I was able to get the jittery graphics to smooth out somewhat by using windwos 8 settings for the game. and it became a lot more playable. the game play problems: only received three elements in three hours of mining (not enough to learn any new tech) every game did this. construction drones kept stopping and not building repairing or removing anything for a long time 30+ minutes or more. moving with the mouse left click was pointless kept sending me into the atmosphere far from the city. I'm not asking for a refund but a fix so its more playable. Its the only game I've puchased through gog that has had issues like this, so I will still buy others but i will be leary about spending more than ten dollars on a game again.
