Trooper1270: Thanks!, that's great to know (oh, I never alt+tab out of a game, and just exit when I'm finished)... By the way, which version of Wine did you use to test ? (I'm using 4.0.3 stable).
0bpm: I'm using the Wine version 5.5 provided by Lutris, DXVK and esync are enabled. I haven't tested with older versions.
Thanks again for the info. I have Wine (bare-bones, without any other supporting software) installed via a PPA added to my sources list, but have decided not to keep it up-to-date for quite some time, because the current version has been working fine for me so far. Though it's great to know this game does work in Wine, and that I have the option to update to a more recent Wine version (that does work) if the one I'm using causes problems.
Anyway, say safe and all the best.
