I have two friends playing on a PS3, one seems to be having many issues with freezing and locking up. The other doesn't. My first friend downloaded the 2.1 on release day, the other only downloaded it yesterday... he hasn't played for a few weeks :/ just wonder if it was the initial wave of downloads that had the bug????

As for myself I've been playing on an average spec laptop and i have no issues apart from the obvious lag in densely populated areas
