Better optimized than I thought it would be. People with i7 and 970 are having between 40-70 fps. Fraps is completely murdering fps tho (there is an issue with shadowplay).
But bugs, oh boy. Game is literally going to black screen aka crashing every ten minutes or so. It is highly unpolished, many jerky motions, animations, transitions. But they put in new flight system which allows you to go 1000 m/s or more in cruise mode. Same problem still persists, even going 1000 m/s feels like you're standing still unless you have something in front of you like space station.
Space stations are nicely done, look very believable but lack some obvious clues. Game isn't really designed for dumb people in this stage, so many things you need to care about. Have you closed the back hatch or not? Are you in cruise mode, precision mode or combat mode? Where is that bloody quest marker? What I'm supposed to do here where those AI fight each other? Where is my assigned flight pad?
For a game that wants to appeal to mass market this is incredibly complicated, CoD/Halo players won't swallow this. And it isn't really complex at this point, lacking many mechanics. It is just that some things need to be manually done, even though they should be made automatic by flight computer.
