can someone knowledgeable give more insight about the flexible memory?
Sony said
""Flexible Memory" is memory managed by the PS4 OS on the game's behalf, and allows games to use some very nice FreeBSD virtual memory functionality. However this memory is 100 per cent the game's memory, and is never used by the OS, and as it is the game's memory it should be easy for every developer to use it."
what's FreeBSD virtual memory functionality? advantages, disadvantages, why have it be flexible at all etc. this is the first time I heard about 'flexible memory'
