shmerl: So it shows that eON already supports some DX11 games. Virtual Programming are the ones who are working on the Linux port of the Witcher 2, and they already improved it quite a bit. But I really hope CDPR won't use any wrappers if they are to make a Linux version of the Witcher 3 though.
silviucc: If by "improved" you mean that they barely managed to get equal performance to the other contender which was wine + csmt patch, then yup, they're kicking arse and taking names alright.
It surely improved quite a lot since the first release. So if they'll continue improving it rather than stop now, they still might get a decent result.
Coelocanth: Again, I'm not convinced this scenario is likely to come to pass. At least not anytime soon.
Such scenario is easy to predict. SteamOS / Steam Machines gain traction. More developers start making games for Linux. In turn it improves drivers, boosts OpenGL usage and development and increases Linux user base and etc. and etc. Same network effects that MS themselves used to gain a dominant market share. And now the same thing can turn against them. It won't obliterate Windows, but it surely can significantly increase competition, and MS are scared of competition because they aren't used to it on the desktop.
