This is probably more common than you'd think, at least in my anecdotal experience. Converting directx commands to vulkan commands, especially for AMD GPUs, can result in better and more consistent performance on Linux.
Do you have any numbers or examples of games? I know that it's generally the case that DX9 games often have greater performance through DXVK, but DX11 and DX12 should usually be a little bit slower. Also, CPU-bound games are often faster on Linux in my experience, but it's rare for games to be CPU-bound (MMOs etc).
Additionally, OpenGL and Vulkan should be faster on Linux (Native or WINE+OpenGL/Vulkan), but I don't have as much experience with them.
Edit: I found this video which has a few standout games where Linux pulls ahead even on DX11/DX12. Hopefully that's a sign of future trends.
There was a tweet before the recent Cyberpunk update that essentially said "expect very high CPU utilization as we now use the whole CPU" which I thought just meant they dropped the ball somewhere.
I haven't done extensive testing on this as I'm just some dude. It's been a long time since I've had windows running on anything, but the three that I remember are:
