Nvidia Disables PhysX Support on Vendor Mixed GPU Setups – Driver Update 340.52 Onwards

Gregster · 7 Aug 2014 at 09:55

For those that want to use PhysX and run a hybrid system, have a read of this thread. My understanding (and only going by the posters) is that 320.14 is the best driver to use (which you can download from the nVidia site).

These are the games that work with the hack. Sorry, but it is the best I can come up with

Not offense Greg, but isn't that like asking "Why can't HD4850 or 9800GTX+ use dx11?"?

None taken

Who wants to use 2 year old drivers though?

Wait so I can run the Metro games on my CF 290's while using my GTX780 for PhysX? :eek:

Time to order up a 4K screen

Not sure why you picked me up, when I clearly said I feel it isn't fair and as for the sarcastic face

Because you started off well=nobody knows :cool:

, but then preceded to state AMD knocked it back not knowing what exactly transpired=nobody knows as there has NEVER been transparancy about the whole debacle, 'Nvidia claims' :rolleyes:

doesn't equate to gospel.

Gregster said:
AMD embrace everyone you say? What about their own 6 series users? What about their 5 series users? Why are they not able to use Mantle?

5 and 6 series don't stop working as advertised with Nvidia present, older gpu's use VLIW and not GCN to answer your point, not that it matters, your thread is about Nvidia disabling their own features if AMD is present, not 'why doesn't Mantle work on older architecture'-which has already been fully explained by AMD...

You missed the part-'Forward compatible' directly under 'not tied to GCN architecture' btw.

Which is basically your usual deflection defence retort in anything 'anti Nvidia'.

Your thread isn't about anything AMD enforce/support on their paying customers, it's about Nvidia enforcing disabled features on their own customers hardware, stay on target...

Wouldn't you like the option to run Nvidia/AMD and use all prop tech-if you choose to considering it's advertised features?

No where does Nvidia state PhysX gets disabled, there is no small print anywhere on/in the Nvidia boxes Iv'e held in my hands.

Or is it ok that one of them disable their own hardware and remove the choice completely from their paying customers?

PhysX 3.+ cannot be hacked btw, only>PhysX 2.+ can be hacked.

Ok back on track

Good news guys, it appears PhysX still works if you have a Matrox G200eH on board, I know many of us will be releaved to hear this

Everybody has agreed that this is a very bad move by Nvidia, even the staunchest of Nvidias supporters and yet we still find things to argue over.

You got to love the graphics card forum.

I lambasted nVidia for it and attempted to find a workaround (which works for some of the older PhysX cards) but seems I am responsible for nVidia and have to take the stick because of what they do.

Pathetic really.

Not really.

What AMD tech are you talking about?

Next question

The ball is firmly at Nvidia's feet on this topic-AMD has zero bearing on Nvidia feature restrictions.

If you didn't deflect or apportion blame for something AMD has zero involvement with in disabling features in competitors hardware and you won't get any stick.

Before I say this I want to stress that I think Nvidia should allow users to do hybrid PhysX, However I can see their argument:

Apple don't like people installing their O/S's on other peoples hardware even though the person has paid for that O/S, because that's not the way it was designed/intended to be used (their pair cheap software with expensive hardware so one offsets the other).

Likewise the idea that a person can combine a cheap Nvidia card with a high end AMD card and get the same performance as a high end Nvidia card* will obviously annoy Nvidia from a business standpoint, and we have to remember that Nvidia/AMD/Intel/Apple/etc are all businesses and are legally bound to act in their shareholders interests.

*Out of interest, why would people do this even if it was allowed? my CF 290 + GTX780 example is a bit odd as I already have the cards, but buying a 750Ti + R290X would be more expensive than just buying a 780Ti...

bru · 7 Aug 2014 at 12:05

So has anyone actually tried this with an AMD APU yet?

Just in case we are getting all hot and bothered over nothing.

Silent_Scone · 7 Aug 2014 at 12:05

Let's talk about tactlessly slapping your name on 2nd generation SSDs and aiming them at gamers, rather than pointing fingers because you're not able to use PhysX, because it's not owned by the vendor of your GPU.

You must live in a bubble some of you

So can I, I used to mind, but I can see their point, I'm not annoyed that Nvidia disable add in gpu's to run hybrid PhysX, but hybrid isn't the issue.

I'm annoyed that they won't let me render and use gpu PhysX solely through my 670(bubble wrapped by Nvidia mj

) while my 290X sits on desktop mode enforcing me to remove a £300+ gpu from the system and possibly now demanding apu's are disabled in order to run gpu PhysX with Nvidia hardware.

bru · 7 Aug 2014 at 12:48

Somebody here must have an AMD APU rig that they cant test an Nvidia card in to see if works or not?

Or we might be moaning about something that has been the case for a good few years now.( the only change I can see is the not working with APU's which we need to test.)

PhysX hasn't been disabled using apu's.

I checked myself after remembering my 9800gt would fit in my case where as the 670 was too big(small totally passive rig in the bedroom).

That's what(I'm guessing) has been discovered.

Damn, we need a new article talking **** to bash NVidia with now... I'm sure there are some AMD fanboy editors concocting something as we speak.

MooMoo444 · 11 Aug 2014 at 10:33

Oh, if it's one AMD and one nVidia card and it's disabled then no problem..

I read the topic title and was worried I wouldn't get PhysX on my 780 SLI as one is MSI and one is Palit

Ok cool, thank you for actually testing this and setting the debate to rest.

Yes it does kind of make the entire original article a complete waste of time.
Don't worry though I'm sure there will be another damming article soon enough.
