Visceraquite playable at 30 - 40 fps in normal space.
Same here. Maybe it's personal, but even 30-40 fps are making me dizzy. I need none less than 50, 60+ at best. Rare occasion of game actually making me feel physically bad because of poor performance. Many games that run at same '30-40' fps I just find jerky and uncomfortable, but this... Something strange. Can't play it more than 20-30 minutes.
