Unreal Engine 3 ported to Windows RT

ARM-based Windows tablets are a couple of months off, and their gaming potential just got a nice boost from Epic. Unreal Engine 3, the basis for everything from Batman: Arkham City to Infinity Blade, has been ported to Windows RT. This isn’t some cut-down version of the engine, either. Nvidia’s blog post announcing the port makes clear that WinRT tablets are getting a full-fat PC implementation of the engine.

The embedded video below shows the Epic Citadel demo running on an Asus Vivo Tab RT tablet, which pairs a Tegra 3 processor with a 1366×768 display. According to the narrator, the frame rate is in the 35-40 FPS range.

Epic Vice President Mark Rein claims developers will be able to port their Unreal-based games to Windows RT with little trouble. The code is available to engine licensees already, and it will be interesting to see how many developers take advantage. Porting a game over to Windows RT is one thing, but adapting traditional control schemes to a touchscreen interface is another challenge entirely.

    And today suddenly everyone loved the idea of Windows RT and Windows tablets….

    • albundy

    I still dont get how they were able to do this. how is tegra 3 running the textures and shaders? or is DirectX out of the picture?

      • Arag0n
      • 7 years ago

      It is likely to be DirectX based if WindowsRT involved…

    Hook up Xbox 360 controller, bam you just usurp MS’s little kingdom… Especially if these things have micro-HDMI outs on them…

      Maybe these ARM tablets will be running just XBLA games…. wait… That is why Xbox Live is part of the Windows ecosystem unfolding this Oct. 26

      they have HDMI, that’s the point. just like the windows phones. wp8 will support video out on the phones, so just get a decent smartphone and win.

        • Bensam123
        • 7 years ago

        I don’t think the point of a tablet or smartphone is to move the video to a bigger screen, but it’s nice to know these have mini-hdmi out.

          • Arag0n

          I know plenty good streaming apps for Windows Phone and iOS that would be nice to be able to use plugging your smartphone to TV in a very easy way with my already placed HDMI cable….

      Playing angry bird with a thumb control is your nirvana ?

      This thing is like 5x slower then an xbox360…
      Good luck getting a real AAA game working on this thing.

        • Bensam123
        • 7 years ago

        I wouldn’t want to play FPS’s with thumb controllers, but some people do it. Good luck getting AAA games to run on a X360… I think the performance gap isn’t as big as you think.

    This demo run at a rock solid 60fps on my 5 year old PC using Flash.

    If you use UT3 via Flash you also get cross platform reach, including Linux.
    [url<]http://www.joystiq.com/2012/08/27/unreal-engine-3-citadel-app-runs-on-linux-now/[/url<] Its weird that Linux support was done by Google... This artificial fragmentation will only benefit company like Unity3D.

      • sweatshopking

      it’s a cell phone chip?

        • sschaem
        • 7 years ago

        It is, because It surely is no match for a GPU from 2005…

        But that wasn’t my point. My point is that this effort was only necessary because MS doesn’t have Flash running on RT.
        If they did, this: [url<]http://www.unrealengine.com/flash/[/url<] would already run at 35-40fps on Windows RT

          • sweatshopking
          • 7 years ago

          so,you’re upset that winrt, like EVERY OTHER mobile platform (including android), doesn’t have flash (which is killed on mobile) support? you’re somehow blaming MS for that? ADOBE killed it.

            • Ricardo Dawkins

            Metro IE supports Flash based sites that are approved by Microsoft.

            • sweatshopking
            • 7 years ago

            that’s true. it’s a stop over until it’s totally killed.

            Liar. Microsoft kept flash off WinRT, and used that as leverage to get access to the flash code, so now they have their own Microsoft version of flash.

            Makes me wonder what they’re going to do with silverlight in the future.

      Weird how? Google’s engineers are all familiar with Linux, I believe (it might even be a job requirement), while Adobe’s developers develop mostly for Windows and Mac OS.

