Yes, thank you very much for your response. This is exactly where I am right now in a discussion with ChatGPT. I even tried running the
GPU Caps Viewer Demo inside the Windows 10 guest, but it didn’t work as expected.
The fundamental issue is that I cannot do
GPU passthrough (VFIO) because my notebook has only one GPU:
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Lucienne (rev c1)
This is an
AMD APU, which combines CPU and GPU on a single die. On laptops, this presents multiple limitations:
The GPU is always required by the host for display output, so it cannot be exclusively assigned to a VM.
Laptop iGPUs/APUs generally cannot be hot-unplugged or re-initialized for passthrough, unlike desktop GPUs.
VFIO passthrough typically requires either a second discrete GPU or a dedicated PCIe device to achieve native-like performance in the VM.
Because of these hardware limitations, all my attempts at GPU passthrough turned out to be a dead end.
Given this, there are realistically only two options left for me:
- Trying Wine or Proton to run the games in Linux directly (which caused stability issues such as freezing and rendering glitches).
- The most practical approach: reboot the notebook into native Windows, where all RPG Maker games run flawlessly, leveraging the APU directly with no virtualization overhead.
In summary, while VM gaming is theoretically possible with VFIO/GPU passthrough, laptop APUs with a single GPU make it infeasible, and for my use case, native Windows remains the only reliable solution.
