Isn't there a build of Wine made specifically for playing Overwatch? I tried it a while ago and it worked really well.

It looks like there is now a report on appdb with a gold status, every time I checked it before it was borderline unplayable. Even now the gold report says it has constant flickering and fps drops. I'll probably try it, but knowing blizzard's tendency to completely break wine compat with some updates I really wish the support was first-party.

If Blizzard released their games on Linux I'd be incredibly happy. Most of the time I boot Windows 10 it's to play Heroes of the Storm.

Have you had any luck running it with Wine?

I'm not parent, but Overwatch runs very well on my computer with Wine + DXVK (Wine plugin(?) which translates DirectX to Vulkan). Performance is not noticeably worse than Windows.

Edit: I realize you may have been talking about HotS, not OW, but according to Google that should also work if you configure esync: https://github.com/lutris/lutris/wiki/How-to:-Esync

If you have a laptop with switchable graphics, you will need to use nvidia-xrun to enable Vulkan passthrough to the dGPU, but aside from that I just followed these instructions: https://github.com/lutris/lutris/wiki/Game:-Overwatch

Note that the Blizzard app will fail to launch with DXVK enabled, so you have to disable DXVK, launch Battle.net, enable DXVK, and then click the 'Play' button to start Overwatch. I made a few scripts for this, so I just do `./disableDxvk ... ./startBlizzard ... ./enableDxvk ... click play` to run the game.

  WINEPREFIX=~/.overwatch_wine/ setup_dxvk64 # enable DXVK
  WINEPREFIX=~/.overwatch_wine/ winecfg      # disable DXVK: delete the overrides from Libraries tab
  exo-open Battle.net.desktop # launch the Blizzard app, the .desktop should be generated on install
