Even without the need for IE11, BYOND is nigh unusable on Wine. It runs extremely poorly due to extreme and poor usage of Win32 UI stuff.

There appears to be some form of resource leak in BYOND which causes its Ui system to gradually slow down the longer you're playing. This is severely amplified by presumably Wine being less optimized than Windows in these areas. It means that after just ~15 minutes of playing the client will starts stuttering severely on Wine. Then you need to restart the client which can take 2-3 minutes depending on how broken BYOND's ad loading wants to be. (This also happens on Windows but the effect is MUCH slower so you can go hours without noticing).

I remember getting it to work reasonably well with some heavy-handed tinkering, but it was definitely never at a fully playable state on Linux. The remake utterly flies though, so I have hopes that they'll continue development!
