Battlefield: Bad Company 2 Test Results

The Battlefield franchise has been known to demand a lot from PC graphics hardware. DICE (Digital Illusions CE) has incorporated their Frostbite-1.5 game engine with Destruction-2.0 feature set with Battlefield: Bad Company 2. Battlefield: Bad Company 2 features destructible environments using Frostbit Destruction-2.0, and adds gravitational bullet drop effects for projectiles shot from weapons at a long distance. The Frostbite-1.5 game engine used on Battlefield: Bad Company 2 consists of DirectX-10 primary graphics, with improved performance and softened dynamic shadows added for DirectX-11 users. At the time Battlefield: Bad Company 2 was published, DICE was also working on the Frostbite-2.0 game engine. This upcoming engine will include native support for DirectX-10.1 and DirectX-11, as well as parallelized processing support for 2-8 parallel threads. This will improve performance for users with an Intel Core-i7 processor.

In our benchmark tests of Battlefield: Bad Company 2, the first three minutes of action in the single-player raft night scene are captured with FRAPS. Relative to the online multiplayer action, these frame rate results are nearly identical to daytime maps with the same video settings.

This is a game that favors the Green Team, without a doubt. Across the board, we've routinely seen competitive matchups where the NVIDIA card puts up better numbers. The Radeon HD 6990 finally gets a leg up for AMD and posts FPS numbers that are roughly 20 FPS better than the competition from either side. Of course, there is that $700 purchase price to consider... This is not as tough a benchmark as some others; the developers trod a fine line between juicing up the visuals and keeping the performance levels up. This benchmark does not utilize tessellation, so as in our DX10 testing, the strength of the newest GPUs in this area are not having an impact here. Don't worry; we'll see some results later that will show clear differences between the generations with some tessellation-heavy titles.

The little-documented feature in the basic game setup, which allows the application to choose which DirectX API it uses during the session, is not a factor here. All of the tested cards here are DX11-capable, and the game was running in DX11 mode for all the test results reported here. Even though this is primarily developed as a DX10 game, there are DX11 features incorporated in BF:BC2, like softened shadows. That one visual enhancement takes a small, but measureable toll on frame rates. It doesn't have as big an impact as aggressive use of tessellation would, either from the visuals standpoint or the computing perspective.

In the next section we use one of my favorite games, DiRT-2, to look at DX11 performance. Life isn't ALL about shooting aliens; sometimes you just need to get out of the city and drive...!

Well done Bruce. After all the effort, sacrifice, and no telling how many years of enthusiasm/experience you bring to the fray, I feel compelled to offer a sacrifice of my own. Since the card is out of warranty, I volunteer to take it off your hands for long term testing, say a couple of years, and deal with any and all warranty issues in your stead. I know, I know, my altruism knows no bounds.

(wink, wink, nudge, nudge)

Good job.

Thanks for the props, Robert. As for your boundless altruism, I'll go you one better. You put gas in my wife's car for the time that you have the card, and it's a deal. [%^)

I know this was written for the PowerColor card but I just received my HIS yesterday and installed it last night. I guess my bottle neck is my resolution and my monitor. I have a 28" 60Hz, 1920x1200 Hanns-G monitor with 3ms response. I just don't see the gain from this series and going back to my 2x 465 GTX Nvidias or my 2x 580 GTX's in SLI. For the ATI fans I also have 2x 5850's in X-Fire and they also run like beasts. Its kinda like having a Race Car that does 205+ MPH but because you live in a heavy school zone there are always police which limits your choice to either follow the law or get arrested (Kind of a bad analogy but I'm sure you get my drift).

So now I have spent $720 on this card, damn I need a new hobby, I've now spent over $2,500 on video cards in the last 6 months.

I'm curious what kind of games you're playing, because that could be an indication of your bottleneck. Anything will play Battlefield or Starcraft at high frame rates, but the same cannot be said for titles such as Metro 2033.

