ViewDistanceTweaks v1.9-RELEASE

Dynamic view distance and simulation distance adjustment per world — lightweight, fully configurable, and built for performance-critical servers.

Changelog

• Added MSPT variance detection: catches unstable server performance (high tick time fluctuation despite a healthy average MSPT) as its own overload signal — configurable via the new mspt-variance-settings block under reactive-mode-settings.mspt-tracker-settings
• High variance now triggers a virtual overload: lowers view distance by max-decrease-step and can optionally block increases (block-increase-on-high-variance), even while average MSPT looks fine
• Added /vdt simulate [world] — runs the decision logic and shows what would change on the next cycle, without touching any live values
• /vdt status and /vdt mspt now display the current MSPT standard deviation with color-coded indicators
• Added PlaceholderAPI placeholder %viewdistancetweaks_mspt_stddev%
• Internal refactor: decision logic (computePlan) is now fully decoupled from side effects (applyPlan), making /vdt simulate possible and paving the way for more accurate planning in future updates

New Permissions

• viewdistancetweaks.vdt.command.simulate — required for /vdt simulate

Dependencies

• Paper 1.21.x / 26.x — required
• PlaceholderAPI — optional
