A partial, curated snapshot of reviewed KytyPS5 Xbox builds, not a full release history. These are editorial summaries of developer notes, not our own performance measurements.

Latest build in this snapshot: 1.1.26301.2318. Checked 2026-10-31. This snapshot covers six reviewed builds and may omit intermediate versions. It does not update automatically; newer releases may exist. A build not marked as a pre-release on GitHub is not proof of stability or game compatibility.
The developer says the Opus audio decoder can now return part of a packet, which some games need to play their sound.
Developer-listed graphics fixes: corrected vertex and instance numbers for some indirect draws, and acceptance of video buffers that use a compression layout the screen previously rejected.
Described by the developer as an experimental Series X|S Developer Mode build that installs over earlier builds and keeps data. A fix does not establish compatibility for every game.
The developer lists one controller list with automatic or manual player assignment, including during a game; a controller with no player chosen plays as Player 1.
Redesigned settings pages, a side-panel game menu with Controllers and Trophies, and a Settings › Display › Stretch to screen option; when it is off, games keep their aspect ratio.
Upstream changes listed by the developer include a memory rework, shader fixes, fewer depth-copy crashes and AudioOut2 audio fixes. The developer says its Remote Controllers option (Settings › Developer) has only been tested by the developer so far.
Brings in upstream rendering work: broader support for clear-colour formats, MSAA resolve handling, and unsupported mesh draws are now skipped rather than halting.
