If both threads properly lock/unlock then you should be ok. But creating a shared context will remove the need to lock at all (at the cost of an extra context). > 2.

It might even be a non-trivial performance win for some drivers, because you'll skip running through their allocators. -- Christopher Wright christopher_wri...@apple.com
