QEMU OpenGL Duet -- MESAGL Pass-through & Virgil 3D -- Windows 10 Host
15An OpenGL duet of MESAGL pass-through and Virgil 3D at the same time. Both implementation speak the native language of OpenGL and all benchmarks are native binaries in WIN32 and Linux x86 on QEMU 6.1.0 running on Windows 10 Host.
Benchmark matrix:
- Light OpenGL - glmark2 2021.02 "jellyfish" 30-second frame rate
- Medium OpenGL - OpenArena 0.8.8 timedemo
- Heavy OpenGL - Unigine Tropics 1.3 benchmark
No conclusion made on which implementation is superior. There is no conflict of having both at the same time. Virgil 3D runs best with Linux VM and it is SMP ready. MESAGL pass-through works on legacy 32-bit Windows 98/2000/ME/XP VMs offering the flexibility of running good old Windows games in "pristine condition" on the Windows OS the games were originally designed and validated. MESAGL pass-through has the option to enable sRGB visual which brighten up the game with vibrant colors ideal for real-time game streaming and recording. The difference is shown in OpenArena demos. An idle VM in the background does not take up CPU cycles in either cases of Windows XP and ArchLinux32 VMs as both are ACPI capable OSes.
Both implementation enable high GPU utilization over 50% depend on GPU workloads. A "slap in the face" for other PC emulation who once thought GPU acceleration was unnecessary in PC emulation. Oh sure, without GPU acceleration, one can only dream of this level of performance QEMU can deliver today. Or perhaps there is a time machine or an encounter with friendly alien civilization that would bring in technology lightyears ahead of our time.
