not to defend them, but I regularly play around 3~4 hours and I didn’t notice my frames dip during play. It usually dip around enter/exit conversation, or when you faster travel, frame then comes back to normal range. (about 120 fps for me, during hotter days I just manually keep it at 60 so I trade some screen tear but cooler room.) If it’s memory leak it will usually lead to crash since you have less and less ram you can allocate. So there might be something that eats your resource.
Mechanical side I just don’t like hunting and gather stuff the scatter around the world, but is kinda of important for early game economics.(especially for a hoarder like me, I want to get all the magical items from vendors, trying to do it as legit as I can, all the sell for 1 coin adds up. opening all the crates etc does took a long time in storage area. )
