PS4 'isn't quite as powerful as Epic was hoping for,' Digital Foundry reports

[HoloDust]

Honestly, lack of full scene dynamic GI (character and moving objects GI is still dynamic, even after replacing SVOGI with Lightmass) is bit of disappointment, but on the other hand, how many PCs currently would be able to run that....if we use Steam statistics, not more than 2-3 percent, if that much.

So, better question might be is SVOGI actually intended to run on anything in near future other than few selected cards that make up for extremely small market share? If PS4 and NextBox can't have it (and it's reasonable to assume that 720 also won't be able to run full dynamic GI), and only few percent of PCs can, for what hardware was Epic actually making UE4 version with SVOGI in the first place?
