QEMU Direct3D Encore -- MESAGL Pass-through & Virgil 3D -- Windows 10 Host
12An encore with Direct3D using WineD3D. MESAGL pass-through uses QEMU enhanced WineD3D libraries made to be compatible with legacy 32-bit Windows 98/2K/ME/XP VMs. The enhancements cater for improved game experience and compatibility such as scaling for games only supporting 640x480 and frame rate limiting to keep the game physics intact on fast modern system. Virgil 3D simply uses the bundled WINE package from any modern Linux distros.
The major advantage of running Windows VMs is that WINE is only required for Direct3D support and limited to a handful of libraries in contrast to full WINE suite of libraries required for Linux VMs. Switching to different versions of WINE on Windows VMs is simple and straight-forward by per-game DLL replacement, ie. different games can make use of different WINE versions on the same Windows VMs. For Linux VMs, switching WINE version isn't as simple and many would rather use the same WINE version for all Windows games.
3DMark2003 is DirectX 9.0 shader-based benchmark. GPU shader-based workloads are leaning well towards GPU virtualization and both scored respectable level of performance that rival high-end systems back in year 2004 based on GeForce 6800 and Radeon X800, on thin & light 15W TDP 2018 model Ryzen 2500U laptop. So everyone can literally enjoy retro Windows games on any modern systems with state-of-the-art CPU & GPU. Just say goodbye at keeping old Windows PCs for games.
