| ethomaz said: I will make the things more clear to you. The biggest problem with PS3 is the BD is slower than HDD... so the load is better when you sent the data from HDD to RAM... PS4 didn't have this problem... the DB player is fast than any mechanical HDD... so the devs will never use the HDD to cache the data before sent to RAM. Mora RAM means the devs can load more data from BD to RAM while you are playing the game... with few amount of the RAM you always works with the RAM alreay full and have to discard data before to load the new one (loadtime). Now with a lot of RAM you have the choose to load the data to the RAM way before to use it... I meam you can use 1GB of RAM just to load future data to avoid loading times. In any case in PS4 the devs will never use the HDD over the BD player... the BD is fast... and there are RAM enought to make cache... that can change if PS4 uses SSD but I don't believe that. A good tech to avoid load times using the RAM... while playing the old map already start to load the new map to RAM.... with a lot of RAM you will always have more future data already loaded in the RAM. |
The PS4 Optical drive is not faster than any mechanical hard drive, you have 10,000 RPM drives which are stupidly fast, some even paired up with high-speed flash memory.
And it certainly doesn't have an edge in access times either, have lots of small files? Those transfer rates will plummet.
As for not caching to the Hard drive? Well. That would be a silly move, installing a game to the hard drive means they can access BOTH the Hard Drive and Optical Drive in tandem, Optical Drives are actually pretty good at doing sequential reads, not so much on random reads which the Hard Drive is actually very good at and SSD's are perfect at, being able to stream from BOTH at the same time would be a wise move, which for some titles the PS3 even does.
Yes I'm also aware of the "Streaming" technology.
But you also need to load up the initial world with all it's dependancies before streaming can begin, I.E. Expect to wait, then successive loads will be much shorter, then you will get "pop in" where blurry textures suddenly become sharp... etc'.
Then after a couple of years after the consoles release developers will probably start hitting a memory wall and they will not be able to cache the next level whilst the player is playing the current level, that's the nature of static hardware and people wanting better graphics unfortunatly, something has to give and Load times will be the first to go unless developers perform some tricks like I outlined prior and then some.
But please. Don't claim that BD is "super" fast, it really isn't. It's good for some things like sequential reads, but you would be dreaming if you think it can compete with a Hard Drive.
