Mussels posted a thread on PhysX and the conclusion, with which I agree, is that it is in fact largely irrelevant.
Alienbabeltech is also griping.
And I agree, it isn't really that relevent. However, as I already said, it wasn't like nVidia is asking them to do a multi-page write-up about PhysX and CUDA, just list them in the specs of the cards. A reviewer shouldn't be leaving out features of a card just because they don't find them relevent, a good review will at least mention them, and let the reader/customer decide on the relevence.
If a review was listing the features of a card and completely ignored the fact that it had a VGA port on it, I'd laugh in the reviewers face. And if they responded with "I don't think VGA is relevent anymore, so I ignored it" I'd laugh harder.
Like I said, I only seem to hear it from off the wall sites that want to make a name for themselves. The only exception seems to Anandtech and according to The Inquirer also HardOCP. Of course Anandtech wasn't blacklisted, as they did actually get invited to a GTS250 briefing and given a GTS250 sample. Of course nothing actually came from HardOCP about the issue, and the same Inquirer article was full of anti-nVidia lies(such as the price of the GTS250 being jacked up, while the Anandtech article even states it is actually $50 cheaper), so can we even believe that HardOCP was ever blacklisted? Oh, and what do you know the Inquirer article was from out favorite anti-nVidia full of shit author - Charlie Demerjian...
Im wondering if the pressure from nvidia is the reason that on ATI card reviews on TPU "no cuda/physx" is cited as a negative. Cause i cant understand that someone who decides to buy a card for its price/performance for gaming will ever need or even consider cuda or physx, not to mention cuda or physx isnt an option for board manufactures, it was never an option for them when manufacturing them, so criticising the card or manufacturer every single time on this when they make an ATI card simply doesnt make sense to me.
The same logic could be used to say that ATi was pressuring W1z to put "No Support for DX11" on ever nVidia review in the ~6-months between the launch of the HD5000 series and Fermi's launch. And before that, listing "No support for DX10.1". And really both features, to this day, are pretty much irrelevent. In fact I think there might be more PhysX games at this point then there are DX11 games...
Oh, and on his reviews of the GTX295's he puts "Built on SLI technology"
as a negative! Holy shit, he's bad mouthing an nVidia technology! That is worse then not even putting it in the review. Why has nVidia not blacklisted him? And in ever review of a GTS250 he says "No real product innovation"! If your theory is correct, that nVidia puts pressure on reviewers to give them good reviews, and blacklists them for saying anything bad, how has W1z not been blacklisted?
