Where it stands

Two Minecraft builds are covered here: Minecraft Preview (PPSA19639) and the main game (PPSA17221). Both have been run on Windows. Minecraft Preview has the clearest report. On a locally patched build it reaches the title screen at 60 fps, creates and loads a world, walks around, and saves and quits. Saves show up in the world list afterwards. Keyboard input and audio work.

Speed is the weak point. At the game's default render distance (36 chunks) it draws 2,000 to 4,000 times per frame. On plain main that is about 7 fps. The reporter's speed-up patch brings it to about 31 fps. Lower render distances reach the 60 fps cap. In the screenshot of the world the game's own counter shows 21.6 fps.

A lot of fixes were needed. The Preview report lists eleven stops on main, including network calls that must fail late instead of at once, missing sign-in and sound libraries, a game thread that waits forever for a graphics event the console always sends (an end-of-pipe interrupt), and fake storage numbers that triggered out-of-storage dialogs. The reporter's patch includes stubs and is not ready to merge as it stands. A separate opt-in PR for the graphics event fix was closed.

For the retail game (PPSA17221), a different contributor (kjhq) says that main plus a set of their PRs plus some local changes loads a world on Windows. Most of that set is now merged on main: socket address handling, network read and write events, a Windows file-sync fix, mprotect, a write-throttling query and IPv6 address data. The game also needs a separate PR (#716) to load modules in its app root.

What is stopping it

• Performance: thousands of nearly identical draws per frame are handled by a single worker thread. The reporter's draw-run speed-up is not upstream yet. Thread
• The game waits forever for an end-of-pipe interrupt that its own graphics streams never request. The real console always sends one. An opt-in fix PR was closed by the project's intake pause. Thread
• Several fixes in the reporter's patch are stubs and are not ready to merge, including sign-in, text-to-speech and save-data search behaviour. Thread
• The retail game needs PR #716 to load the modules in its app root. Thread

How it got here

1. 7 Oct 2026Retail Minecraft (PPSA17221): a set of network and kernel PRs is opened. With them, plus local changes, the game loads a world on Windows. Source
2. 7 Oct 2026Minecraft Preview bring-up report: title screen at 60 fps, world creation, loading, walking and Save & Quit all work on a locally patched build. Source
3. 8 Oct 2026Merged: guest socket addresses are accepted whatever their length byte, which fixed every failed bind in the game's networking. Source
4. 8 Oct 2026Merged: Windows file sync no longer needs administrator rights, and async HTTP requests now report failure as a completion. Source
5. 8 Oct 2026Merged: POSIX mprotect, a write-throttling query, IPv6 address data, and a thread stack size below 16 KiB now returns an error instead of crashing. Source
6. 10 Oct 2026A PR for the missing end-of-pipe graphics event was proposed as an opt-in fix, then closed. Source
7. 11 Oct 2026Merged: read and write events for guest sockets, a long-standing piece of work the game needed. Source
