Correct me if Im wrong but dont they limit frametimes so they can reduce tv stuttering? NTSC standard for TVs is 29.94 or 59.94 fps. I assume they chose the 30fps so it can be used more widely and if its scaled to 60 it would just increase frametime lag. Again, im not sure.
Also, comparing CE2 to CE1 is like comparing UE5 to UE4. Also, i dont remember but doesnt starfield use the havok engine for animations?
Edit: rather than downvote just tell me where I am wrong
