BenchmarksHorizon against Java Edition 26.3

-

Same machine, same world, same flight.

-

We run Horizon and vanilla Minecraft: Java Edition 26.3 one after the other on the same computer: a fresh world from the same seed, the same settings, and the same four flights over a village, a forest, the ocean and a mountain. Every figure comes from the same code for both games. Where Java does better, the tables say so.

- -
-

Measured by us

-

The project's own machines, at render distance 12 (vanilla's default) and 32. VSync off, no frame cap, a 1280x720 window, simulation distance 12, everything else at vanilla's defaults. Each figure is the median over the runs; the frame figures are averaged over the four flights.

Your hardware

-

Pick a graphics card, a processor and, if you know it, your memory. If we or at least three players have measured that pair, you see what was measured; otherwise an estimate from the nearest measured machine, as a range.

Render distance - - -

The picker needs JavaScript; the tables above and the method below work without it.

-

From players

-

Players who allow benchmark uploads in the launcher's data collection settings share the report of horizon-client --benchmark standard. Results are grouped by graphics card, processor and render distance, and a group shows only once at least 3 different installs are in it, so no one can be picked out. Only medians are published, with how the group's installs split by memory, graphics memory, drive and system in coarse classes (each class only with at least 3 installs too): no install ID, date, driver, exact memory or screen.

How the estimates work

-
-

An estimate starts from the measured machine closest to the one you picked, then scales its figures with a small table of specifications we wrote ourselves (no benchmark database):

-
    -
  • GPU factor: the geometric mean of the two graphics cards' ratio of FP32 shader throughput (TFLOPS) and of memory bandwidth (GB/s), as their makers state them.
    • -
  • CPU factor: the ratio of the two processors' single-thread scores: top boost clock times a rough factor per chip generation (Zen 4 = 1).
    • -
  • Frame rate: when the measured run split each frame into CPU and GPU time, the slower side is scaled by its factor; otherwise by the geometric mean of both. Whatever the split, the real figure lies between the measured one scaled by the smaller and by the larger factor; we widen that by 15% for the roughness of the table, and show it as the range.
    • -
  • Load times are CPU work (generating, lighting and meshing chunks), scaled by the CPU factor. Memory is not scaled: it follows the world and the settings, not the speed.
    • -
  • Memory size: when players' results say how much memory and graphics memory their machines have, a measured group whose players have neither yours counts as further away, and the estimate says what they had. With your memory picked, it also says when the game's peak use is a large share of it.
    • -
-

Estimates ignore drivers, the graphics API, thermal limits and the operating system, which can matter as much as the chip. Treat them as a rough idea, and run horizon-client --benchmark standard on your own machine for the real figure.

How we measure

-
-

tools/perf_bench.py starts each game from a fresh world (seed 1234, creative), waits until every chunk around the spawn is loaded and drawn, then for each scene teleports, waits for the chunks, holds for 2 seconds and flies a straight 192-block path in 12 seconds. Every frame is recorded. Vanilla runs as players get it (your own client, the official launcher's Java options, Java 25), driven by a small development-only mod that only calls the game's own code; nothing of Minecraft is shipped. The full method and its caveats are in docs/benchmark.md, and every raw report is in the repository.

-

Measure your own computer with horizon-client --benchmark standard --render-distance 12: it writes a report to the benchmarks folder of the game folder.

    Where Horizon is going

    -

    What is being done, what comes next, what shipped and where you can help. No dates: things are Now, Next or Later. Read it in plain words, or switch to the technical picture.

    The roadmap lives in the repository: ROADMAP.md, generated from roadmap/roadmap.toml. Pull requests carry the roadmap:<id> label of their item.

    -
    - -
    -
    -

    Every open issue and pull request, placed by its state on GitHub, as on Kira's work board in Discord.

    - -
    -

    Every release with what it changed, grouped by roadmap item in Technical, and a summary of each week. Also as journal.json.

    Good first tasks

    -

    Each one is a small difference from vanilla, with an issue that says how to see it.

    -

    Each links its issue; the technical text says where in the code and in vanilla to start.

    Ways to help

    -
    -
    -

    Tell us what differs

    -

    Something that doesn't play like vanilla is a bug. Say what you did, what happened and what vanilla does, with your Horizon version and system.

    -

    Report a bugSuggest something

    -
    -
    -

    Take a task

    -

    Pick a good first task or an open issue. On Discord, /claim 1234 tells everyone you are on issue 1234, so nobody starts the same work; /unclaim frees it.

    -

    Open issues

    -
    -
    -

    Bring your AI agent

    -

    On Discord, /agent connect gives your coding agent a personal token for Kira's MCP server: it reads the work board, claims tasks and posts its progress in your name.

