Hey,
ah, that is probably the swap option. That is intentionally disabled as it
conflicts with RSX acceleration that I should also continue to work on.
You can have either RSX graphic acceleration or this swap. It should
theoretically still be possible to support vram swap, say for half of the VRAM
or so. But first I need to understand more RSX details and get them working.
I’m also not sure if vram swap would be stable with the original OtherOS++
direct FIFO use instead of going thru the hypervisor.
There might also the possibility to speed up the ps3 storage driver a bit, so
that using sata ssd as swap could potentially become faster, too. That is
certainly more useful for folks longing for RSC graphic acceleration anyway ;-)
