I have no specific answer at the moment, but I always test everything I make with my decade-old laptop (just kept it for this testing purpose), which is an i3-3310m with an Nvidia GeForce 610m 1GB. I have a stable 60-70 fps with dynamic shadows turned off.
Two of my testers have an average PC, and they had no problem on the highest available settings, they had the constant 100FPS. (i5-6500 & GTX 1050ti) (i3-9100f & GTX 1650)
