WinBoat's Helios VGPU: What It Is (and Isn't)

WinBoat's Helios is an API-level paravirtualization tool for 3D GPU acceleration in virtual machines, not a traditional vGPU. It forwards graphics calls from a guest Windows system to the host Linux GPU via a custom Vulkan driver and virtio channel, meaning guest applications lack direct GPU access and cannot use CUDA, NVENC, or DXGI.
