Did set my graphics to maximum and reduced “secondary lighting” to minimum (Fair, since can’t disable it) and it improved greatly, didn’t solve, though. So you’re right, something about this addition of “secondary lighting” is sabotaging my hardware. I was wondering about CPU, but it didn’t even reach 50% of its capability, so I doubt it.
It’s so strange that my game runs smoothly in retail (Except in players Hub, but that’s normal. And sometimes some very specific dungeons like Murders Row) than Forever. I’ll report directly through the game and I hope if someone notices then do it as well because it’s quite annoying
