Easy-GPU-PV is a PowerShell project that automates the process of sharing a physical graphics card between your main Windows installation and one or more virtual machines running inside Hyper-V. Hyper-V is the built-in Windows feature for running virtual machines, which are isolated copies of an operating system that run alongside your main one. The GPU sharing technology it uses is called GPU Paravirtualization (GPU-PV), the same approach used in Windows Subsystem for Linux and Windows Sandbox. Without this project, setting up GPU-PV involves a series of manual steps: creating the virtual machine, installing Windows inside it, partitioning the GPU, and copying the correct driver files from the host to the VM. Easy-GPU-PV replaces those manual steps with two PowerShell scripts that handle everything from VM creation to driver copying. You provide a Windows ISO file, set a few parameters like how much RAM and disk space to allocate, and the scripts do the rest. The main use case is getting a Windows virtual machine that has real GPU access, so you can use it with a GPU-accelerated remote desktop or game streaming application. The README notes that standard Remote Desktop Protocol is capped at 30 frames per second and should not be used, instead it recommends third-party apps that use the GPU to stream the virtual machine's display at higher resolutions and frame rates. Supported hardware includes dedicated NVIDIA and AMD graphics cards on desktop computers, and Intel integrated graphics on both desktops and laptops. Laptops with dedicated NVIDIA GPUs are explicitly not supported. The GPU must support hardware video encoding, and the Windows version on the host and in the VM should match to avoid compatibility problems. The project requires Windows 10 or 11 Pro, Enterprise, or Education and Hyper-V fully enabled on the host machine.
