Lost Planet 2 DX11 Benchmark Results

A decade has passed since the first game, and the face of E.D.N. III has changed dramatically. Terra forming efforts have been successful and the ice has begun to melt, giving way to lush tropical jungles and harsh unforgiving deserts. Players will enter this new environment and follow the exploits of their own customized snow pirate on their quest to seize control of the changing planet.

  • 4-player co-op action: Team up to battle the giant Akrid in explosive 4 player co-operative play. Teamwork is the player's key to victory as the team is dependent on each to succeed and survive.
  • Single-player game evolves based on players decisions and actions
  • Deep level of character customization: Players will have hundreds of different ways to customize their look to truly help them define their character on the battlefield both on- and offline. Certain weapons can also be customized to suit individual player style.
  • Beautiful massive environments: Capcom's advanced graphics engine, MT Framework 2.0, will bring the game to life with the next step in 3D fidelity and performance.
  • Massive scale of enemies: Players skill on the battlefield and work as a team will be tested like never before against the giant Akrid. Players will utilize teamwork tactics, new weapons and a variety of vital suits (VS) to fight these larger-than-life bosses.
  • Rewards System- Players will receive rewards for assisting teammates and contributing to the team's success
  • Multiplayer modes and online ranking system
  • Exciting new VS features- Based on fan feedback, the team has implemented an unbelievable variety of Vital Suits and new ways to combat VS overall. The new VS sytem will have a powerful impact on the way the player takes to the war zone in Lost Planet 2

Test A:

The primary purpose of Test A is to give an indication of typical game play performance of the PC running Lost Planet 2 (i.e. if you can run Mode A smoothly, the game will be playable at a similar condition). In this test, the character's motion is randomized to give a slightly different outcome each time.

Lost_Planet2_1920_Test_A.jpg

In Test A of Lost Planet 2, we see a familiar pattern. That is, the newest games are implementing the latest software technology and the newest graphics cards are optimized to handle exactly that. The HD 6990 does quite a bit better here than it did with the H.A.W.X. 2 benchmark. The GTX 460 SLI takes a surprise second spot with the CrossFireX HD 6870s right behind. This test runs very fluidly with the 6990, better than I've ever seen with any individual or combination of cards. I saw none of the usual "slowdowns" during the test with the PowerColor HD 6990 that I have seen before, with lesser AMD cards. They've always remained during the second and third runs of the benchmark, so it wasn't a map loading issue. It occurs at the beginning of scene two which is the most demanding, no matter what card is installed. In fact it's usually tougher than Test B. For simplicity's sake, we are reporting the average result, as calculated by the benchmark application. It is not an average of the individual scores reported for the three scenes.

The new GeForce GTX 560 Ti is the most impressive performer in this challenging test, providing the best frame rates for the money. The results for the Radeon HD 5870 show why you don't want to use anything but the most recent DX11-capable hardware for these new games. The developers are really warming up to the enhanced visual tools that are available in DirectX 11, and hopefully we'll see more titles like this that make the unreal, real. As long as you are happy with the story lines, characters, scoring systems, etc. of these new games, you can enjoy a level of realism and performance that was only hinted at with the first generation of DX11 software and hardware. I keep thinking of some of the early titles as "tweeners", as they were primarily developed using the DirectX 10 graphics API, and then some DX11 features were added right before the product was released. It was a nice glimpse into the technology, but the future is now.

Test B:

The primary purpose of Test B is to push the PC to its limits and to evaluate the maximum performance of the PC. It utilizes many functions of Direct X11 resulting in a very performance-orientated, very demanding benchmark mode.

Lost_Planet2_1920_Test_B.jpg

Test B shows completely different ranking than Test A, and for some reason the Radeon HD 6990 completely lost its way in this benchmark. It just ties with a pair of HD 6870 cards, where it should have at least a 30% advantage. Don't forget that the HD 6870 GPU is not "half" of a 6890, like the HD 5xxx series was, where every step up in the product line was a doubling of the die size and transistor count. The 6870 has 1120 shader cores, compared to 1536 in each of the 6990 GPUs, not even close to a 1:2 ratio. So I wasn't expecting a massive performance gains by moving up to the HD 6990, but I expected a little more than nothing!

The sea monster (I can't quite say "River Monster" for some reason...it reminds me of River Dance) is a prime candidate for tessellation, and given the fact that it is in the foreground for most of the scene, the full level of detail is usually being displayed. The water effects also contribute to the graphics load in this test, making it just a little bit tougher than Test A, overall.

In our next section, we are going to continue our DirectX 11 testing with a look at our most demanding DX11 benchmarks, straight from the depths of Moscow's underground rail system and the studios of 4A Games in Ukraine. Let's take a peek at what post-apocalyptic Moscow looks like in the year 2033.

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.

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!

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.
