So, uh...this game may not be anyway near as clear-cut a "win" for a given platform as I first though. People are pulling up screenshots now where PS5 has much worst lighting in some areas as well as lower environmental detail/objects and worst cloth physics compared to the PC and Series X versions.
If that's the case, it's not surprising if PS5 has less framerate drops (and according to DF, it DOES have frame drops, just not as much) due to the aforementioned differences. Some of the screenshots almost look worlds apart IMO. Hate to pull it from Reeee, but here 'ya go:
