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. ## OS Compatibility | OS | Compatible | | ---------------- | :--------: | | Windows | ✅ | | MacOS (ARM) | ✅ | _Tested on Apple M1.