I'm playing Battlefield Bad Company 2 and a few other FPS games. I figured that was my problem. And BFBC2 is more CPU intensive, I playing Battlefield on my AM3 1090T 6 Core which is more than enough for that game. I need to start HA (Hardware Anonymous) for geeks, but I'm afraid it would be a blood bath of which brand name was better, lol.

# A thoughtCom-Tek Chris 2011-03-22 06:59
How come we are pitting this against the Nvidia 400 series and not a set of 560ti's in SLI or a a single 580 GTX? I notice that the scores are up against a set of 460 GTX's in SLI and a couple of 6xxx series in cross-fire mode but none of the big cards from Nvidia in SLI. Was this because of a price to power thresh hold? Or because of availability in cards? I know my 2 580 GTX's his the $1,100 mark when I purchased both so maybe it is unfair to compare it to a single card that is $400 less, but still it would be nice to have the scores posted for comparison for both sides of the fan base. Hands down though, I love this 6990, its fast, sweet, and feels like there is a lot of technology in it. Even Nvidia Fan Boys would be impressed with the sheer speed of this card.

If we had two of everything, we'd put them in SLI or CrossFire. Since one card arrives as another is ready to launch, we're restricted by deadlines and must move to the next project.

Do you have to send back the cards your given? If not what do you do with them? Or do I dare ask, lol.

Only a few products get returned, but it's a matter of finding time to review more than one product of the same series before the next arrives. These reviews take more time than you could imagine (I invite you to try sometime), and after one article in published a manufacturer usually has something new in our hands.
All of my video cards sit in a giant cardboard box, and get sold about 16 months after they've launched and gone EOL.

I have done Bench Marking in the past with all new hardware, always trying to squeeze that extra 100 points out, lol, I don't do much anymore just because of the time it takes. I am a business owner and there are days where I start at 6am and get home at 10pm only to find that I have a 1/2 dozen build outs that are to be done by the next am, so I pull a 24hr shift that turns into a good 36hr shift, lol, did I mention I have a wife and 5 kids?...................so the drama continues in the life of "Im a computer engineer/network security consultant/Father/Guy who likes to game/Guy who races cars in the SCCA in the season which is here now/Guy who builds computers and provides support for local residents and business's and also donates computers to new local schools that burnt down 2 years, lol, yes I love life and all it offers..........did I mention I love Chinese food and hot pockets?

Replace kids with friends, keep computer engineer/network security consultant/SCCA racer, and add target shooting enthusiast. Also replace Chinese food with Thai, and hot pockets for Wheat Thins, and we're on the same page.

Olin's spot on about product availability v. time to do the review. As Einstein said, "The reason time exists is so that everything doesn't all happen at once." My corollary to that is, "Space exists so that everything doesn't all happen at the same place."

So, check out Olin's HD 6990 reviews for comparisons to the GTX 570 and 580 cards. I was surprised that the 580 SLI didn't wipe the mat with the competitors. It was faster, but not in another league, you know....

I'm very curious to see how well NVIDIA manages the balance between electrical power, heat and processing power with their rumored dual-GPU card. At this stage of the game (40nm GPUs), there's only so much juice that you can pump through a single card and the winner is the one that's more efficient per watt. We'll have to wait another week or so, to see.

FWIW, I prefer Triscuits....LOL

My wife pushes the wheat thins/Crackling Oat Bran Cereal.....a lot! And I just tried Thai recently, the curry wasn't to bad. My goal is to lose 30 pounds this year. I just got over the Flu and I have kept 12 pounds of that off, lol, its going to be a good year. Now if I can just get my hands a new AM3+ 8 Core, another 6990 for X-Crossfire Mode, now that would finish the year off with a POW!

What PC Case do you have in that picture, I hope its not really expensive. If it is do you think you could link a cheaper Pc case?

It's a CM Storm Sniper, which I reviewed here: benchmarkreviews.com/index.php?option=com_content&task=view&id=398&Itemid=61

It's not cheap, unfortunately, unless you find a deal. The good news is that there have been a ton of inexpensive gaming chassis reviewd on this this site recently, and I'd bet at least half of them would be able to handle this card, at 305 mm long.
