Depends on the case. Check this list and try figuring out what was the reason:
- The game uses raytracing(not the RTX) for lighting, so it might not run well on low end videocards. Try lowering the game's resolution/running in windowed mode.
- Avoid using too many light sources and particle sources, like torches an campfires. When you hit around 5, you might start seeing considerable lags.
- Don't go overly enthusiastic with terrain modification. Each modification has a cost.

All good advice.Above!! . is the stuttering recent or always been like that?
