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.

  • Metro 2033
    • Extreme Settings: (Very-High Quality, AAA, 16x AF, Advanced DoF, Tessellation, 180s Fraps Chase Scene)

Metro 2033 Extreme Quality Settings

Cost Analysis: Metro 2033 (1680x1050)

  • $142 Radeon HD 5770 1GB costs $8.88 per FPS
  • $167 GeForce GTX 460 768MB costs $8.88 per FPS
  • $180 Radeon HD 6850 1GB costs $7.20 per FPS
  • $188 Radeon HD 5830 1GB costs $9.95 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 GPUs truly thrive on the newest DirectX-11 video games - so long as PhysX special effects is disabled. With all settings being equal, the Radeon HD 6850 again 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. At 1680x1050 resolution with extreme quality settings, the Radeon HD 5770 produced 16.0 FPS in Metro 2033 compared to 18.9 with the Radeon HD 5830, while the Radeon HD 6850 produced 25.0 FPS. As for the 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.

# Why 7.25 on the value?sweatshopking 2010-10-22 03:50
this card produces frames at a lower cost than anything else you tested, based on your own scores. Why do you rate it a 7.25 on the value front?

# RE: Why 7.25 on the value?Olin Coles 2010-10-22 07:04
True, the cost per frame value was quite nice, but there were several factors I considered for the value rating and you've got to keep in mind that it's a subjective score. I didn't like that fan noise was slightly louder than the 6870, and the price seemed just a little higher than I think it should be. Again, it's only my rating, and you can ignore it if you feel differently about the cards' price.

At 16x10 resolution, Hd 6850 is actually producing 56.1 fps in the BF2:BC benchmark, better than gtx 460. A typo there, my guess.

# 5830David 2010-10-25 06:30
well I wish I'd read this before I bought a 5830. not really sure where the 5830 would have placed in this test, but I assume it would be just below the 6850. my options at the site I purchased it were 5770 $139, 5830 $179, or 6850 $199. my motherboard doesn't have pcie 2.1 on 2.0 but I'm not sure if that would influence my choices.

2.1 on 2.0 should read 2.1 only 2.0

# 5830 wasn't greatsweatshopking 2010-10-25 07:02
the 5830 would come in quite a bit below the 6850, and with much higher tdp, and noise. It was a lackluster part, and that was one of the reasons for the refresh. that being said, it's still better than my 4850, so enjoy it!

I've actually got several results tested on the 5830, but didn't include them because this model is being phased out. I'll update the article with what I've got.

# RE: 5830David 2010-10-25 08:05
so my next question is how will my system likely perform. I'm upgrading from a 8800GT OC to a 6850 reference card on a P43 ICH10 MB a E8400 cpu with 4GB of Dual Channel DDR2 1066 Ram and a 3gbs Sata HD, onto a 1680 x 1050 22" LCD via DVI

should be able to play pretty much anything on high, at that resolution.

# RE: RE: 5830Olin Coles 2010-10-25 10:23
At that resolution, it should nearly match the 1680x1050 results I produced in this review.

That's good news. I've updated the test summary sections with 5830 performance results.

thanks, looks like it's $20 well spent to go from the 5830 to the 6850. besides the FPS increase, I will also get a overall better quality controlled product with a couple of extras that I probably won't use LOL.

How can the EVGA GTX460 be so much better than a normal one?

# Massive OverclockBruceBruce 2010-11-12 23:34
It's overclocked by the factory from 675 MHz to 850 MHz, giving it a pretty substantial (25% +) kick compared to stock cards.

# RE: Massive Overclockpero 2010-11-13 14:39
Is it physically different too? If a consumer overclocked a non-overclocked GTX460, would the results be the same?
Report Comment
 
 
# RE: RE: Massive OverclockOlin Coles 2010-11-13 15:49
Nope, it's just been overclocked. The results would be the same for any GTX 460 overclocked to those speeds.

# RE: EVGAOlin Coles 2010-11-13 08:49
Please see the Test Methodology section for specifications, but the reason it's better is because of a strong factory overclock.

# Will it work with my mobo?Ethan 2011-11-24 20:22
Hi. My motherboard has a pci 2.0 slot, not 2.1. will this card work?

Im currently running an amd msi r5770 hawk.

also, how much power does it need to run crossfire?

# RE: RE: AMD Radeon HD 6850 Barts Video CardOlin Coles 2011-11-24 21:06
It will work just fine with PCI-E 2.0, and since each card uses 140W expect to use 280W in CrossFire.

I have a 750 watt power supply. A 1 terrabite segate 7200 rpm hdd 8 gigs of ddr3 1333 Corsair Dominator ram, and an x fi titanium sound card. do you think that there would be enough power to run cf or should i check and see how much power each thing takes individually?

Thank you very much for the response

Your 750W PSU will be more than enough for CrossFire on that system.
