Updating the Modpack & Tags
Before a new Ultralight update gets uploaded, it undergoes simulated gameplay testing to assess performance under normal conditions. If the update meets our internal performance targets, it will be released with an “A” in the version name. If it fails to meet those targets, it will be released with an “F” in the version name.
Tags
- A — Stable and user-ready; no major issues.
- B — Acceptable but below optimal performance targets (FPS and/or frametime slightly off).
- F — Performance issues; FPS and/or frametime significantly below target.
