    Aspyr has updated Civilization V with support for the new mac pro, offering OpenCL frameworks to improve performance on NVIDIA and ATI chipsets in OS X Mavericks, as well as 4K resolution. The company says most Civilization V players should see faster game and visual performance as a result.

    Civilization V is available on the Mac from the Mac App Store [$14.99], Steam, and Aspyr's GameAgent digital store. The game is being offered for 50% off temporarily on the GameAgent store alongside the update.

    Update 8:53AM PDT 3/21/2014: A prior version of this post claimed that Civilization V takes full advantage of both video cards on the Mac Pro, based on information provided by Aspyr via a blog post and press release. Aspyr has updated its blog post and reached out to MacRumors to issue a correction.

    The Civilization V update does not utilize both video cards in the Mac Pro. An Aspyr spokesperson explained that the update "focuses on the OpenCL framework so that more processes are centered around the GPU, thereby reducing the overall memory footprint" and that the company "made the decision to focus on one card so that all other ATI and NVIDIA setups would benefit from the structure instead of JUST the Mac Pro."

    We have also updated this post with a full-resolution 4K screenshot of Civilization V.

    Wow. Civ in 4k. Astounding for someone who played the original Civ, which was may have been as low as 320 x 240!

    Cool! I was hoping games would start to support both cards without Boot Camp, but I'm surprised to see it start so soon.

    I wouldn't get one JUST for gaming, but my work machine wants to play sometimes!

    Score! Now I can finally justify buying a Mac Pro!

    Holy cow. It has enough performance issues in normal HD, but I guess maybe just maybe the Mac Pro can handle that.

    Is that picture in picture how it really looks? The UI elements are tiny by default! Pretty cool, good on Aspyr.

    I can't even get it to run at 2880x1800. It renders that many pixels but all the art is still pixilated. Does that happen for anyone else? (PS I have the Steam version)

    Does that mean they enabled Crossfire (which I thought the Mac Pro drivers couldn't do), or that they're using the other GPU just for compute tasks?

    Great. I'm buying another Mac Pro just for gaming.

    Brilliant. This makes Civilisation the least graphics intensive game that can benefit from the dual GPU in the Mac Pro :rolleyes: I wish they would have actually make some noteworthy improvements, like fixing their extremely slow load times/horrible save menu - and most importantly, extremely slow AI.


    From what I gather they are using the second GPU to decode compressed textures. It sounds like your typical marketing BS.

    But it's a start. There were tons of skepticism if companies would even bother to support the dual GPUs of Mac Pro. These are good news, hope more will follow Aspyr's example. Good job.

    Good job Aspyr, playing in 4K is an achievement, I applaud the work of optimisation behind! Hope to see other games with OpenCL and dual video card support.

    An update to Bioshock Infinite would be great.

    But with the added power of OpenCL, will the AI be just as stupid?

    It's nice to see them taking advantage of modern technologies, though I'm not sure how big a market there is for playing Civ V at 4k on a new Mac Pro.

    The 4k reference, is it about the amount you'll have to put in upgrades to play this game? :D

    I'm much more interested in the use of OpenCL than 4K support. I mean, lots of GPUs (and CPUs) support OpenCL, so that should benefit people who own iMacs and MBPs as well.

    OpenCL is a compute technology, not a graphics technology per se. Do we have any more information on how it's being used? Is it being used to power the AI? Effects like the ocean or whatever?

    Hey guys, our apologies but the blog post that is being quoted here has an error. The OpenCL update does NOT take advantage of the second card, but rather focuses solely on taking full advantage of the OpenCL framework so that iMac and MBP owners would see benefits as well. MacRumors and we will get the edit out asap.

    Springsup is right on with the tech. Essentially OpenCL (used properly) allows you to shift computing processes over to the GPU, thereby reducing the overall memory footprint of the game.

    We chose Civ V as the focus for this effort for two reasons:

    One, Civ V is by far the biggest game on the Mac. It was important to us that if we were to spend the time, money, and resources on an update that we knew wouldn't make any money, it really needed to benefit the most amount of users as possible.

    Two, Civ V would get the most benefit from a reduced memory footprint because of the way the game works. :apple:

    Our post has been updated to reflect this new information from Aspyr.

    It's kind of concerning that such an incorrect statement could emerge from the company. It's not a small error, but a complete 180.

    In any case, would it be a lot of work to use the second GPU for OpenCL tasks? I'm assuming you're using OpenCL for the texture decompression which is done with DX11 compute shaders in the Windows version. I suppose it would help if those textures are needed asynchronously rather than needing to keep the second GPU's work tightly in-sync with the game rendering on the first GPU.
