Was having troubles with stuttering and crashing playing modded vintage story in 1.20.3. Followed the steps and the stuttering was almost completely fixed it only happened once after playing for an hour whereas it would happen up to 20 or 30 times within a hour before. The game also didn't crash during that one stutter like it would do sometimes while stuttering. My pc specs are also lower than the main topics but it still didn't kill my pc gpu so I think this is if not a solid fix then it is a good band aid.
