so whats your experience between vulkan and directx12?

I've been using Vulkan with great success ever since it was introduced.
Mind, I'm playing on Linux so Vulkan is a natural choice, since there is no native DX for Linux (yet. I heard somewhere MS might be working on that.).

I tried vulcan before it was updated and it crashed.
I found it to crash after updates months ago and it crashed.

switched to dx11 until now, retried vulcan which is out of beta
and CTD twice within minutes on the same map.

switched to dx12 still using it. no crash yet (lower performance
than vulcan but does not crash which is obviously the key.)

not sure if dx11 or dx12 is best for my old gtx 660. vulcan is not.

Vulkan seems not to run on the GTX660, specifically ones with 2GB. That's what a short search brought up, anyway.

Can't tell any difference. Old eyes. 4+ year old equipment. Hope it works better for someone, because it's wasted on me.

My graphic settings are all low and using windows 10.
DirectX11, fast map loading, no crashes.
Vulkan, feels 3D and movements seems slowed.
DirectX12, feels like POE2, very 3D strangely good that I check my graphic settings which is the same, but slowest map loading and most crashes.
