DIRECT ANSWER
What you need to know
Use v1.0.6 for current troubleshooting. Reduced stuttering and improved frame pacing were announced in v1.0.5, not v1.0.6. The newer patch addresses memory stability; it does not promise that every stutter is fixed.
Update and restart
Confirm the installed version and fully restart the game after the update. If abnormal memory or VRAM growth causes instability or crashes, report it through the official v1.0.6 bug-report link.
Separate stutter from low frame rate
Frame pacing and average frame rate are related but different; record when the hitch occurs and whether it follows camera movement, loading or display refresh.
Avoid unsafe promises
The guide does not recommend deleting saves, disabling security features or applying unverified launch flags.
