I don't know why Steam is rated Runs Well on macOS. For me it crashes slightly after Steam loads properly, complaining about [steam]/bin/gldriverquery64.exe being invalid exe.
A 64-bit exe should fail to run alright, as I'm using a 32-bit Win7 bottle. It's weird that Steam insists on it being present (no you cannot replace gldriverquery64.exe with gldriverquery.exe. Steam finds that out), but I guess I'll have to live with it. How do you guys deal with this problem and continue using Steam?
Using 64-bit Win7 bottle is out of question, as Chromium Embedded 64 doesn't play well with Wine64.
