Voodoo4/5 and SoftGPU

[Torinde]

What is Bochs currently using as maximum number of threads for the Voodoo3 emulation?
If you enable more threads (readily available on modern CPUs), then probably it'll be possible to reach Voodoo5 levels (see here).

• Materials that may help: voodoo45_spec.pdf, voodoo45_spec.doc, voodoo45_databook.pdf, Voodoo5 ROM v5500.zip (Voodoo5 6000 has a modern incarnation, so surely its ROM was also dumped)

Another avenue for increasing graphics performance is with hypervisor drivers like SoftGPU (Win9x and potentially NT/XP) and viogpu3d (Win8.1+) - can Bochs implement:

• VMWare SVGA-II
• QEMU virtio vga (virgl) - and maybe even expand it with venus/Vulkan

1 thread as far as I know.

If you enable more threads

I suspect it will require large amount of changes and consequently create lots of new bugs.
Meanwhile Voodoo support already have lots of bugs, which wait for fixing for years.
It may be better to port fixes from MAME first, and then start to increase complexity.