    -

    Join the Discord

    -
    -
    -

    Benchmark your computer

    -

    Run the built-in benchmark and share the report: every new machine makes the performance work more accurate. No coding needed.

    -

    How to

    -
    -
    -
    -
    -

    Report a bug

    -

    One bug per report: something that breaks, or doesn't play like vanilla. It becomes an issue on GitHub, public, and you get its link to follow it. Search the open bugs first.

    - -

    Report it on GitHub or in #horizon-bugs on Discord, where Kira turns your post into an issue.

    -
    -
    -

    Suggest something

    -

    An idea for Horizon, or about something on the roadmap. The maintainers read every one, and the good ones become roadmap items. Nothing you send here is published.

    - -

    Post it in #horizon-ideas on Discord, or send it to Kira with /suggest.

    -
    -
    -

    The rules

    -
      -
    1. Vanilla is the specification. Wherever Minecraft 26.3 has the feature, Horizon does exactly what it does: read vanilla's code, then match it.
      2. -
    2. Small pull requests, proven. One change each, under about 500 lines, with the block python3 tools/pr_ready.py prints: formatting, Clippy, tests and the harnesses your change can affect.
      3. -
    3. Say who wrote it. If an AI agent wrote or posts it, the pull request says so, and commits keep its co-author line.
      4. -
    4. Never commit Mojang's files. No game jars, assets, decompiled code or prepared resources, and nothing taken from other mods' code.
      5. -

    Minecraft: Java Edition 26.3Rust

    -

    Horizon: The game you know, rebuilt in Rust.

    -

    The Minecraft: Java Edition 26.3 client and its game logic, rewritten in Rust and checked against the vanilla game by {{HARNESSES}} differential harnesses.

    -
    - Download the launcher - View on GitHub -

    01What it is

    -

    Horizon rebuilds Minecraft: Java Edition 26.3 in Rust, one subsystem at a time, and holds every piece to the same inputs as the vanilla game until the outputs are identical.

    -
    -
    - -

    Your own copy

    -

    Install Java Edition with the official launcher and play 26.3 once. Horizon builds its resources from those files on your machine, and never downloads or shares game files.

    -
    -
    - -

    Native on three platforms

    -

    Linux, macOS on Apple Silicon and Windows. Worlds come from a Rust port of the vanilla generators, drawn with vanilla's block models, lighting, sky and fog.

    -
    -
    - -

    Open source

    -

    Horizon's code is MIT. It contains no Minecraft code, assets or data; those belong to Mojang and Microsoft under the Minecraft EULA.

    Captured in the Rust client itself, with vanilla assets from the player's own copy and no mods or shaders.

    04The launcher

    -

    One small app, then play

    -

    The launcher installs Horizon, prepares it from your copy of the game and keeps both up to date.

    -
      -

    • One-click install

      Pick a release and it installs the build for your platform into its own folder, then prepares the resources from your Java Edition 26.3 install.

      • -

    • Updates on its own

      It looks for a new Horizon release when it starts and every four hours, and updates itself from the launcher's own releases.

      • -

    • Client or server

      Start the client, or host a server from the Servers page: create it, start it, watch players and the console, change its settings and keep backups.

      • -

    • Logs and crash reports

      The Settings page shows where the game's logs and crash reports are, and horizon-launcher logs prints them.

      • -

    • Modpacks and packs

      The Modpacks page reads a Modrinth or CurseForge pack and carries over the mods Horizon can run. The Mods page installs resource packs and modpacks from Modrinth.

    Privacy: this site sets no cookies, has no analytics or trackers and loads nothing from third parties except GitHub. To show the latest releases, patch notes, links and contributors, your browser asks api.github.com and raw.githubusercontent.com for them, and avatars.githubusercontent.com for the contributors' pictures; GitHub's privacy statement covers those requests. The launcher sends nothing unless you allow it: what it can send, and how to delete it.

    PrivacyData collection

    -

    Nothing leaves without your yes.

    -

    The Horizon launcher can send a few things that help make the game faster and steadier. It asks first, each kind has its own switch, and every switch is off until you turn it on.

    -
    -

    What can be sent

    -

    Only the kinds you allow, from the launcher's first-run question or Settings → Data collection:

    -
      -
    • Performance statistics, after each play session of a minute or more. These are the frame-time and tick-time percentiles and a 14-bucket histogram (never a recording of each frame), the peak memory, how long the game took to start and to load the world, and the settings that change performance (render and simulation distance, frame limit, VSync, fullscreen, graphics mode).
      • -
    • Crash reports, when the game crashes. They hold the error, where it happened in Horizon's code, your graphics adapter and settings. They hold no log, no world, no server and no resource packs.
      • -
    • Bug reports that you write and send yourself. The end of the game's log goes with one only if you add it after reading it, and lines of chat are removed first.
      • -
    • Benchmark uploads of the benchmarks you run. They are shown publicly on the Benchmarks page, only as medians of groups of at least 3 different installs with the same graphics card, processor and render distance; never one by one, and never with your install ID, the day, your OS version, driver, exact memory or screen.
      • -
    -

