A question abt ps5 performance

Hey guys! I am thinking of getting Assassin Creed Odyssey for my ps5. But I am not sure if i t is gonna run at 60fps since my tv isn’t 4k and is 70hz. Chat gpt says that it will run at 30fps. In the website where I am ant to order the disc it says it is ps5 enhanced and am confused. I want the game to run smoothly not on 30fps. So my question is, is it gonna be stutter and lag. I played GoWR on performance mode cuz the other was stuttery yk.
