So far I've only encountered this on Tattooine, and it seems to only happen in the Dune Sea region. I started travelling into the dunes and the game just crashed to the desktop with no error. Loaded the game back up, loaded the character, and after about 30-45 seconds, same result. 5 more tries, same thing. Drivers are up to date and I've run the repair on the launcher, but it hasn't seemed to help.
