How do I install Asynchronous Reprojection?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does Asynchronous Reprojection work with?

The listing gives Minecraft 1.20, 1.20.1. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This mod (especially in its current state) is more of a proof of concept than actual optimization mod!

It has many issues and greatly reduces performance of main rendering thread (even when disabled), so for comparing performance use instance without mod installed.

About

Asynchronous Reprojection creates second rendering context to asynchronously reproject frames from main rendering thread with new camera rotation and player position.

It was inspired by Comrade Stinger's demo, which was also base for shader code: https://www.youtube.com/watch?v=VvFyOFacljg

Known issues:

Fabric version works only on Windows and Linux (I haven't tested it on macos). Forge version works only on Windows.
Screenshots (F2) and world icons don't work - they're black.
Minor visual glitches.
Camera bobbing is disabled.
"Fabulous" graphics doesn't change anything compared to "Fancy".
Camera sometimes rotates itself when opening or closing GUI.
Forge version crashes when trying to resize window during startup.
It sometimes just crashes (for no particular reason).
