This is still happening after the big patch yesterday...my buddy teams with me and we do some ground mission and while the combat erupts in the mission I get tossed to desktop with the "Gameclient" error. I log back in quickly, he re-teams and we continue and sure enough not 1 minute later it happens again. Rinse, wash and repeat several times until I just give up and go solo. Hope this gets fixed soon.
i an using a NVidia cards but frankly all the away team missions, teamed or un-teamed, are hopelessly unstable. I get maybe 1 in 3 or 1 in 4 finished without them crashing at least once. Space combat is pretty good, but away team is NOT even close to being ready for prime time
