libdeflate VS CompactGUI

zune-inflate is a port of libdeflate to safe Rust.

> The QOI benchmarks shows it only lagging a small bit behind PNG in compression ratio, while performing much faster (multiples) in both encoding and decoding.

Presumably that’s with stock libpng, which uses zlib. I wonder if anyone tried patching it to use the substantially faster (on x86) libdeflate[1] instead? It doesn’t do streaming, but you shouldn’t really need it for PNG textures.

Note that libdeflate has used essentially the same method since 2016 (https://github.com/ebiggers/libdeflate/blob/v0.4/lib/adler32...), though I recently switched it to use a slightly different method (https://github.com/ebiggers/libdeflate/blob/v1.12/lib/x86/ad...) that performs more consistently across different families of x86 CPUs.

Going away from Zlib proper but staying with its format, there’s libdeflate[1], an implementation that’s substantially faster on modern machines but can’t stream, and of course Zopfli[2], a glacially slow compressor that’s somewhat better (and occasionally much more so).

CompactGUI

Also, check out CompactGUI. It's a more user-friendly and efficient way of using Windows' built-in compression to cut the game's file size almost in half. It makes load times marginally longer (like 5-10%) and needs to be redone every few updates to keep the size down, but it works.

You can chuck compact.exe at it by hand (use the /exe option), or if you'd prefer to avoid the command line there's my Compactor tool, or the venerable CompactGUI.

You can also just use compactGui smaller filesizes without having to remove dialogs or cutscenes or anything. Obviously how much space is regained depends on how well it was compressed originally. With triple A titles perhaps getting 10% back, while things like ark can literally be shrunk by hundreds of gigs.

Not really related to your question but if you want to try and save some space you can give this a go, I've used it before and never had any issues. https://github.com/IridiumIO/CompactGUI
