Mac user here. I don't have the GOG version, but am using my original CD copy with a nocd patch applied. I assume what works for my case will be the same for the GOG version. I'm using Wineskin and what works for me is to use the engine "WS9Wine1.4.1NoXInput2". This gives me flawless game play and normal menus. The only problem I do have is if I need to change the key bindings. In that case, I temporarily change the engine to "WS9Wine2.16" just for setting up my controls, then revert back to the other one. Hope this helps.

I'm suffering exactly that fast menus and audio glibberish trouble. Where exactly is that "Limit FPS" option? Is it a Wine or an in-game option?

It is a dxwnd option. DxWnd is a windows program - to be started by wine. You can find it on sourceforge.
Then you create in it a 'target (Edit > add)' enter path to game exe and set options like mentioned 'Limit fps'.

Hope it helps.

Works fine in wine-staging (to be precise, wine-tkg) without any additional tools required.
