I second btrfs. Even when I was sharing with Windows I used their btrfs driver and it worked fine there too, but I had to occasionally make my user the owner again booting back into cachy, so now I just dont share drives and relegated Windows to a small 120gb SSD for emergency use only.

Remember Polygon was sold to Valnet and is now an AI slop farm so take everything they say with a grain of salt.

Remember when they dropped hardware acceleration a few years ago? That was what got me to move off.
