It must be very hard to exactly compare games between Windows and Linux because it’s possible that emulation in Proton, WINE or the driver means some settings or extensions might not be enabled even if they appear to be. DirectX emulation is also bound to slow things down so a game probably has to be use OpenGL or Vulkan directly.
So while I can well believe that Linux can keep up and possibly exceed Windows, it needs a careful technical eye to ensure a true comparison is happening.
Wine is not an emulator
Wine is an emulator. It might not have started as such when it was winelib but it is now, especially when running binaries. If in doubt read their own FAQ where they take pains to describe it depends what you’re doing and what is meant by emulation.
