    Alright, now we have had the chance to play around with the 3DS for a good 10 months, I'm sure most of us have played one the best looking game on the system, yep I'm talking out Residents Evil: Revelations demo. Now we have a good insight what the system is capable of.

    Feel free to post screenshots/footage that impressed you, discuss its GPU and how it's features are used in game and other aspects of the system such as sound or whatever and if you like, criticise the system if it lacks in a particular area.

    There's not much we know about the inner specs, We can speculate using screenshots and games that are release. Just so you know the known facts are....

    128MB FCRAM, contains 2 dies split in 64MB each.
    Some dual core ARM CPU with unknown clock speeds.
    DMP Pica200 GPU model that we don't know which and unknown clock speed.
    DSP, its own dedicated sound chip unlike the DS.
    6MB VRAM, stated from 3dbrew.

    Note: I don't want people bringing up Vita in this thread, we all know it's a much more powerful handheld out of the two, lets not state the obvious and keep it down to what the 3DS can achieve.



    Edit: Regarding the Pica200 GPU more info thanks to coto and puregamer

    Warning: Spoilers inside!

    All the specific figures related to CPU and GPU performance like clock frequency or Mpix/s are pure speculation and/or blind copy-pasting.

    The only new thing we've recently learned is that 3DS is actually capable of applying fullscreen AA in a real game (in 2D, though). Up to now, almost no game used AA (SSF4 had it on some objects in cutscenes; it was also applied in Pokedex, but's that's a toy, not a fully blown game).

    Is this supposed to be a copy of the thread on Neogaf?

    I long for the day where my Nintendo console's games have smooth lines.

    We have known about AA since launch actually.

    And AA wasn't applied in the pokédex app.
    I've played both RE:revelations and SSFIV and I can say that both games uses AA when the 3D is off,
    though in Street Fighter you have to go inside the menu and disable 3D from there before it starts running with AA.

    By cutscenes you mean in game when the camera zooms out and the fight starts right?

    If 3D wasn't shut down in the menu before you would enter a fight the game would play with AA off as long as it was in game footage.


    So both RE and SF play jaggie-less, not that it matters on a small screen but it's a neat feature.

    Hope that cleared some things up.

    Also,

    http://www.dmprof.com/english/e_products/e_pica200_lite/

    There's the "PICA 200 Lite", aimed to handhelds/low power consumption. I bet 3DS has a custom one, like this

    The 3DS has two types of AA: 2x horizontal AA and 4x AA, which the developer can choose to turn on or off. The Pokedex app uses the first, for example.
    If the game doesn't have AA, that can only mean that it uses too many resources as it is. You should realize that when using full AA in 3D mode, the 3DS has to render at 8 times the screen's resolution.

    OK, so Capcom is using the the latter type, because their games are the smoothest I've seen.

    That's why it is so impressive that they've managed to have AA in Resident Evil.

    The 3DS got a RAM boost shortly before launch which would mean that first-gen games wouldn't have been able to take advantage of the extra RAM. We should see better-looking games later on as a result of that. Not to mention the whole extra core that was apparently unlocked to devs.

    And there's the possibility that Nintendo could raise the clockspeed of the PICA200 for devs just like Sony upped the PSP clockspeed to 333MHz after a firmware update.
    I've seen AA being used before Revelations. Zelda OOT 3D had it in 2D mode. And from what I heard, Zen Pinball does 4X super-sampling AA in 3D Mode.

    Aliasing is the jagged effect on lines. Anti-aliasing removes those jagged lines.
