Phoronix: VirtGPU DRM Native Contexts Show Potential For Good VM Gaming Performance

At last week's XDC 2022 conference, Google engineer Rob Clark presented on VirtGPU DRM Native Contexts and the potential there for much better performance - especially for gaming - within virtual machines than using API-level virtualization like with Virgl...

Very excited for this, actually looking to find a compatible device when I manage to save up some money, wont be for a while though

Looks cool, but VirDX doesn't exist...

Virglrenderer->Zink->DXVK

Pretty soon we'll have so many layers we'll resemble some geologists' core sample.

Oh we are already there! Pretty much any block diagram of a VM setup looks like a cross section of earth with all the layers labeled!

I would ideally just like to see a software d3d12umd that converts calls to vulkan, then just see venus support in windows

So watching the video all this seems to be about getting Chrome OS to work... I have not had time yet to watch the full presentation so maybe he covers this, but as awesome as getting chrome OS to do this is, does it work with Windows? Specifically can I use something like SolidWorks or Revit with this? And of course will it work with gaming...

I would doubt it.

Nice to see some progress on this front - twice in one day, no less!

I wonder if this is related to Stadia's demise.

If they ever get this working, nvidia at a minimum will fight it tooth and nail. There's a LOT of money to be made from VGPU customers. The only way this would fly with them would be if it had artificial limitations along the lines of a single client essentially doing dynamic binding to the GPU with handoff, i.e. no concurrent usage.

I would doubt it.

It absolutely *should*. Whether it *does* or not is a lot more open to question, but in the abstract this should be close enough to native that you wouldn't even need to step up a tier to get the "right" level of performance.