    Each one also carries the Horizon version, the day it was made (not the time), and a description of your machine, because that is what explains how fast the game runs on it:

    -
      -
    • the operating system, its version and the processor architecture;
      • -
    • the processor model, its cores and threads, and its base and boost clock where the system gives them;
      • -
    • the memory, rounded to the gigabyte;
      • -
    • the graphics card the game draws with: its model, maker, whether it is built into the processor or separate, its own memory, its driver version and the graphics interface (Vulkan, Metal, DirectX 12);
      • -
    • the kind of drive the game folder is on (NVMe, SSD or hard disk);
      • -
    • the screen the game opened on: its size in pixels, refresh rate and scaling;
      • -
    • whether the computer is a laptop or a desktop, and whether it runs on battery.
      • -
    -

    No serial number, computer name, user name, network address or file path is read. Each item also carries a random install ID. The launcher makes that ID the first time you allow something; it says nothing about you and exists only so that your data can be deleted.

    -

    Never sent: your Microsoft or Minecraft account name or UUID, world names, server or LAN addresses, chat, and your user name or home folder in file paths. Before anything is kept, those are replaced with placeholders, along with e-mail and IP addresses. The server does not store the IP address requests come from.

    -

    The launcher shows exactly what would be sent: Settings → Data collection → View what would be sent, or horizon-launcher data show. Every field is listed in docs/telemetry.md.

    - -

    The "I'm playing" ping

    -

    The game sends an anonymous "I'm playing" ping, so the launcher can show how many people play Horizon right now. It is sent once a minute while you play, whatever the switches say.

    -

    It holds: a random number made when the game starts and forgotten when it closes, the Horizon version, your operating system (Linux, macOS or Windows), and whether you have a world open to LAN or to friends. It does not hold: your account, your install ID, world or server names, your hardware or settings, or anything you do in the game. The random number changes every time you start the game, so two of your sessions can't be linked to each other or to you.

    -

    The server keeps the pings in memory only, never on disk, and not with the address they came from (that is used only to stop abuse, as below). A session counts while it pinged in the last two minutes and is then forgotten. What it shows is the number playing now, per version and with a world open, rounded.

    -

    To find what is slow or crashes on which machines, and fix it. The ping shows players, and Horizon, how many people play right now. Benchmark uploads also show other players how Horizon runs on hardware like theirs. Nothing is sold, shared for advertising, or used to identify you.

    - -

    On what basis

    -

    For the switches: your consent (Article 6(1)(a) of the EU's General Data Protection Regulation). It is given kind by kind, recorded on your computer with the version of the question you answered and when, and withdrawn at any time with the same switches. Withdrawing deletes what was waiting to be sent. When what is collected changes, the launcher asks again, and nothing new is sent until you answer. The ping holds nothing that identifies you; the address it comes from is used only to limit how often one address may send, kept in memory for an hour at most and never stored.

    - -

    Where and how long

    -

    Items wait on your computer (telemetry/ in the game folder) and are sent compressed when the launcher starts or closes, to Horizon's own server, telemetry.playhorizon.dev, hosted by Railway in the European Union (Amsterdam, the Netherlands). The server keeps them for 180 days, then deletes them. What stays after that are anonymous totals per day, Horizon version, operating system, GPU maker and render distance (for example "120 sessions on macOS with Apple GPUs at render distance 12"). They hold no install ID, and groups too small to be anonymous are never shown. Published results also show how players split by memory size (in steps: 8, 16, 32 GB…), graphics memory, drive type, operating system and built-in or separate graphics, each class only once it holds at least 3 different installs; the exact values, the driver, the clocks and the screen are never published.

    - -

    Deleting your data

    -

    Settings → Data collection → Delete my data, or horizon-launcher data delete. The server deletes everything sent under your install ID, your share of the totals is recomputed, anything waiting on your computer is removed, and you get a new install ID. You can also turn everything off, or delete the telemetry/ folder.

    - -

    Your rights and contact

    -

    Horizon is made by Ludovic Marie, who is responsible for this data. To ask for a copy of what was sent under your install ID, have it corrected or deleted, or ask anything about it, write through lu4ovic.com (give your install ID, shown in Settings → Data collection). You can also complain to the data protection authority where you live.

    ReleasesEvery version, newest first

    -

    What's new in Horizon

    -

    Each release lists what it adds and fixes, then its full notes and its downloads. New versions come out many times a day as changes land, and the launcher installs each one once it has passed its test. The launcher has its own releases.
