As BFG noted, this is actually being discussed in the other thread on this subject in here.

Benchmarking the Benchmarks
Crysis built-in demo report: Min 21 / Max 47 / Avg 33
Measuring the same exact demo with Fraps: Min 26 / Max 71 / Avg 46
Crysis built-in demo report: Min 25 / Max 54 / Avg 39
Measuring the same exact demo with Fraps: Min 32 / Max 72 / Avg 51
Strange, isn't it? It's getting more exiting.

Benchmarking the Benchmarks
Then he reported his findings. First up is HD 3870 X2. According to him, running the built-in benchmark gave vastly superior scores, compared to the scores he got using Fraps in real time. According to him,Originally posted by: Kyle Bennett
Canned Testing with Crysis
Crysis represents what is probably the most graphically challenging game on the market right now that is enjoying a fairly large install base. Luckily enough it comes with a built in GPU benchmark that pretty much anyone can run, and they do...a lot. Even large sites like Anandtech exclusively relied on this canned benchmark for testing Crysis in its recent ATI Radeon HD 3870 X2 review.
Crysis ships with a built-in GPU benchmark, unfortunately the game is still too stressful to run at the highest quality settings so we're left running at the "high" defaults with no AA and at only two resolutions.
I am not sure if this is supposed to point the reader to any type of real world expectations at all, and it leaves me a bit confused, but Anandtech does go on to say this as well:
The last driver drop ensured that the 3870 X2 was actually faster than any single NVIDIA card in our lineup. At 1920 x 1200, the X2 is around 18% faster than the 8800 GTS 512. You'd need a pair of these X2s or faster in order to actually run at smooth frame rates at these settings unfortunately. It looks like the perfect card for Crysis still doesn't exist.
Does that mean if I play Crysis at 1920x1200 with the settings Anandtech used, my game on the X2 should run 18% faster than the 8800 GTS 512? Again, I am a bit confused here as to what the value of the information is.
Using real world gameplay, we come to much different conclusions at HardOCP about settings we can utilize and still play Crysis comfortably.
Canning H Benchmarks
All of this has left a lot of people very confused. And rightly so. You have a multitude of sites telling you that a 3870 X2 is ?faster? than an 8800 Ultra and HardOCP is telling you that the card does not perform up to 8800 GTX levels. The above is not to pick on Anandtech, but obviously it is the highest profile site to conduct ?canned? testing like this and its editors have openly defended their methods.
We decided to use the same canned Crysis benchmark and see how it compared to our own real world gaming testing of Crysis and see if we could understand all the results a bit better.

Next up is 8800 GTX. Once again, the same exact demo gives vastly superior numbers when run using Crysis' built-in benchmark.Originally posted by: Kyle Bennett
What you are looking at above is the built in ?GPU? Crysis benchmark that you have seen so many people run and report numbers on. The settings used above are EXACTLY the settings that we used for real world in-game testing here on the 3870 X2. It is also the same exact hardware and driver setup. That said, this canned demo has to stand on its own since we cannot replicate the exact demo in real world gameplay (we?re getting to that, be patient), but we can run the canned demo in REAL TIME and record the framerate with FRAPS.
The ?Real Time Timedemo FRAPS? data you see is gleaned from running the canned GPU timedemo in real time, and recording the framerate with FRAPS. The ?Traditional Timedemo Benchmark? results are as you might expect from running in timedemo mode where the recorded demo runs as fast as it can till completion then gives you your benchmark scores.
So to put it simply, one is the canned GPU demo run real time and the other is the demo run in timedemo benchmark mode.
Now what you will immediately notice is that the two sets of results using the Crysis canned GPU demo are not even close to the same. Simply running the timedemo as a traditional ?timedemo benchmark? gives us a 38% increase in average framerate over running the canned demo at real time speed using the 3870 X2. Average framerate increased 38% going from a real time canned demo to a traditional ?fast as it can draw it? timedemo benchmark. Same demo, same settings, same hardware, same driver.

The fact is that we cannot responsibly compare real world gameplay to the Crysis GPU canned timedemos since it is impossible for us to put together a real world FRAPS-monitored run through that mirrors the canned timedemo. We can however put together our own comparable real world Crysis run throughs and record them so we have custom demos. After we use FRAPS to record our real world gaming Crysis run though, we can then ?timedemo benchmark? that real world run though for comparison. It is also worth saying that this is not easily done as Crysis presents a long list of obstacles when it comes to recording real world demos. After a week of trials and a lot of practice, we finally got to a place where we could pull repeatable real world gameplay run throughs. You only get one shot at recording a ?good? real world run through to later use as a demo. If you screw it up, you have to start over.
