One of the big issues with virgl OpenGL is that all OpenGL apps on the virtualized guest, do share single OpenGL context on the host and single queue between the two. This causes a lot of stutter when one more than 1 OpenGL is running on the guest. For example, running Unigine Heaven I get about 95 fps, but if I also run glxgears (with vsync 60 Hz), the Unigine Heaven performance drops A LOT, to about 45 fps, and there is visible stutter. virgl vulkan will solve this problem, by using multiple queues and logical devices, which are easily supported by Vulkan API and drivers, even from a single userspace process (like qemu). The zink itself does of course isn't 100% performance of the native OpenGL drivers (like radeonsi), but it is pretty close. In fact in some benchmarks and tests, for example supertuxkart, zink+radv gets 99-102% of radeonsi, which is amazing). In most others, the 65% is average I see across many benchmarks and titles (usually 55%-75%, with very few benchmarks where it gets more or less than that).
for the longest time I've wanted a Linux phone, that would run Android in a VM. with respectable performance. And Vulkan video is pretty much the last big thing that would be needed for that.
of course assuming that the android guest could use zink. virtio can handle literally every else. then you could swap between a linux environment and an android one. with very little preformance overhead.

but i think virgl vulkan to zink, will be faster than just regular virgl

The issue is that vulkan is still optional, however, what may be smart (I don't know?) is to build a tree or for package maintainers to make group "mesa3d" for example (or something like that) that would include all implementations (GL, VK, CL etc.) while allowing separate installation as it is the case now. Just trowing this out there, maybe it's a good idea, maybe terrible.
In that case, for compatibility purposes I guess mesa3d-demos would be a name that would include all demos for example. Or simply include it in mesa-demos (at the risk of having non-functional demo in the group).

An interesting phoronix benchmark could be:
zink running the raylib gl demos with maybe patches for fps counting, and then nvidia driver vs radeon ?

Wine own internal dos emulation is not that good. Wine project started external project called dosbox most of the time they have specailised in dos application compatibility then after while the default action for wine came use dosbox and only use wine own implementation if that did not work.
A few years latter we are using 64 bit systems the v86 mode of the Linux kernel is gone so wine own internal dos emulation cannot be run for dos applications because v86 mode is a required feature so it works. So wine own dos emulation sitting their for win3.x and before applications so now when you run dos applications with wine is basically a proxy to dosbox and dosbox has picked up a few features to work better with wine.
