Remember the original Detonator 40 launch?
They claimed improved shading performance, and many people were amazed by the huge Nature increase.

Now we know where it comes from, I guess - it's pretty much back to the Pre-Detonator 40 scores. :(
Cheating is nothing new at NVIDIA Corporation, it seems...

"Cheating" has been around in the Detonator's since the 12.xx releases- it's just there was too much of a fanbase to actually dig in and do any research at the time- any offerings of evidence were quickly discounted and hot air/windy retorts are all that ever came of them.

On topic of this current 2001 issue, the basics of research still need to be performed. Noting a ~10% delta in performance by running a benchmark two consecutive times isn't exactly earth shattering- and I'd also say is pretty close to the margin of error of 3dmark2001se (hell, a fresh reboot and re-run can often times effect the total score by 1000). The Nature test is of the most interest given it's huge delta.

What needs to happen with this scenario is the basics of homework- screenshots, comparisons, isolation of what (if any) visual differences may occur.. etc.etc. One can only raise a red flag if adequate controls are in place and if the differences can be isolated.

I've already said I want an anti-cheat 3dmark01se version...
What does AntiDetector.rts do? Does it prevent shader detection?
Though it looks only Game 4 is, umm, optimized a lot. The other optimizations don't seem to provide much benefits (aps and dragothic about 10%, the rest of the scores look identical). Do the optimizations change image quality?

I am sure this is no real suprise. We all know that when only 3dmarks scores of the nature test shot up nV was going some optimizations there. But its nice to have some data now to back it up. I wonder if all of those who "defened" sides on this 3dmark fasico because 3dmark2003 was "lame", "a bad benchmark", ect will do now that we know that even 3dmark2001, every ones pride and joy, was subjected to a simular process.

Depending on the driver versions, I've had my GF3 do scores in the low 30s to mid-50s in 2k1 nature test. Naturally, pun not intended, I hoped these score improvements were due to GENERAL optimizations in the driver, not GT4-SPECIFIC optimizations.

Naturally, it would be very disappointed to find I've been pinning my hopes of increased scores to nothing but an illusion. ...Especially since the general attitude towards Nvidia standards has been very high in the past.

interesting but not hugely suprising, i always though the 70-80 fps scores were a little too high.

Still, the 8500 went from 20ish at launch and is now about 45-50+ might be interesting to see if any of that is iffy.

Are you sure???

I remember that GT4 was always a strong point for the 8500 because it had a better Vertex engine to start with. their scores were also good on the Hardware lights tests.

I do remember a relatively earily 8500 driver build that added "non trivial" performance increases in some shading tests. Don't recall if it was GT4 or the synthetic shading tests, or both.

I must caution the use of the word "cheat" as it applies to 3DM2K1.

FM has stated (in the "Help" file & the audit.pdf) what a "cheat" is in 3DM03, but I fail to see the word "cheat" used in any literature released by MO/FM concerning 3DM2K1 usage.

Carry on, but CYA (cover your a$$) in the terminology used. :wink:

Yeap I agree others to be shown "optimizing" most likely.

I guess my point was a lot of people said that since they did not like 3dmark2k3 then its ok for this to happen. I tried to show them that logic is flawed.

- Detonators have 73-element table of "recognized" applications
- ~50 "recognized" shaders
He simply wrote rivatuner-patch hich will "block" detection routines in the driver.
IMHO just a matter of time to see how 8500 fps in GT4 jumped ahead...

The 8500 drivers at release were terrible under XP. They were lurching around like a drunken sailor on my system until ATI released a fix for 'systems with large amount of memory' in January '02. Performance was awesome across the board after that.

http://www.nvnews.net/articles/david_kirk_interview.shtml+David+Kirk+optimize&hl=en&ie=UTF-8

David: I’ve heard this mentioned before, and I haven’t really dug into it too much, since it’s not a very realistic real-world example. The lit triangles test in 3Dmark2001 renders a lot of offscreen (invisible) triangles, which results in a lot of what I would call “meaningless computation”. So, I’m not sure exactly what capability is being measured in the test. It’s not visible. Often, benchmarks test Software or Hardware code paths that are not general and are not commonly used. We at NVIDIA don’t make it a practice to optimize our pipeline for specific benchmarks - we want to provide high quality and high performance on a wide variety of useful and entertaining applications, rather than just getting a good score. Ask yourself (or, better yet, ask ATI) why Radeon 8500 performs well on this one test, and poorly on many other 3DMark2001 tests.

http://firingsquad.gamers.com/hardware/kirkint/page3.asp

It's very easy for people to target synthetic benchmarks and optimize their drivers and hardware for them. That does not add anything to real world performance. You need to optimize your drivers to make game engines and API features go faster, not just specific game titles.

