Batman definitely handled performance much better on consoles than Fallout. No denying that.
Bethesda is not alone in having trouble with performance on these consoles. GTAV remaster had frame rate issues, particularly when driving into large city centers. GTA had patches that made it better, although there was that one infamous patch that downgraded some of the visuals for a few weeks.
EDIT: Either way, Bethesda should have done a much better job at getting shit right this time. It's baffling that they seemingly ignored how infamous they are for technical issues. I don't disagree with that in the slightest.
Still pumped to play this tomorrow, technical issues or not.
