It did take from basically 2007 to 2011 to do the design and many dev runs through what is now Global Foundaries as the way GPUs are produced when manufactured into silicon by a foundry is fairly different than CPUs, so finding a working medium between those two processes took many failed attempts, pretty surprising they were able to do it in less than half a decade!

Also soon the asahi graphics driver will run vulkan and fex has seen great improvements recently. It wouldn't surprise me you can get steamdeck levels of compatibility with games.
