I can't use #Wayland with my #Linux system. Performance is terrible.

I have a 2021 Lenovo P17Gen1.
It has both an Intel P630 and NVIDIA RTX3000 Mobile GPU, running as a Prime pair.
It has a 4K eDP display, and two LG 4K displays, one connected via USB-C, and one via DP, via a TB3 Dock, all running at 60Hz.
It has 128GB of RAM, and 4TB of striped BTRFS SSD.
I am running the latest #Hyprland.

I tried running on #Arch, which cut the frame rate worse than half ANY time I connected an external 4K display ANYWHERE on either the laptop, or dock, DP, or USB-C. It refused to work via HDMI.

Switched to #Ubuntu and use Koolit's #Ubuntu installer for Hyprland. Performance is close to 60fps, but not quite. Stutters, and OBS runs at an average of 10fps, regardless of whether #PipeWire is in use, or not. Unusable.

I have been a #Linux user since September of 1991, and I can't even begin to know where the F**K to go to even diagnose this problem, due to the sheer number of variables.

Is it the NVIDIA drivers?
Is it Wayland?
Is it Hyprland?
Is it Pipewire?
Why is the performance better on #Ubuntu than on #Arch?
If I were to use Wayland, what COMPARABLE GPU would I use instead?
Do I just completely jettison using a laptop and build a workstation instead?
Why in the flying F**K can I not get stable vsync?!

I am posting this, because I am genuinely looking for knowledgable answers from knowlegable people, and I am _VERY_ concerned, that given the mass exodus from Xorg to Wayland, that I need to figure out something before I end up with a system configuration that is unusable.
