Gamestudio is working fine under Windows 10. Got a new laptop recently with Win 8 (only worked on 7 before on my desktop), upgraded immediately and I like it so far. Very quick, only some minor annoyances and the touch controls/ touch options and settings are not the best (yet).
@Malice: See my other post in the WIP thread.
