I have tried literally every fix I've found in any of these threads or posts on the internet about these crashes.

Nothing works. Nothing fixes it. For the love of the big one, please find the cause of these crashes and patch it out! What was a minor inconvenience before is now a gosh darned tragedy if you get a directx crash during primetime gameplay.

And if you can't fix the darn crashes, please reserve someone's spot on the world server for a couple minutes, at least...
