DCS World 2.5, DCS World 2.5 Open Beta, and DCS world 1.5 now all install and launch properly in the recent version of wine-staging with dxvk installed. When one goes to enter a match or mission, it does not crash, but there are shader issues that render the game unplayable. Hopefully this means that soon, DCS will run properly in Wine, because just launching and entering a mission is a huge step up from where it was before.
