I bought an RX 480 and I still have an r9 380, I was wondering if I could run the 380 as a physx card like how I know you can do with Nvidia. My friend runs a 980 ti as a gpu and his 750ti as a physx card
 
Didnt think so, closest thing I can think of was whatever display adapter mode is, either EMDA LDA or MDA
 
Nvidia PhysX effects can sometimes be enabled to run on the CPU for AMD users. Depends on the game though.
 
You used to be able to get away with running a nVIdia card in PhysX with AMD, but you can guess what happened to that lol.

But the CPU Physx support is crippled so it doesn't run very well. I had "lots of fun" finding this out with Borderlands the Pre-sequel. I ended up with Physx on High on my gaming PC (2x Radeon 280x) after it transferred the save from my notebook (with Nvidia graphics). It was slideshow-tastic, despite not loading the CPU very much. I didn't realize what was wrong right away, just noticed the game would slow down horribly during fights.
 
CPU PhysX has always been a disaster, part of why PlanetSide 2 didn't take off at first like it should have, everything was forced CPU without a way to disable it unless you had GPU PhysX.
 
AMD tried making its own physics types with OpenPhysics, Bulletphysics etc. But they failed.

PhysX runs on CUDA(Nvidia) and CPUs. Most PhysX implementations are actually CPU only. Even consoles use it.

AMD's GPU accelerated physics eventually migrated to DirectCompute; a Microsoft technology. Alien Isolation was a game with it implemented and ran equally as well on AMD and Nvidia hardware. The Linux port of the game was outsourced and ran like crap on AMD hardware though. AMD isn't known for Linux drivers, but lately they have been getting praised for them. Would be interesting to see if the game runs better now that they have actual Linux drivers or was it the outsourcing of the port.

PhysX has gone mostly CPU as you mentioned since Nvidia has no presence on consoles. On PC, GPU PhysX is mostly dead except for a few holdovers. The new VR Funhouse demo might have it; I didn't pay attention to it enough to care. One of the newer games with GPU PhysX implemented was Batman Arkham Knight and is a shining example of the implementation. Killing Floor 2 has the new FLEX system; not sure if it is hybrid CPU / GPU or all GPU. I tried the demo with my gaming clan and it ran like crap on my system and their's. They all have shiny new Intel systems and Nvidia GPUs. So we voted to skip the title due to it running badly. Some of those guys have thousands of hours in the first Killing Floor and were so stoked for the sequel. Oh well. ;)

Here is a list of game with GPU PhysX. When I look at this list in context to the 2,700+ titles in my Steam library alone; I tend to think of PhysX as only an afterthought. Well I tend to skip PhysX titles until they are well patched. After they have been patched for at least 6 months to a year, they will run pretty good. That's my experience with them.
 
If you look for it you can find some drivers that have been patched to work with AMD Nvidia setup in same machine. This was a good while ago. Nvidia does not support this configuration.
Physx is nothing but proprietary crap the cpu version uses legacy x87 code ...


PhysX: an easy target ?

Every DX12 title that supports multiple gpu could work on your machine. Not to sure about the scaling , the only game that might work is Ashes of The singularity (google it see if someone already tried it with RX 480 and 380)
 
If you see the TWIMTBP nvidia logo... or whatever, you know it´s been gimped. At least UT3 is easy enough to run on my current HW.
 
Started up Mafia 2 thinking PhysX GPU wise would be worth while. Made sure driver was selected to use the 1070 for PhysX. Selected PhysX in the game on high and did benchmark - Pure crap - avg frame rate was in the 30's :mad:. Went to medium physX and not much better :eggface:. Turned off physX and game was like 200fps. What pos is this? Am I doing something wrong? I just reloaded the game from Steam, not as if the game was already installed. It is acting like it is using the cpu (all one thread or is it?).

Then again looking at the effects was more of a joke then anything else - amazing what one bullet can do to a wall! Tons of oddball debrie rains forth like an explosion covering the floor. I can see why PhysX never really took off - the effects are just limp stick and not really part of anything.
 
