Drastic performance change when plugged into charger

[kelvinhall05]

Describe the bug
If fusion360 is started while my laptop is on battery, any graphical stuff (2D or 3D) is horrendously slow (1FPS or so). However, if fusion is started while plugged in, or the charger is plugged in while fusion is running, performance speeds up to what I would expect for my hardware. This good performance continues even if the charger is unplugged.

To Reproduce
Steps to reproduce the behavior:

1. Start fusion on battery
2. Observe poor performance
3. Plug charger in
4. Observe good performance
5. Unplug charger
6. Continue to observe good performance as if plugged in

Expected behavior
Consistent good performance

Desktop (please complete the following information):

• Unsure of version number; latest as of writing this
• Thinkpad T14 Gen 3 AMD w/ Ryzen 6850u and its integrated graphics
• Arch Linux
• KDE
• DXVK but I tried DX11, DX9, and OpenGL and all have the same issue.

Additional context
This obviously sounds like some sort of system-wide battery performance limitation, however, I've tried disabling TLP and everything else I use to manage performance to no avail. It seems to be something within wine and/or fusion.
