Hi!
I'm playing on lower end computer (although above min spec) and because of this expirience some performance issues which might not be reported previously. First of all it's not easy to force the game to use SLI graphics. Beside this - generally combat runs pretty smooth for me (at least on simple graphics setting, have to re-check on higher [edit: just checked on "good" - animation is still smooth when no ship is selected, otherwise is crappy]), but when i select and highlight any ship it starts to drop fps significantly. Once I unselec ship it goes smooth again.
Other UI issue - on lower resolutions bottom bar (with ship parts) is to wide and covers bottom part of ship stats dialog. It's impossible to read funel efficiency, even after scolling dialog down to bottom.
anyway - great job, this alpha tutorial feels nearly like full game can't wait for campaign.
cheers
Piotr
