When ever I launch DOTA2 I have to reset the region, however I didn't have to do this on my laptop?
Any ideas what maybe causing this?
(I don't use any autoexec options)
Yeah, same thing happened to me, but I wouldn't think much of it, as it's in closed beta still and isn't perfect yet. I have notified Valve, and they will probably get on that soon, because closed beta is just that- people playing the game, detecting problems, and reporting then to the devs to fix. All in all, there's no fix that us users can implement, but Valve is good about stuff like that, so keep up with their response. (if any)
