DX11: Metro 2033

Metro 2033 is an action-oriented video game with a combination of survival horror, and first-person shooter elements. The game is based on the novel Metro 2033 by Russian author Dmitry Glukhovsky. It was developed by 4A Games in Ukraine and released in March 2010 for Microsoft Windows. Metro 2033 uses the 4A game engine, developed by 4A Games. The 4A Engine supports DirectX-9, 10, and 11, along with NVIDIA PhysX and GeForce 3D Vision.

The 4A engine is multi-threaded in such that only PhysX had a dedicated thread, and uses a task-model without any pre-conditioning or pre/post-synchronizing, allowing tasks to be done in parallel. The 4A game engine can utilize a deferred shading pipeline, and uses tessellation for greater performance, and also has HDR (complete with blue shift), real-time reflections, color correction, film grain and noise, and the engine also supports multi-core rendering.

Metro 2033 featured superior volumetric fog, double PhysX precision, object blur, sub-surface scattering for skin shaders, parallax mapping on all surfaces and greater geometric detail with a less aggressive LODs. Using PhysX, the engine uses many features such as destructible environments, and cloth and water simulations, and particles that can be fully affected by environmental factors.

NVIDIA has been diligently working to promote Metro 2033, and for good reason: it is the most demanding PC video game we've ever tested. When their flagship GeForce GTX 480 struggles to produce 27 FPS with DirectX-11 anti-aliasing turned two to its lowest setting, you know that only the strongest graphics processors will generate playable frame rates. All of our tests enable Advanced Depth of Field and Tessellation effects, but disable advanced PhysX options.

    • Extreme Settings: (Very-High Quality, AAA, 16x AF, Advanced DoF, Tessellation, 180s Fraps Chase Scene)

Cost Analysis: Metro 2033 (1680x1050)

  • $167 GeForce GTX 460 768MB costs $8.88 per FPS
  • $180 Radeon HD 6850 1GB costs $7.20 per FPS
  • $220 GeForce GTX 460 1GB costs $10.68 per FPS
  • $240 Radeon HD 6870 1GB costs $8.42 per FPS
  • $260 EVGA GTX 460 FTW 1GB costs $9.89 per FPS
  • $262 Radeon HD 5850 1GB costs $11.29 per FPS
  • $292 GeForce GTX 470 1GB costs $10.21 per FPS

Test Summary: There's no way to ignore the graphical demands of Metro 2033, and only the most powerful GPUs will deliver a decent visual experience unless you're willing to seriously tone-down the settings. Even when these settings are turned down, Metro 2033 is a power-hungry video game that crushes frame rates. Although Metro 2033 offers advanced PhysX options, these settings are available only to NVIDIA GeForce video cards and disabled for our tests.

As demonstrated in Mafia II, the AMD Barts GPU truly thrives on the newest DirectX-11 video games - so long as PhysX is disabled. With all settings being equal, the Radeon HD 6850 outperforms both the 768MB and 1GB versions of the GeForce GTX 460 as well as the Radeon HD 5850 that's been competing with the 6870. As for the VisionTek Radeon HD 6870, it surpassed the factory-overclocked EVGA GeForce GTX 460 FTW video card as well as the much more expensive GeForce GTX 470.

# Overclocking SWServando Silva 2010-10-30 17:54
Hi Olin, I know MSI's doesn't support GPU over-voltage, but have you tried the newest version of Sapphire Trixx? Maybe you could get a pre-release version from them, as I've seen those cards overclock a lot with some extra-voltage.
Thanks for the Review.

Had planned to but two GTX-460's in December, but now I'm not sure. These don't do CUDA & Phys-X do they? I wonder how they scale with two on-board?
Is the CUDA and Phys-X features enough to shoot these down?
Gonna have to wait to see what develops. Can only afford an VERY occasional buy, so I want to get the best bang for the buck when I do.

Some people really enjoy PhysX effects in their games, and use CUDA for encoding media files. Others don't, and so it becomes a point of preference.

Keep in mind that you can buy two 1GB GTX 460's for around $340, while two Radeon HD 6870's will costs $480. This doesn't exactly put them in the same price segment, so cost becomes a major factor.

460 1G seriously is not in the same league in terms of performance with 6870.

and where do you get 1G 460 for $170?

Thank you for reiterating the point I made over and over in this article: it takes a lightly overclocked GTX 460 to compete with the Radeon HD 6870. A heavily overclocked EVGA GTX 460 FTW puts the 6870 to shame, however.

You can buy 1GB GeForce GTX 460's at NewEgg for $170, although some now also offer rebates.

I really don t see why someone should buy this card over a gtx 460 1gb hawk for example. In a price performance POV. It cost most and the diference ain t worth it.

# Great cardRudaxx 2010-11-01 12:24
Yes i bought two of these Amd 6870 and put them in crossfire. These are great cards, With Amd you can have and use a card effectively for more than two years, but with nVidia up to one year and you become obsolete, they are hot and very loud and who cares about cuda and physix i prefer Havok. Besides 90% of games are Havoc and they work great, not like physix in mafia 2 where you need an extra card to make it slightly more stable, with one it lags. I've never had problems with ati cards or their driver but with nvidia its a whole other story. By the way if you type "nvidia driver problems" on google you get 8 million results.

# RE: Great cardJack 2010-11-01 12:43
You're right that the 6870 does seem like a great card and a worthy successor to the HD5770. Every benchmark I have seen shows the 6870 performing with and in some cases outperforming the GTX 460. Although, I game with a single Gigabyte GTX 470 SOC and haven't noticed any of the issues with PhysX you mentioned. By the way, if you type "ATI Driver Problems" into Google you will get nearly just as many results (7.2 million when I checked). You say that after one year nVidia cards become obsolete but I was still using my old BFG 8800GT 512MB card I got back in the summer of 08 until I upgraded to the Gigabyte GTX 470. That's 2+ years of great use and 0 driver problems. Either way, both sets of cards, AMD and nVidia, are impressive. Anyone, looking to buy either the HD6870 or the HD6850 should also consider the GTX 460 1GB, and look at performance benchmarks, heat, and power usage before coming to an informed decision. BTW, I am really interested in the GTX 580 vs HD69XX cards.

What are the physical w/h/d dimensions of the 6870?
I am looking to put this into my case, and need specs.
Sorry, I can't find specs anywhere online.

# Same as it ever was....BruceBruce 2010-11-18 20:36
...with apologies to David Byrne. This is a reference card, and will be the same size as many of the other cards released at the AMD launch.

Height: 115 mm
Length: 245 mm
Width: 35 mm (Dual-slot)

They're right there in the middle of page two. I even included the Radeon HD 6850 dimensions. If you read the article, you can't miss it.
