The way you are arguing seems that the PS4 gives total control to any game all the time (close to what the 360&PS3 do today). How will PS4 record 15min gameplay? How will PS4 suspend game and swap to menu? How will PS4 download games at beckground? I can´t belive Sony is building a single task experience with the PS4. If so, the X1 is de facto a far superior tech. |
Yeap... when you are saying the game running everything single pixels is using the GameOS (PS4 didn't have a GameOS but we will call it that from now)... when you shift to the AppOS in PS4 it pause the GameOS and release resoruces for the AppOS so the AppOS when in use can use the GPU but when the GameOS is running 100% is reserved to it.
Xbone not... the AppOS alreasy uses 10% of the GPU everytime and you run both at the same time... there is no pause or change in resources because the AppOS needs to use GPU to run... so GameOS can use only 90% of the GPU today.
That's the difference... now your questions.
How will PS4 record 15min gameplay? Cerny said this feature is free up of any system resource... it don't use CPU, GPU or SysMemory. It is in a Gamasutra interview with Cerny I will find it to you late.... I guess there is a dedicated processor to do that task.
How will PS4 suspend game and swap to menu? PS4 reserves two CPU cores (rumors) and ~2GB RAM (rumors) to run the AppOS while your are playing games... the AppOS gets in some mix of suspended mode because it stop most of the OS processing but continue to run some apps like the CrossGame Voice Chat... when you swap AppOS the PS4 pauses the game and release more resources for the GameOS, when you go back to GameOS it enter in this mixed supended mode and the GameOS have full access to it resources again.
How will PS4 download games at beckground? There is ARM dedicated processor for background tasks.
6-core CPUs, 100% GPU and ~6GB of RAM is all reserved for Games only.
