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.

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

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):
