DX11: Batman: Arkham City

If there was ever a game that showcased the growing gap between game consoles and high-end gaming PCs, Batman: Arkham City is it. In this dystopian near-future, part of Gotham City has been walled off as an enclave for criminals (rather like Escape from New York). It's a 3d-person action game that adheres to story line previously set forth in Batman: Arkham Asylum, and is based on an updated Unreal Engine 3 game engine. Batman: Arkham City is a DirectX 11 title that uses multi-threaded rendering to produce life-like tessellation effects.

One annoyance with the game is that all game settings must be made through a hidden application called "BMLauncher". Once you've made your settings, though, an in-game benchmark provides the feedback you'll need to tune your system's performance.

  • Batman: Arkham City
    • FXAA (medium), DirectX 11 features, medium tessellation, medium Detail, Dynamic Shadows, Motion Blur, Distortion, Lens Flares, Light Shafts, Reflections, Ambient Occlusion, PhysX off


The AMD Radeon graphics cards are at a disadvantage here, since, like Arkham Asylum, Arkham City is a showcase of PhysX effects, which can be directly accelerated by NVIDIA cards but not by AMD cards. I left PhysX turned off for this test but if your Radeon-equipped rig is running an Intel 2500K or higher processor, consider turning it on: the PhysX will run on the CPU but modern multi-core CPUs have enough power to do a credible job, and you'll miss out on some really cool effects otherwise.

The HD7770 matches the performance of the HD 6850 here.

Cost Analysis: Arkham City (1920x1200)

  • $139.00 GeForce GTX 460 costs $2.67 per FPS
  • $190.00 GeForce GTX 560 costs $2.84 per FPS
  • $330.00 GeForce GTX 570 costs $4.07 per FPS
  • $135.00 Radeon HD 6850 costs $2.55 per FPS
  • $240.00 Radeon HD 6950 costs $3.16 per FPS
  • $180.00 Radeon HD 7770 costs $3.46 per FPS
  • Test Summary: Careful coding and design of the Arkham City graphics engine means that even lower-end video cards can produce playable frame rates at high resolutions.

    People please wait again for another 3 or 4 months to get this product come to its true place ... i m getting frustrated with such high pricing strategy from AMD

    I might be wrong, but I did not see if this card allows control of the vCore. This is a must have option IMHO. Not all cards allow this. For Example, the VisionTek 6850's are not able to up the voltage. Not even flashing the BIOS with a custom profile will work.

    Right now the various hacking tools (MSI Afterburner) for the AMD GCN graphics cards are in a pretty primitive state. I wasn't able to get voltage control working for the 7970 and 7950 cards, and didn't even try with the 7770. I'm sure this will change in the future, though.

    # No physx a con?Pat 2012-02-16 10:09
    I don't understand why bmr keeps giving AMD cards a negative because they have no physx. It's not like they even have a choice since physx is proprietary. It's like holding nVidia cards responsible because they don't support eyefinity. I respect your opinion on including this, I just would be interested why you choose to include that.

    According to NVIDIA, PhysX is an open standard anyone can write to. They were saying this as early as 2008. There are doubtless behind-the-scenes reasons nobody else has implemented it; and there are competing physics engines like Havok and Bullet, but it all begs the point: it's a significant advantage to NVIDIA cards since so many games use it. Your Eyefinity example isn't a good one since NVIDIA provides equivalent functionality with their "Surround" feature. I tend not to weight either of these too heavily since only a tiny fraction of users run triple monitor setups.

    I know you don't push it too much which I appreciate because there are enough people that don't understand what it means exactly. I don't begrudge nVidia for owning physx but as far as I know it will only run on nVidia hardware. Sure, the software may be open for development but if it isn't able to run on anything but nVidia cards doesn't that make it being an open standard kind of pointless? As for the eyefinity example. I realize it's not the clearest example but my point was that it's an AMD technology that nVidia doesn't have. You bring up that nVidia has surround however surround isn't exactly equivalent considering anything I can find about says it supports a max of three monitors whereas eyefinity supports 6. I'm not saying one or the other is better just that they're different in functionality. I can see your point though and the more I think about it, the more I see the reason for including physx. I just haven't seen it come up as a topic on here before. It would be interesting to see a review on physx, not in pure numbers but rather simply did it look/feel much better with physx? Hey, maybe with enough pressure AMD would pick it up and use it. I can dream huh?

    How much of a difference PhysX makes depends of course on how well the developer uses it in a game. Probably the best showcases for the technology are the Batman: Arkham Asylum and Arkham City titles. The games are perfectly playable without PhysX but it really adds to the atmosphere when it's enabled.

    You're right about Surround being limited to 3 monitors, which is probably why AMD has been showing off 5-monitor setups of late. I know one or two people with triple monitor setups, but the only 5-monitor setup I've ever seen was an an AMD press event. Impressive, yes; real-world utility, well...

    Well I like the battle that's shaping up with this gen of cards. nVidia has their advantages, AMD has theirs (primarily first strike). I just hope nVidia punches back hard enough that they force AMD to drop prices. This HD 7770 would be just what I need to replace the 8800GT that recently died in my spare computer. Unless you know something about the next nVidia cards you'd like to share ;)

    I like the looks of this card. It's striking.
    But the price turns all of that off immediately. If the price were to fall a ~good~ bit, I could see running a pair of them in my A8-3850 Vision PC. The low power usage and lower heat appeal to me.

    Yeah I think if they can get down to $130-$140 that'd be great. I mean, yeah I'd like it to drop more but I don't see that happening unless nVidia REALLY kicks their butt in this segment

    I read through all the reviews, and I found one of these cards used for $110, would that be a good price for it?

    New, the cards are currently $144 at Newegg. So you could save $30 with the used one, I suppose.
