Most AAA titles are on DX12 now. ID is on Vulkan. E-sports titles remain largely on the DX11 camp. What the modern APIs give you is less CPU driver overhead and new functionality like ray tracing. If you're not CPU-bound to begin with and don't need those new features, then there's not much of a reason to switch. The modern APIs require way more management than the prior ones; memory management, CPU-GPU synchronization, avoiding resource hazards, etc. Also, many of those AAA games are also moving to UE5, which is basically DX12 under the hood (presumably it should have a Vulkan backend too, but I don't see it used much?)
