When somebody says "isnt playable" I imagine something like 0-5 FPs
10-15 is hard and 15+ is just good.
Actually game is just bad made. Void Star is almost unplayable on wine/windows. Last Denova WZ is just going 30FPs around, but has more details like grass.
But that post was about initial loading. It takes 5 mins to load...also game has option to start single core mode. Will try to force it for tests
edit: it's not 2 cores, it is fork(). should be single process or 2 of them. Will try tomm some fights into single one.
