Well against 6 opponents and 50 planets my PC still runs this game great!
But I did notice some more graphical issues...
1. Disappearing tether/traffic stations happens rarely, even if the game is not a save game, when it is a save game, they all just disappear forever...
2. Ship explosions not happening, tends to happen when their is an excessive amount of firepower, the ship dies and disappears it does not explode.
3. Having 30 Capital Ships together at once is awesome.
4. My goodness there is just way too many terran planets, 50 planets and only 1 ice? Not to mention only one set of rings.
Well guess thats it...
