Not sure if this will help as I just purchased the remake today on sale, and had really bad stuttering. The fix was one I remember using for Control and other DX12 titles.
Add the game .exe into "exploit protection" within Windows and then tick the override for Control Flow Guard (CFG) and toggle the slider off. Reboot. And then also for good measure I deleted the contents of C:\Users\<Username>\Documents\Dead Space (2023)\cache. Fired up the game and stutters have gone.
Hope this helps.
