Vulkan Mode
In our Android 9+ versions, we include the ability to use a Grub command for enabling Vulkan mode on supported graphics hardware.
When your PC reboots, it's initially shows a grub menu. tap "e" to edit the current selection and add the VULKAN=1 to the end of the line that starts with "kernel", then follow the on-screen prompts to boot with those edits.
If it works, then edit Grub from your main OS, and add the flag there.
