Dynamic Render Distance

Keeps your game smooth by lowering the render distance only when your FPS really drop, then bringing it back up to your own Render Distance as soon as your PC can handle it. No flicker, no world reload, no manual tweaking.

Why DRD

Your setting is never touched. The Render Distance you pick in Video Settings stays as it is. DRD only limits what is drawn, and your own distance is always the maximum.
No flicker. A change never makes the world disappear and reload. Drops slide one chunk at a time.
VSync and FPS limits handled. DRD reads the real cap of your game: your Max Framerate, and your screen refresh rate when VSync is on. With VSync at 60 Hz, 60 FPS is perfect, not “too low”.
No false alarms. DRD pauses when the game itself limits FPS: minimized or unfocused window, loading screens, and the game’s AFK limiter on versions that have one. FPS measured while chunks rebuild after a change are ignored.
No yo-yo. If raising the distance makes FPS fall again, that level is blocked for 5 minutes.
Client-side only. Nothing to install on servers. The server keeps sending chunks up to your own distance, so they are already there when DRD raises it again.

How it works

Every 5 seconds, DRD averages your FPS and compares it to your target.

Target = the lowest of your Target FPS, your Max Framerate, and your screen refresh rate if VSync is on.
Below the target minus the Tolerance: the distance goes down. The further below, the bigger the drop (about 1 chunk per 7% under the target, up to Max Drop).
At 97% of the target or more: the distance goes up by 1 chunk, up to your own Render Distance.
In between: nothing changes.
After each change, DRD waits 10 seconds before measuring again.

Example with the defaults (Target 60 FPS, Tolerance 15%): an average of 48 FPS is 20% under the target, so the distance drops by 3 chunks. Between 51 and 58 FPS, nothing changes. From 58 FPS, it climbs back one chunk at a time.

Settings

All settings are in Options > Video Settings: at the end of the vanilla screen, or on DRD’s own page in Sodium’s video settings. The config button in Mod Menu (Fabric) or in the Mods list (Forge / NeoForge) opens the same screen.

Setting	Default	Range	What it does
Enabled	ON		Turns DRD on or off. Off = your own Render Distance, always.
Target FPS	60	30 – 240	The FPS you want to keep. Lowered automatically to your Max Framerate, or to your refresh rate with VSync.
Tolerance	15%	5 – 30%	How far below the target the average may fall before the distance is lowered.
Min Distance	6	2 – 32	DRD never renders less than this.
Max Drop	8	1 – 8	Most chunks removed at once.
DRD Messages	ON		Shows each change in the action bar (old and new distance, with your FPS).

Advanced settings (only in config/dynamic-render-distance.json): checkIntervalTicks (100 = 5 s), cooldownTicks (200 = 10 s), increaseStep (1). Out-of-range values are corrected automatically.

Updating from an older version

The old settings (Min FPS, Max FPS, Max RD, Decrease Step) are gone. Your config file is rewritten with the new settings on first launch. Your maximum is now simply the Render Distance you choose in Video Settings.

Compatibility

Fabric, Forge and NeoForge, Minecraft 1.18.2 to 26.3 (see the Versions tab for each loader). NeoForge 1.20.1 uses the Forge file.
No required dependency. Optional: Sodium, Mod Menu.
Tested with the vanilla renderer, Sodium, and Iris shaders.
If another mod replaces the world renderer in a way DRD cannot handle safely, DRD stays idle instead of risking a flicker.

Used in the Legends Reborn: Medieval modpack.
