    "Cernynator" would be great for the PS4 GPU! Hasta la Vita, Baby! :lol:

    No, it's 30 fps for the standard UHDTV resolution (which is QuadHD).

    Still, the timing for HDMI 2.0 is a bit tight but not impossible.

    I'm more interested if it it will support 1080p60 in 3d (ie. effectively 1080p120). That's the format we really need for stereoscopic gaming at the moment.

    The graphics would be too gimped. A clean 720p120 would do nicely imo. Which if the rumored 1080p60 fps PS4 versions become reality, could meet that target.

    I agree.

    However, if they were to be compared I'd say Xbox One has a more showy trailer along with boosted contrast/saturation.

    PS4 however has more natural lighting and effects. The polygons are also far less obvious (if at all).

    Sony has already said the DS4 features "enhanced rumble" but I don't know that they've gone into too much detail on that...

    From the DF article on Sony's GDC talks

    No mention of additional motors just greater programmability for what's there already.

    Do we know how much resources are reserved for system in PS4?

    Nothing official I think, but it seems likely it will match XB One, at least to begin with, because they can't take more away later. KZ SF tech slides have it using a bit less than 5GB, as MS have available for X1

    I guess that the "7GB for games" is only a rumor.

    Speaking of the controllers

    interesting breakdown on the ONE controller


    also lab technician on reveal show said there was a 15% communication speed improvement over 360

    I don't get how 50% higher specs translates to 100% higher framerate? Assuming both consoles are clocked the same, the basic argument should be more 40 vs 60fps (or 30 vs 45) at the same res, or different resolutions at the same framerate, no? I don't doubt certain techniques may favor once architecture over another, but I'm just going on basic GPU specs.

    If we're all just exaggerating for effect, then ignore me and carry on. :razz:

    AFAIK, not even GG knew about the upgrade to 8GB until fairly recently. 3GB of GDDR5 dedicated to the OS seems excessive. When the PS4 was rumored to have 4GB of GDDR5, the rumor was just 512MB for the OS. After we knew it was going to be 8GB, the new rumor was that 7GB would be available for developers. 1GB seems more likely to me... 2 at the most.

    I think they're going by the ROP count (16 vs 32), assuming double the fillrate will double framerate if all else remains equal.

    They may push for 1080p vertical res only, or a dynamic resolution to get closer to 60 fps. Maybe it could be a toggle in the menu settings too. "HFR mode - Slightly lower resolution at times, but improved frame rate".

    When gaming on PC, I find anything above 30fps makes a huge difference in controls and feels. Would definitely appreciate if PS4 versions made this happen, even if not a locked 60.

    I don't think they're really going to reserve 3 GB for the OS, 2GB max should be fine- they're not running Windows simultaneously with the Game OS or anything like that. Nor do they need memory for Kinect voice and skeletal tracking databases.

    And MS does all of what they're currently doing in 2GB, the remaining 1GB is only reserved for future use and not being currently used for anything.

    So I really don't see why Sony will match them on the memory reservation when their OS seems more lightweight and their vision for the device is more focused than MS' all encompassing entertainment box.

    And what of the bandwidth necessary to actually feed those ROPs?

    Ok, and how would this exact same thing not be done on X1's display planes though? That's the entire reason they were designed based on the leak and the actual patent for them.
