Hello, does it crash when you launch the .exe file or does it crash when you try to load a saved game?
Could you check if you have some crash log inside AppData\Local\Temp\Gaweb Studio\Glassix 2\Crashes ? if any, could you send them to me on contact@gaweb-studio.com? Otherwise, I'm afraid I can't help much. The game does require some processing power but even with that, it shouldn't crash on startup. Weird.
