Taking a screenshot can freeze the game for a noticeable moment. This mod moves the heavy work — PNG encoding and writing the file to disk — off the render thread, so pressing F2 no longer causes a frame hitch.
Client-side only. Works on Fabric, Forge, and NeoForge. No config needed.
When you press the screenshot key, vanilla Minecraft encodes the image to PNG and writes it to disk right on the render thread. That freezes the frame for tens of milliseconds. Taking screenshots in quick succession — burst capture, recording, or just mashing F2 — makes it worse, especially at high resolutions or with large resource packs.
The render thread grabs the pixels from the GPU (that part has to stay there), then hands everything else off to a background thread: generating a unique filename, encoding the PNG, and writing the file. A semaphore makes sure concurrent screenshots don't collide on the same filename. When the write finishes, the "Saved screenshot" message is delivered back on the main thread, just like vanilla.
If the mod can't hook into your game version, it disables itself and screenshots behave exactly like vanilla.
mods folder.Classic Forge users: you also need MixinBooter installed, since classic Forge doesn't ship with a Mixin loader.
Requires Java 17 or later.
Tested on Minecraft 1.18 through 26.2 across Fabric, Forge, and NeoForge. If the mod can't hook into your specific version, it disables itself quietly — the game runs as if the mod weren't there.