.... what ATi make with these 2 p.sh. 2.0 is hardly "shifting" ......

Interesting that both ATI & Nvidia got a large improvement in Nature with optimizations (though Nvidia did the better job :x ) without sacrificing image quality (or did they?). I'm wondering what exactly they did - shader optimizations probably won't cut it (as those are relatively simple PS 1.1 shaders) and GT4 is usually quite bandwidth limited (due to the alpha-tests).

There's no drop in GT2/3 in 3Dmark03 which use PS1.4 contrary to GT4 which uses PS2.0. So there's some optimisation for PS1.4 in 3DMark01 and not in 3Dmark03.

PS 1.4 is not used in any of the game tests in 3D Mark 2001. The advanced pixel shader test in 3D Mark 2001 uses PS 1.4, if supported, but it has no bearing on your score.

Well it's not true, it's used in the advanced pixel shader. But you are right i confused with it ;). Thx you for correcting me.

Anyway, the "optimisation" on nature doesn't seem to be the same as the one on GT4 on 3DMark03

Anyone consider that ATi optimized the PS1.0 into PS2.0 (or PS1.4 for 8500/9100) for the higher FPS w/o loss of IQ? Could simply be the ATi cards use the highest PS they support & I don't see anything wrong with that in 3DM2K1. I hope they do it for my games too! :D

15-Jun-2003, 21:31
Yes ATI is probably doing more than re-ordering in 3Dmark 2001, they are possibly even replacing the shader with a superior PS 1.4 version since Futuremark never included PS 1.4 in scoring during the benchmarks 2 years of existence...a really big joke.

Is image quality reduced, I would say absolutley not...and I personally have no problem with optimizations that don't reduce quality, as those examples could also be used in games.

RussSchultz
15-Jun-2003, 23:35

The point of 3dmark is to have a consistant test. You can't change the contents of the test without invalidating the scores already taken.

This is why they came up with 3dmark03, instead of simply updating 3dmark01.

Yes, I agree, the changes done by ATI probably make much sense on modern day cards, however its not what was being tested.

PS1.0 is used in 2K1 GT4. Changing to 1.1, 1.2 or 1.3 wouldn't be a performance improvement. PS1.4 &/or PS2.0 would tho'. *If* they use PS1.4 for 8500/9100 & PS2.0 or PS1.4 for 9500+, that *could* explain the results (IMO).

It *could* simply be that the drivers call for the highest PS supported. I find nothing wrong w/that even in a benchmark as it gives a true 'real world' optimization that would be applied 'across the board' & wouldn't be 'application specific'.

I don't know if that is what *is* happening, but it seems that might be what is happening. :wink:

HTH & it's just my .01 :wink:

You can't "call for the highest level pixel shader". (well, not when 3dmark2001 was written)

Unless you're using a high level shading language (like Cg, or the HLSL in DirectX, or GSLang, etc), you code your shaders using 'assembly'.

If a driver is recognizing a particular shader PS1.0 assembly sequence and replacing it with an optimized PS1.4 assembly sequence, its "cheating".

Even though, in the real world, you'd likely find developers using that optimized PS1.4 sequence, it isn't what the benchmark tool is asking for.

Just like the partial precision hints that some people think that Futuremark should have implemented, it doesn't change that fact that they didn't. Going behind the benchmark's back and doing it there isn't the right answer.

'Call', 'code', 'assemble' ... whatever, you get the gist.

This is 2003. 3DM2K1 is old. It was written for PS1.0 DX8 (max) for the score. Running anything over a GF3 'Classic' is a *cheat*. :wink:

Allowing a driver to 'real world' (not application specific, but for everything) optimize 2K1 for the newer cards isn't wrong > it is SOO right, IMHO. What better way for a consumer to see the difference in the new hardware & it's supported API's? 8) The caveat being: as long as it doesn't lower IQ. 8)

gah, i cant believe this.
It is still a CHEAT.
However, there are shades of grey.
IF indeed all ATI has done is rework some shaders so the output is mathematically identical but it executes faster on ATI hardware, then that is STILL A CHEAT in the context of 3dmark01.

Is it less wrong than a cheat that lowers IQ?
Hell yes.

Does anyone know if nvidia's optimizations in 3dmark2001 yielded in a drop in IQ?
Replacing PS 1.0 with 1.4, or 2.0 should not drop the IQ.

Well, no it shouldn't.

But AFAIK there is no indication that is what nvidia has done. For R300 cards, ATI has replaced some PS1.0 shaders with PS2.0 shaders. I haven't read anywhere that nvidia was also converting PS1.0 shaders to PS2.0/PS1.4 shaders.

edit: corrections.

Ok, whatever. The point still stands.

Where was it proven that nvidia was converting PS1.0 programs into PS1.4 or PS2.0 programs?
