Steam games are sadly very hit and miss. In my case more misses than hits.
Yeah. I hesitate to be harsh on a volunteer project. It’s clearly got a lot of brilliance behind it. But yeah, all the games I tried today failed to run unfortunately.
On the other hand, the Steam launcher itself somehow runs faster via Whisky than the native Mac version.
whisky does run steam but in my particular case, trying to download a game, it stops at 2%. and that's it. it does not seem to happen with crossover.
