I have implemented every setting and tweak to totally eliminate stuttering in every car and every track and the game runs smooth as butter except for some online servers where the stuttering is horrible. My FPS stays right at 75 where I have it capped in Nvidia Inspector when the stuttering happens in online server. I can go offline with same car and track and it's smooth as can be. The only thing I can figure is the person that setup the server has "Race Time Scale" enabled and set to something other than none. Having the time scale enabled on my system is the biggest cause of stutter with all cars so I leave it disabled. Am I correct in assuming my stutter issues in some online servers is due to the server admin having Race Time Scale enabled? Other servers with same car track combo are very smooth.
