Using ntfs-3g to run some games (eg Resident evil requiem) causes buffer memory to reach >3 gigabytes compared to just 5kilobytes in kernel ntfs3.
This causes the system (fedora 44) to swap out private memory of several apps just to keep the buffer in memory, for example running a game, 'resident evil requiem' private memory gets swapped heavily while playing on ntfs-3g, priv mem 5.5g -> 3.1g, swap 1.5g). Are ntfs-3g buffers invisible to the kernel that it keeps them in mem and swaps out other apps private memory?
