Yeah might be a good point. I also think a lot of people try to play 1 vs 1 ranked instead of custom games because 1 vs 1 is a smaller scale game. Even if the map is bigger, the max number of units is capped at 500, so there won't be those wicked lags I see on 2vs2 or 3vs3 games with players with slightly weaker computers.
I really think that's the holdup for SupCom becoming really huge. It just demands SO MUCH from all the computers involved. I wish there was a way to put it in a "lite" mode where the graphics were simplified even more to try to help speed up the game.
Oh well.
