--- Comment #25 from Alexandre Demers alexandre.f.demers@gmail.com 2012-09-06 17:19:09 UTC --- I'll have to confirm it later today by disabling VM, but I'm pretty sure I experienced a lock (can be reproduced every time) related to VM when testing with Unigine Tropics. It loaded, the demo began and then it locked when the island appeared at the horizon (I guess that's what it is since it was the first time I was running this demo).

From the retrieved logs, I could only identify a GPU lock with a reset that

failed to reset rings properly.
