If I remember correctly from the Nvidia presentation, it was about GPU loading compressed game data from SSD and extracting then inside GPU using GPU cores to reduce latency and load on CPU.Yep, Direct Storage is only coming out mid 2021 and then after that developers have to implement it. I don't know what the heck RTX IO is, probably just Nvidia trying rebrand Direct Storge but it's the same thing. Nvidia bragged about cause that's what Nvidia does, they hype up and sell you a GPU now but with features you can't use for 2 years
