Well this is not an ideal situation. After much petitioning CDPR finally acknowledges Linux users, but their game version is not what we expected.
I think Linux users should be both critical and moderately grateful. CDPR doesn't know how to approach Linux development but we want them to learn, not ditch this as a failed experiment.
In principle, it's the same as how we were before, using a third party. Except it might be easier to run by non technical Linux users. On the other hand, it performs badly, much worse than using Wine.
I wouldn't buy it on Steam but I think we should try to be supportive and provide critical feedback, not just bitch and whine (wink wink) about it. Also CDPR should humbly accept the incoming (or ongoing?) shitstorm, keep their cool and not pull a Bioware: be grateful you dirty peasants! Not that they would anyway, just saying.
It's a start. I hope we can somehow contribute to making it better. I really want a fast, native and fully featured Witcher for Linux.
