Do deduplicating filesystems do bit-level deduplication? Wouldn't change unoptimized media, but still curious, what the difference would be.

ZFS will do block level deduplication but requires a large table be stored in ram. The issue arises that the cost to increase your ram to keep up with that table size usually ends up being a lot more than just adding more storage.

I do believe most games have an inflated size due to uncompressed assets being included which a file system level compression could help with so long as you have the CPU to spare.

Thanks for the explanation!

Btrfs can do that, but the CPU load would be uncomfortable.
