Straight from GPG the games pathing has been overhauled in SupCom2. This was a big part of the issues with the AI units that was causing lag because of pathing. Among other issues to that’s been fixed and optimized. So rest assured the game will play much better.
They said much the same thing about the expansion, and did things get better? No, they got a lot fucking worse.
I can't play any long game with AIs in it without the sim speed dropping to -10. Since I either play alone with AIs or with a mate with AIs, that's a game breaker for me.
It would take something like a change of management over there at GPG for a problem of this nature to actually get fixed, because the old management definitely did not give a rats arse.
