Motivation

Recently I got interested in Blender 3D, partly inspired by infinigen project.

One day I encountered Tellusim. Impressed by the quality of its rendering, I was browsing its blogs and see this. Wow, Tellusim really blowed others out of the water;others including Unreal, Unity, Omniverse and Blender. Wait, Blender is really that slow importing a USD scene?

Since Blender is open-source, why not try to figure out what's going on? Here we go.

First, let's profile it

Ubuntu 21.04 VM with GPU acceleration under Hyper-V...?

Modern versions of Windows support GPU paravirtualization in Hyper-V with normal consumer graphics cards. This is used e.g. for graphics acceleration in Windows Sandbox, as well as WSLg. In some cases, it may be useful to create a normal VM with GPU acceleration using this feature, but this is not officially supported. People already figured out how to do it with Windows guests though, so why not do the same with Linux? It should be easy given that WSLg is open source and reasonably well documented, right?

Well... not quite. I managed to get it to run... but not well.

How to do it?

1. Verify driver support

Proxmox

Find the proper driver at the NVidia website.

Note: Make sure to select "Linux 64-bit" as your OS

Hit the "Search" button.

Scenario

You're running a KVM-based virtualization. You want to do PCI/PCIe passthrough of some device. You don't want it to attach to the host OS at all.

Your device looks like that:

00:1f.2 SATA controller [0106]: Intel Corporation 6 Series/C200 Series Chipset Family SATA AHCI Controller [8086:1c02] (rev 05)
	Subsystem: Hewlett-Packard Company 6 Series/C200 Series Chipset Family 6 port Desktop SATA AHCI Controller [103c:330d]
	Kernel driver in use: ahci
	Kernel modules: ahci
