I'm really enjoying sailing the seas again on this beta. I have been having difficulties with the beta crashing. Any helpful tips are greatly appreciated.
Making these adjustments to your options should help reduce your crashing.
Turn On Vsync
Set Graphics to Custom, then make all the settings Low or Off.
Leave Fancy Loading Screen on, this keeps you from crashing when you're loading zones.
If you're still crashing a lot, turn off the game audio in options.
