By the way, I get the same error with GDB as everyone else.
And It's not a shadercache issue. I've just install the game under 0.5.6 and it worked like a charm. A little "buggy" at first, but not a lot. With 0.5.7, it keep jammin and it never recover, well I've never waited more than 10 minutes... but I don't think it's a cache problem if I have to wait 10 minutes.
