Noobmatron - AMD/PhysX?

DamoTourettes · 2 Dec 2011 at 10:02

Massive noob question, but am wanting to go AMD 7000 series when they come out from a single GTX 580, and am wondering if they'll support all the lovely PhysX/destruction/visual eye candy etc stuff that the Nvidia cards do? Do they have a similar standard?

Cheers

No. PhysX is NVIDIA only because AMD is anal about using anything NVIDIA develops.

I think it's more to do with Nvidia not allowing it on AMD hardware, and AMD are going with that "Bullet" open standard thing that isn't looking to be doing anything right now

PhysX is a waste of time anyway.

They won't support it directly but there is a way of enabling it. Problem is you need an AMD card and a backup NV card to achieve this

You can force it to run off the cpu, but it will hurt your frame rates to say the least.

That's not AMD supporting it though really, as PhysX is still ran off the Nvidia card.

Total nonsense, the only thing anal on the subject is your comment!

Are you one of those undercover employees paid to infiltrate forums?

If this comment was even remotely true, the phys-x hack would alsohave to hack the AMD drivers when it hacks the NVIDIA driver when it enables phys-x to be used with an AMD card!

As it stands AMD disable nothing from their end regarding Phys-x!

They don't disable PhysX because they never enabled it in teh first place. It's not nonesense. The facts are these: NVIDIA said AMD and any third-party is free to use PhysX. But AMD have no interest in using it.

You're speaking crap.

This has been discussed before on these forums. And people have conjectured on the reasons behind AMD's decision. You're entitled to your opinion but what I said is true. If that bothers you so much it's not my problem.

LOL

physx gets disabled if an AMD card is detected in the system, that's actual fact don't you know

Would you mind linking a relevant article? If that's actually true it's news to me, so I'd be interested in reading more

As far as I've ever read, the NVidia drivers will disable physx support if an AMD card is present (hence the need for the special drivers).

Saying "what you said is true", and that "these are the facts", does not make them so.

1) Buy an AMD card for rendering
2) Buy a cheaper Nvidia card for PhysX
3) Install drivers
4) Install hacked PhysX drivers
5) ?????
6) Profit!

But seriously, using hacked PhysX drivers with an Nvidia card is the only way to use PhysX with an AMD card.

There's no point arguing why AMD doesn't support PhysX... both companies are blaming each other about the support. Nvidia says AMD isn't interested, AMD says Nvidia won't let them. Now who's telling the truth

?

Do you actually walk about wearing the Mad Scientist Green Glasses xsistor all day?

You really need to take them off once in a while mate.

Except a bit of googling would've shown you that this is old news that has also been talked about on these forums before.

http://www.bit-tech.net/custompc/news/602205/nvidia-offers-physx-support-to-amd--ati.html

AMD just likes to pretend to be altruistic, with their holier-than-thou attitude. There were other reports that followed this one up saying AMD was not interested in PhysX. They also bitched a lot about PhysX and continue to do so. But funny thing is AMD was thinking of buying Agiea before NVIDIA did. and now suddenly the grapes are sour and nobody should want those grapes.

AMD's also been going on about releasing hardware physics for a while now, but have nothing to show for it thus far. Same thing with their 3D. They do lip service to the glory of open technologies and yet fail to understand the key underlying philosophy behind open-ness: keeping progress alive without stifling it.
NVIDIA is actually making progress with their techs, closed or not. While AMD is dicking around a lot.
Take CUDA, 3D and PhysX as examples. I use two of those and my work has depended a lot on CUDA. If I had been waiting for a AMD's vague promises I'd have lost years waiting for AMD's so-called open approach which only serves to hold things back rather than serve the true purpose of open technology.

Yes, Nvidia really wanted AMD users with a dedicated Nvidia gpu to use phys-x, they even created the infamous 'time bomb' in the driver:

'Versions 186 and newer of the ForceWare drivers disable PhysX hardware acceleration if a GPU from a different manufacturer, such as AMD, is present in the system.[14] Representatives at Nvidia stated to customers that the decision was made due to development expenses, and for quality assurance and business reasons.[15] This decision has caused a backlash from the community that led to the creation of a community patch for Windows 7, circumventing the GPU check in Nvidia's updated drivers. To counter this patch, Nvidia implemented a time bomb in driver versions 196 and 197 that slowed down hardware accelerated PhysX and reversed the mavity,[16] but an updated version of the patch removed all unwanted effects.'
