Re: Only have one thing to say to Lenovo....
Ok, let me just have a look at a few games I've been playing recently without problems on Windows:
Subnautica: Apparently it will work under Wine "99%", after a bunch of fiddling. So it's a starter, but clearly not up to par.
Forza Horizon 4: Nope, unsurprisingly for a Microsoft game, no one seems to have got this working on Linux
FTL: Has a Linux version, so all good. (Although you might need to disable PulseAudio to prevent it locking up)
Surviving Mars: Also seem to have a Linux installer (if you buy from GoG).
The Bradwell Conspiracy: No mention of it anywhere on the internet, but it's just come out. I'm going to chalk this down as a 'probably not'.
To sum up; a lot better than I was expecting, but still only about 85% of the way there.
