| Feature | Official 4.04 | Unofficial 404b | |--------|--------------|----------------| | Stability | High | Mixed – crashes reported in Toussaint | | Performance | Solid 30 FPS | Unstable 60 FPS (requires OC) | | Cross-save | Works | Often broken | | Mod compatibility | None | Light mods (visual tweaks) | | Risk level | None | High (ban potential) |
