Hi, I have a modest PC : intel 3ghz, 1024 DDR, 6600GT nvidia. On my PC, the galactic map of 194 planet have little lag at start but after 10 or 15 day, the game become very laggy But some of french player use this map without laggy ( they have probably a very good Pc ). With my config, 90 planet is the maximum for optimal game, after , I have some laggy day after day I play. My dream, a hudge galactic map of 400 or 500 planet but the limit is 195 planet, after this limit, the game crash and too much lag are present.
