v1.3.0 Speedy map loading, Indonesian Localisation Update, and Bug Fixes

v1.3.0 Song Loading Overhaul, Indonesian Localisation Update, and Bug Fixes

Mappack Unpacking System (Song Selection Performance Update!)

We've completely re-engineered how MuseSwipr loads songs! This is a behind-the-scenes/technical overhaul that should make the song selection experience much smoother.

  • For returning players - when maps are loaded for the first time, the game will "upack" the mappack so that in the future, scrolling past it and selecting/loading it will be much faster (it'll basically generate a thumbnail and a 30s audio preview, as well as gameplay data).

  • Bulk migration - Press Ctrl+Shift+U in song selection to migrate all your existing maps to the new format at once (optional, but recommended for best performance! Otherwise, mappacks will slowly be migrated as you play/click on them in song select). Depending on your library size and computer, this may take awhile! As a rough estimate, ~300 maps took 7 minutes.

  • Note: Bulk migration only works with "V2" maps. Older V1 maps will be unpacked as you click/play on them due to technical issues.

Other Improvements

  • Per-difficulty images - Maps with different images per difficulty now show the correct image for each difficulty in song select (once unpacked)

  • Prepping for the future - This is a huuuge (technical) step towards making the song select experience better and the eventual song select overhaul we want to do in the future.

Steam Workshop Importing Improvements

  • Consolidated progress panel - Improved the bulk importing experience of Steam workshop items. No more spam of notifications (and way less FPS drops)! Instead, it'll show in a nice lil progress panel.

  • Checkpoint saves - Importing progress is now saved periodically, so if the game crashes, or you quit mid-import, you won't lose progress on the imported maps when you next launch the game.

Bug Fixes

  • Importing new maps from the Steam workshop should properly update the difficulty visually without needing to click on it first

Localisation Updates

  • Updated the Indonesian localisation - massive thanks to handofmyths for updating it!

Known Issues

  • Some maps (mainly v1 maps) may not show the correct difficulty when loaded.

  • Difficulty of v1 maps does not update with speed changes.

  • Sometimes importing Steam maps might randomly fail. You can retry these by pressing "F5" or unsubscribing from the Steam workshop item, and then resubscribing (and maybe pressing F5/restarting the game). If it still does not work, you can verify the integrity of MuseSwipr's files through Steam.

What We're Working on Next

  • More new built-in songs an new mechanics!

  • Song select showing collapsed mappacks instead of every map within it at once

  • DX12 support (no promises, but we're trying!) - DX12 can help with performance but can have unexpected behaviour. If you want to try it yourself, use -force-d3d12 -screen-fullscreen 1 in Steams launch options. Huge thanks to Veii for testing with DX12 on MuseSwipr.

  • Many more things!
