Intermittent Black Screening

[Romulator]

Amongst the settings you have changed, was turning off SSAO one of them? I would also assume that you have toyed with the Advanced Graphical Post-Effects within the game's options menu, but if you have not, I would recommend unchecking those as well.

You state that you can "predict" when these black screen errors occur based on the area around you. Are you able to state rather specifically where such occur or have occurred?

Also, since you have run the game (and had the black screens appear), did you reopen the game? A new hpl.log file is generated each time the game is run, and as such, overwrites previous logs. I only ask because it appears you only went as far as the menu in your attached log file.
