Options for Graphics Acceleration

[kakuni]

By default, the CPU does all the drawing for the virtual machine's display.
Is there any options to accelerate this process by GPU?

Many people want to use GPUs to improve the graphics performance of their VMs.
Most articles on the Internet showing how to do this mention GPU passthrough.
Some also mention virtual GPU sharing, such as SR-IOV.

GPU pass-through not only consumes one GPU per VM, but also has other problems.
Virtualization-enabled GPUs are only available to financially strong companies.
Neither method is available to individuals!

I don't want to run high graphics performance demanding workloads like games or 3D CAD on my virtual machines,
I just want to make browsers and other desktop experiences just a little bit more comfortable than if everything was handled by CPU.

Radeon-only or GeForce-only methods are welcome.
Thank you in advance.

You are basically limited to PCI passthrough or VirtGL (still very experimental and only for linux guests if I remeber correctly...you might want to di some research on this...) with VMs.
LXCs would be able to share GPU acceleration.

I hope in the future someone will fork the Intel ARC consumee GPU drivers and add SR-IOV support like they did with Intel iGPUs.

Dunuin, Thank you for your response.

Currently, it seems that VirGL (VirGL GPU in Proxmox UI) is the most promising way to meet the purpose.
However, Intel CPU's internal graphics seems to handle it in my Proxmox host.
How can I configure it to process VirGL on a more powerful dGPU?
