Crysis Warhead Analysis
Crysis Warhead, the sequel to the original that follows the same story from a different perspective, does a great job of improving on the Crysis engine in terms of balancing performance and improving playability with a still-forward-looking engine (though we lack the native 64-bit runtime of the original game). We push the settings pretty high in spite of the fact that we don't turn them all the way up. Everything is set to "Gamer" quality with the exception of Shaders which are set to "Enthusiast" level.

Like CoD, Crysis favors NVIDIA hardware. The settings we're rocking require more than a single Radeon HD 4850 or GeForce 9800 GTX+ even at 1680x1050, so it's likely that many gamers will be running at lower settings than these. As with CoD, SLI sweeps this benchmark in terms of performance. The Radeon HD 4870 CrossFire pushes up against the GeForce GTX 260 SLI setup, but the core 216 or an overclocked GTX 260 setup would easily put some distance between them.

In terms of scaling, SLI looks better at lower resolutions while CrossFire puts the heat on as resolution increases. Despite the fact that the 4850 scales at over 77% (which is very good), the higher baseline of the NVIDIA cards keeps this from making the impact that it could. At the same time, configurations with two 4850 cards perform on par with the GTX 285 and offer much better value.
1680x1050 1920x1200 2560x1600
Our performance data and our value data show that in this case, AMD's approach to single card multiGPU on the high end is effective. The 4850 X2 2GB can be had from newegg for less than $300 which is more than $50 cheaper than a single GPU NVIDIA solution that gets you the same performance where it counts.
It's interesting to note that AMD two card solutions tended to scale better than the single card multi-GPU options here. Where memory is a limiter, we see our higher memory single card options scaling better. In this case, it looks like memory isn't as large a bottleneck as something else. We can't say for certain, but our guess is that it's the PCIe bus: with both cards getting a full x16 slot, each GPU is able to communicate more efficiently with the host and it seems that this is beneficial to Crysis performance.
At 1920x1200, the only single card solutions that remain playable are the GTX 280 and GTX 285. Getting good performance on a 30" monitor requires either a GTX 295 or 2x GTX 280/285s. Nothing else passes the test at the highest resolution we tested.

It really is a great looking game for an MMO. It's not the most played MMO around, but it is definitely the easiest to test. There is an area near the beginning where the player is alone in the environment and it's always the same time of day and all that stuff ... It takes out some of the factors that make getting consistent data out of other MMOs incredibly difficult.I've never had any real "issues" with it or with the results either. It's been very consistent as well. It does add value, and it's clear that games can be coded in a way that looks really good and perform like this one, so we feel it's important to getting a better feeling for what's out there and what's possible.

Not really a big deal, but could you cut out the offhand game review comments when introducing benchmarks? I.e.: "Crysis Warhead, while not the best game around..." It feels out of place in a hardware analysis.SiliconDoc - Wednesday, March 18, 2009 - link
And Derek disses Far Cry 2 and Oblivioin where nvidia slaughters ati - then derek praises Bioshock where ati has an edge.Derek CAN'T HELP HIMSELF.
SiliconDoc - Wednesday, March 18, 2009 - link
Oh yes, and below don't forget the age of conan that favors the ati card - Derek can't stop drooling all over the place.Then come to COD, where nvidia once again slaughters - red blood everywhere - Derek says "do we really need another war game~" or the like.
Derek is red fan central and cannot stop himself.

This game is poorly programmed in the first place, does it deserve to even be included in the benchmark tests? Yes, it has the programming necessary to for the test but they're poorly programmed.IKeelU - Monday, February 23, 2009 - link
The fact that CryEngine 2 is taxing on today's hardware (and that Crytek will no doubt use derivatives of it in future games), makes it very useful in benchmarks. I hope reviewers keep using it. But by all means, feel free to disassemble Crytek's binaries and point out their code's weaknesses.Yeah, I thought not.

what do u mean they shouldnt include crysis warhead??? its the seminal game to see how graphics performance is to get an idea of how a particular video card will perfrom in the future. Cryengine2 is the most advanced graphics engine on the market. If a video card can provide 30 fps on a cryengine @ your resolution, then its good to last u for atleast 2 years.Razorbladehaze - Wednesday, February 25, 2009 - link
Yeah.... NO.I totally disagree with it being the most advanced. It is a decent game engine especially for benchmarking, but....
In all reality the STALKER Clear Sky revamped xray engine is far and away more advanced and superior in almost every way. It is about the same or better in regards to taxing the system (low frame rates does not necessarily translate to the game is taxing the system.). Being that these are also used in similar FPS titles they would make a interesting comparrison.
I would really like to see Anand include or swap a clear sky bench (there is a premade one available), for the Crysis or Crysis warhead. Either way no big deal many other sites post results with a CS bench that view all the time.

i'll take care of it.Stillglade - Monday, February 23, 2009 - link
I would love to see more info about the 4850 X2 1GB version. For over $50 cheaper, is the 1GB memory enough to compete? Is it worth paying 24% more for the 2GB version that you reviewed here?