PhysX is the very thing that made me start to really dislike nvidia because even when it works its pure SHIT. Actually when they disabled gpu physx when any AMD card was detected (And i never even owned AMD) was the first straw. I have seen all kinds of cpu based physic that blows away Nvidia proprietary effects anyway. It was like the very beginning of Nvidia "Gimp Works" !

I would say something is wrong yes. If my memory serves me correct Mafia II uses an older implementation and requires the legacy drivers.
 
I really hadn't thought PhysX was much of a thing for over a decade now.

I used to have a dedicated PhysX card long ago, but DX-12 has been ranted about for years now also and it's just another "we'll see" thing atm.

I'd think it will be a much larger impact than PhysX, of course.

Actually AMD cards have done physics for a very long time. They purchased the rights to the HAVOK Physics engine long long ago.

Havok isn't the same thing as PhysX. PhysX is a proprietary driver from Nvidia for use on Nvidia cards. It is possible to download PhysX drivers and use the CPU to render PhysX effects in some games but the AMD card in and of itself cannot run the PhysX driver.

Ok maybe I will check into that but the incentive is kinda weak due to what I see is almost not worth it. I will try Batman games out next.

The batman games are probably the best showcases of dedicated Physx. The thing to keep in mind is nvidia is moving away from physx to gameworks which does not use a second card as a dedicated gameworks card. Gameworks and physx compatibility has been one of the biggest things keeping m using nvidia cards, in the games that use them well it makes a difference visually.
 
So Nvidia will no longer support PhysX? I guess the writing was on the wall for awhile with that. Well since I've havn't played any Batman games yet, should be a real treat with PhysX. That is if it works.

It is supported, what I mean they are moving away from the idea of using a dedicated card for hardware accelerated effects, GPU are getting so powerful that one gpu now is usually good enough to do it all.
 
With Async Compute, even Nvidia method I do see that is probably smart to do for a more efficient use of all GPU's. Ok that is good then, just wished it was more open standards so developers could have a single solution that just works across the board with consoles, pc's (Intel, Nvidia, AMD graphics).

Actually it was a hardware and software physics platform designed by Ageia semiconductor company. However it was just a alternat way to apply physics to games. Like making hair move right ot flags move right. Which the havoc physics engine also does. Try again

Microsoft owns Havok not AMD

Yea that is now correct. However Amd has had a contract with Havoc for a very long time even when Intel owned Havoc. Havoc physics have been customized for better application on AMD video cards since 2008. So while you are correct about Microsoft having bought Havoc. Amd still extensivly uses Havoc.

Havok is a physics software that is hardware agnostic, always has been, so it makes no difference if you have a nvidia card or a Radeon card.

AMD optimized for Havoc, Nvidia didn't. However you made my point for me the proprietary nature of Physx always made it a failure instantly from day one. Havoc is king.

As much as I would like to agree, and I definitely do in regards to Nvidia PhysX, I thought that after Intel acquired it, it kinda died or at least wasn't getting much use or updates. Again that is what was being said but that could have been Nvidia fanbois downplaying .

as far as technically ability PhysX is definitely superior, proprietary does not doom something lack of implementation does. Nvidia has shifted physx into gameworks so it is still being used and not dead.

Nothing on their site, no press releases, news etc. from 2016. So what is going on there? I was looking for GPU compute support in the future but nothing.

Yea Microsoft internalized all the information and just isn't updating the page anymore.
 
All I know is that NVIDIA acquired AGEIA about a year and a half after the launch of their oldest cards that were Physx capable launched. February 2008 for purchase vs the 8800 coming out late 2006. The 8800 would have been in development for well over a year before that, so Nvidia had already designed that chip by early/mid 2006.

This means it's likely just a segment of code that NVIDIA doesn't want to give out for free or to be open sourced, as opposed to a hardware requirement that's super special.

There has never been anything stopping Physx from being universally accepted other than NVIDIA's inability to share its toys.

I tried Isolation on Linux Mint 17.2 with my 280X and the 15.12 AMD drivers and the game ran really smooth. I don't have any benchmarks, just an anecdotal notion, but it was more than playable and almost equal to the Windows version from what I played of it.
