The performance of Dragon's Dogma 2 can be summarised with one utterance: CPU. It doesn't really matter whether you're measuring performance in the city or the open world, the processor and platform you have will play a huge role in determining whether or not your graphics card has a chance to shine in this game.
If you have a mid-range or budget-level gaming PC, you're unlikely to see performance figures in excess of 60 fps in the open world areas. In the main city, though, you'll be looking to hit half that figure, even at 1080p with low quality settings.
Only with a modern CPU and graphics card will you stand any chance of having a smooth gaming experience. Capcom's recommended hardware requirements should really be viewed as the absolute minimum, and ideally you're going to need a 12th Gen Intel Core or
Ryzen 5000-series or better CPU. You can get away with just having six cores, as long as the chip supports multithreading. At least it's not especially demanding on the system RAM.
Hopefully, most of the frame rate issues I saw will be solved with future game patches and driver updates. But there's clearly a lot of work to be done in optimising everything further.
