Nvidia accused of cheating over graphics tech

Recommended Posts

"ATI IS MAKING hay while the sun shines after an article at Driverheaven more or less accused Nvidia of cheating. We referenced the web site article earlier today in our hardware roundup.

It's also worth looking here for background on this matter.

We said that what we saw when we were in Geneva with Nvidia was a clear difference between the code that was running PS 3.0 path and a referred system that was running PS 2.0 code.

ATI says that CryTek's representative told it that what Nvidia showed us in Geneva was a 2.0/3.0 path versus 1.1 path.

The key message is that Shader model 3.0 and 2.0 look exactly the same, the ATI representative added.

In a developers' mail that we also received, it added that there is a possibility that the 3.0 path might be slightly faster in same cases on some hardware - an obvious reference to Nvidia.

ATI also claims that its hardware will run faster then Nvidia's anyway and he added: "It's pretty much impossible to make a sm3.0 game look noticeably different to a sm2.0 game, which is why Nvidia was comparing the 2.0/3.0 path with a 1.1 path."

A CryTek representative responded on this matter with this answer: "Was Nvidia showing SM3.0 vs. SM2.0 or SM1.1?" He replied to his own question by saying that Nvidia was showing 3.0/2.0 vs. 1.1."

This is how it all started.

All I can ascertain so far is that ATi are claiming Shader 3.0 isn't important. Because they haven't released a product that supports it yet. O...k.

The Driverheaven article is of limited empirical value (for starters FutureMark are as bent as a nine bob note). Artificial benchmarks, inperceptible IQ variations and beta drivers. Meaningless to real world cost/performance/featureset comparisons.

"You’d be hard pushed to say which image is optimised with the mipmap square. To me though, its not a matter of what I can see so much as the fact that this changing of textures is happening behind the users back. I have selected maximum quality on my £400 graphics card and I fully expect it to have Max Quality…not lesser quality than a much cheaper competitiors product." (article)

Fuck sake, it's hardly 3dfx-style shenanigans is it. Have a wank.

I think people that accuse NVIDIA of cheating are also the ones that accuse decent Counter Strike players of using Aimbot.

nVidia have done it before though thats the point.

I read about this a bit on a another website, regarding the test where that tester says nVidia is cheating again. However, this other website claims, it's not that simple, and all that can be said eventually is that (currently) ATi's High-Quality setting renders better "images" than nVidia's High-Quality setting.

This will help somewhat in framerate performance as I understand it, but that doesn't necessarily make it cheating because it isn't written black-on-white what quality-level should be achieved using a certain setting in the drivers. Because there is no definite reference, it's not cheating.

Well, that's what I understand of it anyway :rolleyes:

I imagine the game would play similarly if the floor looked like something from Tron, but you wouldn't fell like you were squelching through a damp cave then.
