Great benchmarks. Thanks for including the R9 290 Michael, lots of us still using Hawai GPUs. It's unfortunate the development effort has stopped to move the amdgpu work past experimental.
But still fantastic to see it as a 5 year old GPU performing so close to the gtx 1060. The aftermarket models are even quicker as they maintain higher clocks without thermal throttling.

Dxvk spoofs an AMD GPU by default because compability reasons (nvapi) so at least the games code path should be the same.

I strongly suspect DXVK disables certain Direct3D 11 features for AMD GPUs that's why they end up running faster in Linux than in Windows.
I am a bit perplexed by his frame time chart though. If I am reading it right, it should be inverted.

Also, I hate to be that prick, but Wine is not an emulator (but you already knew that I guess)

Vega64 at 1440p:
On Windows: 51.2FPS
On Linux: 65.1FPS

Hitman 2 is partially not well optimized for Radeons, they lose quite a lot of performance in some foliage intense levels vs. Nvidia. On Windows, Radeons perform well in the Miami Formula 1 level as well.
But great to see that DXVK + RADV deliver top notch performance here.
Regarding the verdict which framerates are playable: Kinda disagree, just set dxgi.maxFrameLatency = 1 in dxvk.conf to get lower input latency and better frametimes at usually just a very slight fps loss. I play the old Hitman 1 levels in Hitman 2 on an RX 580 without issues in 1440p. Just the stupid screen space shadows (which are basically invisible), ultra LOD setting and reflection quality higher than low are a problem, but the game usually still looks very good with that tweaking anyway.

Nice benchmarks. Thanks!
I get around 50fps (don't remember the exact number) with my Fury running 1440p medium-ish, but the benchmark is quite heavy compared to the real gameplay, so I'd say the game is perfectly enjoyable even when the benchmark shows numbers slightly below 60fps. It's not the type of game that demands insane frame-rates to be enjoyable either, and it looks good even on moderate settings.
