I haven't found many
in multiplayer strate when someone tries to go into relay bunker the game
seems to jam for a bit
i don't use it often so almost missed it, never tried in the antenna.....
i am not the only player who is having this problem a few already reported the same thing
but just didn't report it officially.
This is in the completely wrong place, and there is already a TA5 bug thread in the right place.
Terrain is harder on youre graphics card, satelite view in particular tends to make things drag. You're best bet is to swithc terrain detail to low when entering a relay bunker.
