Futuremark Replies to Nvidia's Claims
Nathan writes "Tero Sarkkinen, Executive Vice President of Sales and Marketing at Futuremark, has commented on the claims by Nvidia that 3DMark2003 intentionally puts the GeforceFX in bad light, after Nvidia had declined becoming a member of Futuremark's beta program. This issue looks like it will get worse before it gets better." ATI also seems to be guilty of tweaking their drivers to recognize 3DMark.
ATI also is crafty at tweaking their drivers to suck. They should be working on decent drivers instead of cheating on stupid benchmarks to get +1.9%.
I bought a Radeon 9700 Pro. The driver issues almost make it not worth the increased FPS over my Ti4400.
The refresh rate problem in XP is annoying as hell. ATI handles it even worse than NVidia, where you set your "maximum" refresh rate and your "highest" resolution, and it assumes that all lower resolutions can only handle that refresh rate.
There's no way to tell your ATI card, "My monitor can do 1280x1024 @ 85hz, but 1600x1200 @ only 75hz." You either get 75hz in everything if you want 1600x1200, or you get 85hz up to 1280x1024, and have to avoid 1600x1200 use lest ye risk getting "frequency over range".
NV handles it better with the driver, allowing you to set maximum refresh rates for every resolution individually.
These refresh rate tweaking programs don't help either, since half the games out there choke when you use them. PC 3d is in a bit of a sorry state right now, and I'm tired of it.

This whole episode has turned into a big mess. NVDA seems to be the bad guy in all of this. Their DX-9 product was delayed and their existing products where only DX 8.0*. The benchmark heavily favours DX-9 parts and NVDA's existing lineup was/is getting smoked in the benchmark by it's main (only) competitor. They decided to go on the offensive and try to kill off this benchmark. The 30 person company that produces 3D Mark have stood their ground against the multi-billion dollar NVDA. NVDA instead of admitting that their Pixel Shader is quite slow when running against 2.0 specs insteads tries to decieve and FUD their way out of it. Looks like they got more than just some patents when they purchased 3DFX...
Now they have painted themselves into a corner and how this will turn out is anyone's guess.
*DX8.1 has PS 1.4 which is actually much closer (AFAIK) to PS 2.0 than PS 1.3 (DX8).
AFAIK, ATI displays the graphics on screen properly, the drivers are just optimized for the benchmark. One could still consider this cheating. NVIDIA however does not display the graphics properly, it really does cut corners (literally) to get higher scores. ATI got an extra 3% from cheating. NVIDIA got a whopping 24% higher scores from cheating! take a look at the extremetech screenshots:

They do a good job of disecting the benchmark, and I'd have to agree that as a DX9 benchmark it fails.
Whatever, it's still just a synthetic mark and nothing more.
-- taking over the world, we are.
This quote is misleading. "DirectX9" alone means nothing.
We need to look at the new shader features offered by DirectX9, these are:
- Pixel and Vertex shaders 2.0 (supported by ATI R3xx line and GeForceFX)
- extended Pixel and Vertex shaders 2.0 (supported only by GeForceFX)
- Pixel and Vertex shaders 3.0 (no support until R400/NV40)
Now let's look at the features which are used by 3DMark03:
- Game 1: no shaders at all, only static T&L
- Game 2: vertex shader 1.1 and pixel shader 1.4 (which isn't natively supported by NVIDIA cards)
- Game 3: vertex shader 1.1 and pixel shader 1.4 (which isn't natively supported by NVIDIA cards)
- Game 4: vertex shader 2.0 and pixel shader 1.4+2.0
This means that:
-DirectX9 offers three new different shaders.
-Three of four 3DMark03 demos don't use new DirectX9 shaders at all
-Three of four 3DMark03 demos use Pixel Shader 1.4 which was introduced with DirectX8.1 and isn't natively supported by NVIDIA cards
-Only one set of new DirectX9 shaders are partially used in one 3DMark03 demo
Thus 3DMark03 shouldn't be called "DirectX9" benchmark. Following quote: "If hardware performs well 3DMark03, it performs well in all applications that use DirectX 9" should be changed: "If hardware performs well 3DMark03, it performs well in all applications that use Pixel Shader 1.4"
This happens so often in grade school I'm surprised the computer industry hasn't caught on to it yet. If you give students a copy of the exam the night before the exam, the only material they are going to bother to study the question-answer pairs on that exam, and may just remember what the answer to #6 is rather than even try to understand the question.
In order for a driver benchmark to be useful at all, it needs to be kept absolutely secret from the chip manufacturers before the test, and then once it is used and revealed that benchmark needs to be retired, because the next generation of testing should be designed to concentrate on the new features that the graphic card developers are expected to put in their next generation of cards that will be used in the next generation of games.
In short, the best benchmark will always be based on "that sure-to-hit game that's just about to come out."
