Since last upgrade my game has crashed completely.
Crashes the computer also , and needs complete re-start.
Just tried game again.
crash only happens when game on full screen.
Could you get it to crash again, then upload the logfile?
You can find it in SteamApplications/GearCity/GearCity/ the name of the file is logfile.log, you can upload it directly here.
Give it a go when I get home
