Need for speed Unbound stuttering on PS five

My game stutter is really bad at the end of a police pursuit if I’m going too fast through it speed trap end of a race getting collectibles doing challenges I’ve tried to do everything I can on my system and I just don’t think it’s my system. I honestly believe that it’s server sided lag. Because nothing I did fixed the stuttering and I genuinely don’t wanna play the game because of it ruins the entire experience I crash and lose races way too frequently because the game stutters and I just honestly don’t know what to do.  And also, I feel like the graphics are set way too high for a console my brand new PS5 is struggling to run the game. I don’t know why you would put the game on ultra graphics for a console I like the graphics but I would rather have worse graphics and actually be able to run the game properly because I don’t know if it’s the graphics or server sided lag, but the stuttering is absolutely horrible and sometimes my game will just freeze completely
