA, the 2nd monitor works, but the built-in monitor shuts off completely.
When I use Intel on both, I get 60Hz on both, OR I can get 300Hz on the built-in only if I completely disconnect the 2nd monitor.
i could not find the same issue and When I asked an claude about it, it said it's a driver limitation.
Is there something I can do about this, or am I missing someting?