      Google has a vested interest in maintaining chromium and chrome for their internal Goobuntu Ubuntu Linux derivative (they get to eat their own dog food), and them maintaining Flash for Linux to work well with their browser as opposed to Adobe treating it as a red-haired stepchild makes a lot of sense to me.

      But perhaps you know something that I don’t?

    But I’ve been told Windows8 is bad for gaming.

    …so confused now…

    /s

      • sschaem
      • 7 years ago

      Games that look so 2004 and run at 35fps, not even in HD resolution.

      Is that the FUTURE of gaming ? Or is this just another ‘angry bird’ platform ?

      The concerning part is that people writing windows game are now going to dumb down their game to have them work on windows RT.
      Same issue that plague ‘us’ with console ports.
      But then Tablets are not even close to console HW, so we might be faced with windows8 causing games to take another step backward.

      And thats without the moral issue of microsoft walling off distribution all to themselves taking 30% of all of the developers revenue, before they get to pay bills, salaries and taxes.

        • sweatshopking
        • 7 years ago

        what? it’s a full 3d game, using the STILL most popular 3d engine in the world running on a CELL PHONE chip… i’m not sure how you equate that to ANYTHING about “dumbing down” anything. NOTHING has to be dumbed down. this is proof that FULL games run on winRT. all you gain is the ability for functional games on windows tablets, that will work on x86 and arm easily by coding for winrt.

        you clearly have no idea what you’re talking about.

        tegra 3 is a CELL PHONE CHIP. this has nothing to do with x86 performance. i realize you are worried they might stop making crysis 3 to instead make crysis Tower defence, but i don’t think that’s likely.

          Unfortunately you may notice the tech demo given is not a game. Surely it’s graphically brilliant for a tablet but when it comes to actually making a game there are a lot of other pieces to the puzzle. As mentioned it’s running at about 35-40 FPS which is nice, but you start throwing in AI opponents, physics and lots of sound like you do in a PC game then I highly doubt you’ll still have a fluid 35-40 FPS. This is the point you start dumbing down the game so it’ll run smoothly on a tablet, and thus is detrimental to PC gaming on the whole.

            i’m not sure i agree. scott seem to think infinity blade is AMAZING. YOU CALLING HIM DUMB? my point is that this isn’t going to END pc gaming. it’s going to allow for easy deployment on a variety of systems. and don’t forget, this is the BEGINNING. how powerful is ARM going to be in 2-3 years? THIS IS ABOUT THE FUTURE, and in that sense, it’ll be good for programmers.

            • Deanjo
            • 7 years ago

            Truth be told, there is very little AI in infinity blade. Each foe has about a maximum of 6 different moves which is pretty much randomly deployed.

            • sweatshopking
            • 7 years ago

            i’m not disagreeing with his AI concerns. that’s a cpu concern on all platforms. play civ v.

      it hasn’t changed. Everything else gets 60 FPS at a higher resolution.

    Nice! Glad nvidia is pushing the win8 platform!

      • Madman

      ARM chips is one of their main markets nowadays, if I understand correctly.

        • Arag0n
        • 7 years ago

        Yup, and I believe WinRT for gaming will be huge once nvidia releases a Tegra with kepler GPU

          • Madman
          • 7 years ago

          I think it will need a lot more.

          WinRT needs to build the app base. It’s empty as of now and not really Windows.
          WinRT devices need to get some old-skool input/output love, like keyboards, mouses, 30″ displays and high quality audio.
          ARM migration to 64 bit might be necessary soon, to overcome 4GB RAM limits (2GB per app?)

          Until then, WinRT is an Angry Birds platform, not a gaming station, no matter how powerful the GPU is.

            • Arag0n
            • 7 years ago

            So, no one was gaming seriously before 2008, right? Because 2GB was the norm then. There is plenty headroom for gaming with lower specs. Hey, XBOX games are limited to 256Mb and still there is plenty nice games.

            • sweatshopking
            • 7 years ago

            you’re talking about winrt on arm? winrt is the metro environment on x86 and arm. x86 supports all the things you’re referring to.

