In fixed pass-through or GPU pass-through (a special case of PCI pass-through), a GPU is accessed directly by a single virtual machine exclusively and permanently. This technique achieves 96–100% of native performance [ 3 ] and high fidelity, [ 1 ] but the acceleration provided by the GPU cannot be shared between multiple virtual machines.
It requires an external pass-through VGA cable hooked up from the 2D card into the Voodoo card’s passthrough VGA port. [ 1 ] [ 2 ] [ 3 ] The Voodoo2's third chip was a second TMU that allows a second texture to be drawn during the same graphics engine pass, and thus with no performance penalty.
SteamOS is an Arch Linux-based Linux distribution developed by Valve.It incorporates Valve's video game storefront Steam and is the official operating system for the Steam Deck, Valve's portable gaming device, as well as Valve's earlier Steam Machines.
Full GPU virtualization (GVT-g): the GPU is shared by multiple virtual machines (and by the host machine) on a time-sharing basis using a native graphics driver; similar to AMD's MxGPU and Nvidia's vGPU, which are available only on professional line cards (Radeon Pro and Nvidia Quadro)
A BFG Physx card. PhysX is an open-source [1] realtime physics engine middleware SDK developed by Nvidia as part of the Nvidia GameWorks software suite.. Initially, video games supporting PhysX were meant to be accelerated by PhysX PPU (expansion cards designed by Ageia).
General-purpose computing on graphics processing units (GPGPU, or less often GPGP) is the use of a graphics processing unit (GPU), which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit (CPU).
Mod packs are groups of mods put into one package for download, often with an auto-installer. A mod pack's purpose is to make it easier for the player to install and manage multiple mods. [ 73 ] Mod packs may be created with the purpose of making the original game more accessible to new players or to make the game harder for veterans to enjoy.
Steam Deck runs SteamOS version 3, based on the Arch Linux operating system. While SteamOS had been previously developed for Steam Machines using Debian Linux, Valve stated that they wanted to use a rolling upgrade approach for the Deck's system software, a function Debian was not designed for, but which is a characteristic of Arch Linux.
