Stuttering is driver related
The card might be fine, but the AMD driver in a VM, has issues.
Had to use DDU to remove the driver, to get the settings to work. Opening the settings for the GPU did nothing. Did the driver work when Windows wasn’t in a VM?
Switching to NVIDIA may not work, I had a NVIDIA card, sold it because MSI removed support for it from my board, at least if you have a AMD card too. Didn’t try it being the only card.
I might remove the current one, and try getting the one Windows installed back. That driver might have less stuttering.
If I sell my laptop, I could buy a video card. Buy it on Amazon, so you can send it back, if it isn’t compatible with your motherboard.
