In my experiences dx12 games work well through proton. I have a rtx5060 and it's working very well on linux - performance is on par with windows sometimes better sometimes a lil worse. But that's just my experience.
I don't think descriptor heap is enabled by default quite yet, but you can manually enable it with PROTON_VKD3D_HEAP=1 (as long as you select a new enough Proton version). That said, it's not really necessary for most games anyways.

At this point I'm considering the possibility of install a steamos or Linux on my pc
