Haven't gotten further than just before the intellect devourer fight in the nautilloid wreckage because my framerate drops like a rock and I get extreme amounts of stuttering. It's unplayable.
Nothing I've done fixes it.
I'm running on Ultra with a RTX 2060 and had absolutely 0 issues before thus patch.
I've had similar issues with a 1660Ti. Frame rate will suddenly drop through the floor for no apparent reason. Not an issue I ever had prior to the patch. Also saw many instances of graphical corruption when things did work ok. Something is very wrong with Vulcan. Had to switch to the DX side to make it playable.
DX has been and continues to run smoothly for me. Dunno what they broke in Vulcan but something got glitched. I never had stutter issues before the patch.
I swapped to Direct X and ended up with absurd load times once in game. Like, the game finished loading, then I had to wait 2 minutes for the terrain to load in.
Felt like my old days of playing Asheron's Call 2 with dialup internet.
Their early system requirements is well below this. Though I'm afraid of it's 150 GB size request. That's just insane. Guess they're trying to beat out CoD:MW(200 gigs).
