Not quite the same thing, but the performance hit when running Windows software in Wine is frighteningly low. Even harder to run games like Overwatch[0] still stand toe-to-toe with their Windows counterparts, which is really surprising considering how many people tried (and failed) to run it at a playable framerate in a VM.

  Im super confused how they benchmarked that. How do you play the same game across two different OS?

    Overwatch lets you save recordings of gameplay a-la Quake 2, and then you can re-play the match at will, even on different systems so long as they're compatible. Looks like they played a match, saved the results and recorded the playback on both systems. It's not exactly the same as playing online (for example, your CPU isn't negotiating networking bandwidth all the time), but it's definitely a level playing field for measuring graphics performance.

  Games are usually CPU-bound. When the graphics additional layers are thin, and DXVK is indeed very thin, there's no reason it will take a huge performance hit.

    I don't know what games you're playing but mine are usually GPU bound.

      Hmmm... makes sense. Even a thin translation layer has a measurable impact then. Maybe the reasonable performance is probably recovered by other parts of the stack.

  Compatibility quirks aside, it really does feel like magic when you get a game running properly!
