The most basic requirement to make use of Looking Glass is to have a system
with two GPUs, the following configurations are valid:
* Two descrete GPUs (dGPU)
* A descrete GPU and an integrated (iGPU) such as is common in laptops.
* A descrete GPU or iGPU and a virtual GPU (vGPU) as supported by some
* Two discrete GPUs (dGPU)
* A discrete GPU and an integrated (iGPU) such as is common in laptops.

Looking Glass aims to achieve the lowest possible latency and as such it
is important that you do not overload your system. The minimum recommended CPU
to obtain a decent expereience with Looking Glass is 6 cores or more, with
to obtain a decent experience with Looking Glass is 6 cores or more, with
Hyper-threading (>= 12 threads).
PCIe bandwidth can also be a limiting factor, as such both GPUs should have a
minimum of 8 lanes (x8) at PCIe3 speeds, or 4 lanes (x4) at PCIe4 speeds.
The GPU used for the guest virtual machine must have either a physical monitor
attached to it, or a cheap dummy plug. The guest operating system (most notibly
attached to it, or a cheap dummy plug. The guest operating system (most notably
Windows) will disable the GPU output if there is nothing attached to it and
Looking Glass will not be able to function. If you are using a vGPU the virtual

NVIDIA unlike AMD do not seem to suffer from the same stability issues as AMD
GPUs when operating as a passthrough GPU, however due to the closed source
nature of their drivers NVIDIA can not make use of the DMABUF feature in the
Linux kernel and as such it is not recommended for use as the host GPU.
