@JMC47 - Why ask me though? Go poke neobrain or degasus :p
When I was trying to get a detailed explanation of Real vs. Virtual XFB, I gathered they were two different approaches to XFB emulation (roughly comparable to EFB2TEX vs. EFB2RAM). It could very well be that current XFB emulation sucks and an improved model could fix it so that only Virtual is needed. Or one approach could continue to do things the other can't. Again, you're not asking the right person.
