Vulkan is coming to Raspberry Pi: first triangle
Following on from our recent announcement that Raspberry Pi 4 is OpenGL ES 3.1 conformant, we have some more news to share on the graphics front. We have started work on a much requested feature: an open-source Vulkan driver!
Standards body Khronos describes Vulkan as "a new generation graphics and compute API that provides high-efficiency, cross-platform access to modern GPUs". The Vulkan API has been designed to better accommodate modern GPUs and address common performance bottlenecks in OpenGL, providing graphics developers with new means to squeeze the best performance out of the hardware.
Be warned that the effort could take months or even years.

Can they fix the hardware issues first?
I'd rather they fix the passive cooling issues with the RPi4 that cause the thermal throttling during multi-core tasks and the damn non-standard USB-C cable crap.
I'm really not trying to be to be a Negative Nancy, and I really DO like these SBCs. Things were really going so well each new generation of the boards, until version 4.
Hopefully they will fix these things in the next board release, but in the meantime, I really struggle to have any excitement over this news like I would have in the past.

Temperatures are lowered with the latest firmware updates. I usually run less than 50°C in a FLIRC case, so no throttling in sight. Plastic case with no cooling? Yes: [jeffgeerling.com]
Cooling Option / Min Temp (°C) / Max temp (°C) / CPU throttled?
Pi in official case (no fan) / 51 / 82 / YES
after fw update / 43 / 76 / NO
"USB-C cable crap" affects almost nobody [tomshardware.com].

Can firmware really do that? It sounds more like they just throttled back the board overall. I cannot imagine a firmware update that somehow caused a 0 fan device to passively cool faster or run all code more efficiently so as to create less waste heat.

It looks like performance has stayed the same or improved by throttling less during stress tests.
Here, you can watch them go through every update (never seen this blog post, it's great):

It's rumored that the 1.2 hardware revision fixes the USB-C issue, but there's no official confirmation of that and it could be difficult to find the latest revision without running code on it.