            [url<]http://en.wikipedia.org/wiki/WinRT[/url<]

            • l33t-g4m3r
            • 7 years ago

            WinRT is not Metro. It is a cross-platform application architecture. Metro and all Metro Apps run in WinRT. You can’t run Win32/x86 apps in WinRT. Win8 Pro runs BOTH WinRT and Win32, so you are essentially running two operating systems at once. HURR. Oh, and WinRT is locked down and all apps must come from Microsoft.

            Win8 ARM is not an angry birds platform. It supports WDDM 1.2 and DXGI 1.2. This Unreal demonstration proves it is a credible platform for games. Of course, you are buying all your apps through Microsoft, and open source programs are locked out. This is the future of PC gaming because it could theoretically eliminate piracy. Which also means no Libre Office, or any type of competition. Do you people really want to go down this path? You’re screwing yourselves and everyone else along with you. This is exactly why Valve is porting Steam to linux. Wake UP. Fire in the hypothetical building! Danger, Will Robinson!

    A lot more pixels to draw than the iPhone 4 running Epic Citadel (and more than the iPad 2, even) but that’s pretty lame performance for a fairly old demo on brand new not-even-released hardware. I hope there’s more optimizing to do yet.

      • BobbinThreadbare
      • 7 years ago

      Tegra 3 has been out for a while.

        • derFunkenstein
        • 7 years ago

        WinRT hasn’t though.

          • BobbinThreadbare
          • 7 years ago

          [quote<]brand new not-even-released hardware.[/quote<] There's nothing that new about this hardware.

            • derFunkenstein
            • 7 years ago

            poor word choice. So sue me!

        • Alexko
        • 7 years ago

        And wasn’t all that impressive even when it was first released, so getting this kind of performance out of it is quite a feat. I suspect that although this is supposed to be the “full Unreal Engine” some settings may have been lowered, and some effects disabled, perhaps, but in the end it looks very good nonetheless.

        I’d still much rather play games on a PC, but that’s a different issue.

      • Deanjo
      • 7 years ago

      Especially when it runs so smooth on an iPad 3 with more pixels to push.

        • tbone8ty
        • 7 years ago

        The ipad3 has a better gpu than tegra3 and it looks pretty smooth to me!

        • sweatshopking
        • 7 years ago

        is it the full version of UE3? idk if it is or not. also, what fps do you see on the ipad? this is interesting in that it allows for full ports of other ue games. this is positive news, and it shows that winrt is a competent enough environment for gaming. that alleviates some of my concerns.

          • Corrado

          This would be nice with a KB dock and a mouse for travel. If it can play real games, with real input devices, this is win win for everyone and makes it much more desirable. No need to carry a PS Vita or 3DS around to play games when your tablet can do the same thing + internet + productivity.

            • sweatshopking
            • 7 years ago

            pretty much this. hdmi out, wireless mouse and keyboard, i’ll be able to HON anywhere. luckily hd3000 plays on and civ v decently, so intel graphics are enough for my usage. the next couple years are going to be great!

            • travbrad
            • 7 years ago

            If you are going to carry around a KB and mouse why not just carry around a laptop?

          • Deanjo
          • 7 years ago

          Infinity Blade uses the full UE3 (as do a few other games for the iPad like Epic Citidel, N.O.V.A 3, Batman: Arkham City Lockdown, etc) and have no problems on the iPad 3.

            • sweatshopking
            • 7 years ago

            i didn’t say they had problems. i asked about frame rates. you were hinting that it runs better on ipad, and i’m wondering why. do you have something to back it up, or is it “your feelings”?

            • Deanjo
            • 7 years ago

            I quote epic when I say “insane framerates of the new iPad”.

            • sweatshopking
            • 7 years ago

            ok, so you’re not implying it’s better. my misunderstanding. ♥

            • Deanjo
            • 7 years ago

            I never said anything was better. I was implying that even on more demanding hardware there is little need for performance concerns with UE3.
