Has the "some games won't run from XFS" thing been fixed? It was the reason I had to abandon my favourite filesystem on my desktop.

I guess you mean developers not reading readdir spec and being hit with DT_UNKNOWN on XFS? It plagued quite a number of other games.

It's related to this bug: https://bugzilla.kernel.org/show_bug.cgi?id=12688

XFS shows no signs of progress with it.

Another common problem were big XFS partitions (1+ TB) for 32 bit games. It's fixable by adding proper flags to the compiler, i.e. -D_FILE_OFFSET_BITS=64

The workaround for it is known - create a small loop device partition and play the game from there. See example here:
