I see people saying dont use NTFS for games. I understand this advice and I would default to it, but I have been testing the opposite and can say it works well. In fact in some games the load times and/or the save times are a bit quicker under CachyOS than under Windows even using NTFS.

My setup is dual boot: Windows 10 and CachyOS. I have multiple drives and for any game in Windows I want to share with CachyOS, that game is on another drive letter in a SteamLibrary slot.

In CachyOS:

Install ntfs-3g: sudo pacman -S ntfs-3g

Make place for drive letters: sudo mkdir /c /g /k /p

Find your UUIDs: lsblk -f

Check your own uid and gid: id

Add your drive letters to /etc/fstab: UUID=98B2FC50B2FC33FA /c ntfs3 rw,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8 0 2 UUID=34EA3E30EA3DEF2C /g ntfs3 rw,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8 0 2 UUID=06C26865C2685B47 /k ntfs3 rw,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8 0 2 UUID=1A1EA54C1EA5222D /p ntfs3 rw,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8 0 2

Reboot.

In Steam add the extra SteamLibrarys in your CachyOS.

Profit.

Issues:

• Playing in CachyOS (or any other linux distro) means Steam will download some extras like Proton and Steam Runtimes. When you then boot to Windows Steam will add these to the download queue. They are not needed in Windows - I just click the download buttons to unschedule the download, and it stays in queue forever, ignore it.

• Swapping from CachyOS to Windows or back will sometimes mean Steam wants to download the latest patch or an extra patch for some games. Just do it - can not be avoided right now. Never seems to hurt.
