Space Marine 2 DLSS 4: Multi frame gen bad?

Hi everyone

I just got a new NVIDIA 50s GPU, and I would like to know your experience using Multi-frame Generation on Space Marine 2 specifically to decide whether I should turn it on or not

I heard a lot about input lag but is it noticeably worse compare to not having it on? Is there any story where you guys fail mission because of it? Does it happens often? Is there any noticeable visual artifacts or anything game breaking?

Thank you for your attention to this matter!
