Physx on an AMD card not cpu?

[MrMDAN47]

Hey LTT, I know this question has been asked a million times already but I wanted to know if there is anything new and I wanted the up to date answer.  So I know that Physx is built to run on nvidia cards only, and when you run it with an AMD card it only runs on the CPU, Thus killing your frames...  

 

I was wondering if there was any drivers, or software, or a version of Physx, that has come out that allows Physx to run from an AMD card and NOT the CPU.  Something that tricks Physx into thinking that the GPU it is running off of is a compatible one.  I am asking this for games like Borderlands 2, Metro Last Light, and others that don't come to mind instantly.

 

Oh and by the way when someone else looks at this post I want them to be well informed.  So please say something helpful.

NO.

Once upon a time you could use an AMD GPU and a dedicated Nvidia card for PhysX but now you can't. IIRC Nvidia cards have special shit in em that give them the capability to do PhysX shit

Physx is a nvidia feature, because they encorperate the capacity to drive it on their gpus, instead of cpus. If you don't have a nvidia gpu, then physx will always default to the cpu, since about 2014 there is no way to change this.

 

You used to be able to run a physx processor in your system, I.E. a low power nvidia card, and still use an AMD card for your main rendering, but in mid 2014 nvidia changed their drivers to literally abort whenever they detect an instance of catalyst in the background. Thanks nvidia for making people who would have bought your stuff, now not buy it at all.

that's aside the point though. No you cannot hack drivers to run physx on an amd card, it would brick your card, because that's all done in bios, not drivers more or less. the support for physx calc comes in on the actual hardware, because that's how nvidia like doing things.

It is a physical chip (or at least used to be and now may be built into the gpu, not sure)

You also used to be able to buy just a physX card to compliment your GPU waaay back in the day. Sadly at this time there is no way to run hardware accelerated physX with AMD cards.

It's called coding for what you have. AMD and Nvidia cards may produce the same end result, but do it in different ways. What works on one doesn't necessarily mean it'll work 1:1 with the other.

well i wasn't too far off

Ah..

 

 

Back in the days of AGEIA / NovodeX, you could, but when nVidia decided to make it "on the GPU" technology, it has been a "feature" of nVidia cards only.

...So if you are just going to post something like "nope" please go away, those type of replies are just uneducated and barbaric, I want inelegant answers only please.

 

You might want to re-read that last bit before one of the hundreds of potential jokes start showing up in rapid succession

FUDGE! thanks.

Thanks for the answer.  That really sucks that it is so deep as BIOS, It would be easier just to get an nvidia card if I have to go that far to get it to work.

That's still not quite how I would put it... pretty sure "nope" is actually correct, so not uneducated, and is hardly "barbaric"... I would say something like "unhelpful", but to each their own

Virtually no games use physx as a real big feature. Don't bank an entire purchase solely on that. Just get the more powerful  card for your budget, if it nvidia awesome, if its amd, awesome.

It's not BIOS, IIRC it's because PhysX is built for CUDA which is obviously only in Nvidia tech.

Shame they cut being able to use both together, but weren't there a few issues with doing that? Nothing they couldn't fix, probably, but still

True. While I love the various nvidia features out there (like physx) I don't know of any game that requires them - it would be suicidal to make a major game for just one brand of cards; you'd lose half the market.  The very fact that games with physx allow it to be turned off and are able to be run on AMD cards at all are proof of this.  I know in Borderlands, if you turn physx on you can't stand on flapping tarps since they can tear and blow in the wind, where as with it off you can walk on them, but that's the most significant difference ever I'm aware of.  Usually it is included simply for visual effect.

Yes, issues like fewer people buying high end nvidia cards

no!

Well not entirely. If people are running hybrid PhysX and are having issues that are pretty breaking it'll give the tech (And by extension Nvidia) a bad rep

IMO PhysX is pretty pointless, not a feature that should tip the scales on a purchase, so few games actually support it and how good it looks is hit and miss (Planetside when it supported it looked damn good with the sparks)

Oh I wasn't going to, if anything I'm going to buy another r9 290 and crossfire them. And deal with the nvidia only stuff I'm locked out of.  I was just saying if it's that hard to try to get Physx to work on AMD then I'll just forget it.

[MrMDAN47]

Well thanks everyone for your replies!  I'll go and overclock my 8350 now...
