fastfastmap

--- # FastFastMap A high-performance minimap mod for Minecraft 1.21.11 (Fabric). Built for speed — parallel chunk scanning, GPU tile caching, and seamless updates with zero flicker. --- ## Features ### HUD Minimap Always-on minimap in the bottom-right corner of your screen. - **Player direction arrow** — red filled triangle with white outline, rotates with your view - **Water bathymetry** — see the terrain beneath the water, depth-shaded in blue - **Smooth height shading** — continuous brightness based on slope, not discrete steps - **Biome tint** — grass, leaves, and water colored per biome ### Fullscreen Map `M` Google Maps-style tile viewer. Open with `M`, close with `M` or `Esc`. - **Zoom to cursor** — scroll wheel zooms centered on your mouse position - **Smooth zoom animation** — no jarring snaps - **LOD tile system** — automatically switches tile resolution as you zoom in/out *(zoom 5 = 16px/block → zoom −3 = 16 blocks/px)* - **Fallback rendering** — lower-res tiles shown while high-res tiles load; no black squares - **Right-click drag** to pan, `R` to re-center on player ### Persistent Cache Your map data is saved to disk and restored on reconnect — no need to re-explore. - Separate cache per **server address** and **world name** - Auto-saves every 60 seconds and on disconnect - Previously explored areas appear on the map instantly when you rejoin --- ## Performance - Chunk scanning runs on **parallel worker threads** (up to 4) - GPU tile cache with **LRU eviction** (128 tiles max) - **Anti-flicker design** — chunk updates never cause blank tiles; old tiles stay visible until the new render is ready, then swap seamlessly. - RAM tile cache capped at **512 tiles (~128 MB)** ## Controls | Key / Input | Action | |---|---| | `M` | Open / close fullscreen map | | Scroll wheel | Zoom in / out (cursor-centered) | | Right-click drag | Pan the map | | `R` | Re-center on player | ## Compatibility Works alongside all major optimization mods. ### Recommended Mods | Mod Name | Modrinth Link | |---------------|---------------| | **Bobby** | (https://modrinth.com/mod/bobby) | | **Sodium** | (https://modrinth.com/mod/sodium) | | **C2ME** | (https://modrinth.com/mod/c2me-fabric)<br>(https://modrinth.com/mod/c2me-neoforge) | | **Lithium** | (https://modrinth.com/mod/lithium) | | **ScalableLux** | (https://modrinth.com/mod/scalablelux) | | **Mod Menu** | (https://modrinth.com/mod/modmenu) | ## Requirements Multi-core CPU RTX 3000 series or higher
