UTM Ships Triton, a DirectX 11 Driver for QEMU, Pairing With Neptune to Serialize D3D Calls Across the Hypervisor Boundary

The UTM team announced Triton, a new Windows guest driver that — together with the previously released Neptune protocol-forwarding layer for VirtIO — brings full DirectX 11 support to QEMU virtual machines. Neptune serializes Direct3D API calls across the hypervisor boundary; Triton is the guest-side driver that makes a Windows VM see a real D3D11 device. For anyone running Windows-only GPU tooling on an Apple Silicon or Linux host, this is the first credible open path to accelerated D3D11 in QEMU rather than falling back to software rasterization.
