Lost 40- 50% performance across the entire game. EDZ it's also the worst offender for me by far, cosmodrone is also pretty bad. The game doesn't seem any better aside from the new lighting. Running a perfectly stable system that I use for much more demanding tasks than D2. System: RTX 3080 i9 - 9900k OC 5ghz 16 gb ram 3200 mhz 1tb nvme ssd (with good reads and 500 gb left of space) It HAS to be something to do with the game. I always kept track of FPS in this game and other games and it's far worse since the launch of the new DLC. Its staining an otherwise great DLC for me.
