PhysX, on every modern implementation, just runs on the CPU. If using an Nvidia GPU you can designate it for PhysX, but I don't believe that this actually gets used.
So basically it does the same on amd as it does Nvidia, even with my SLI setup, still seems to run off my cpu. Can you still see the physx effects tho?? Like bl2?
meaning it will not be part of your SLI setup, it will by your dedicated PhysX card...
Meaning, if you want SLI & PhysX, I believe you need to run a third Nvida GPU...?
FTFYWant to enable PhysX [on 2 games that came out 10 years ago]? Get Nvidia.
Yes its open source and AMD could support it in their GPUs if they wanted. They don'tI've been reading alot into upgrading gpu.. seen that physx is a open source now and can be used on AMD cards and have the physx effects?
Can anyone confirm this for me?
This is a fair point.Yes its open source and AMD could support it in their GPUs if they wanted. They don't
That said, at this point Physx can be done on the CPU without much performance hit, so you don't really earn much by using GPU Physx
It's hilarious, PhysX came along right when CPUs starting going all multicore and suddenly we had spare cores with nothing to do. Except for running things like PhysX.
Most PhysX is CPU based, only a few games do GPU PhysX.if you are running it on the cpu is it still tecnhical PhysX ?
I believe it is just physics calculation but not PhysX
Just like creative made mp3 players and not Ipods
PhysX is a brand name covering a specific set of commands/methods to do physics calculation
Physics calculations is the task of calculating physics. it seems like ppl interchange brand names with definition words
aka you can do PhysX on a GPU and you can do physics calculations a different way on the GPU but its not PhysX.

It is an extension.
I credit you as a guy who is well read on computer tech yet you are asking the most basic of questions about an old technology when you have the internet in front of you.if you are running it on the cpu is it still tecnhical PhysX ?

I did expect better.
My last post spelled it out.
to be fair the original physX api was cpu multi-threaded until nvidia bought it then it was capped at single thread when not being used on a nvidia gpu.
Sorry Sven, it was a bad day yesterday.Asking is how you get information. its what a forum is made for.
When a person is putting out information that goes again your current information asking into it is considered proper way imho.
The fact that i accept the limitations of my knowledge and seek to add onto it, I see that as a good trait of mine.
Unlike what most people will do: is argue with a closed mind and bring up made-up theories and arguments with no grounds in real world facts. As an examples just see the Series Sam thread where a person constantly claimed that using procedures generation methods, would mean everything would be random. This was despite several explanations to him that was not the case.
You reused the terms when the issue was in regards to the terms used. So reusing the terms without defining them is not helping the question on whatever the terms where used correctly.
You answer did not resolved the issue on defining the terms.
People tend to use PhysX to cover non-PhysX physics calculations as well
Just like people missuses the words Kleenex or ipod, for tissue paper and mp3 players.
That was what my question was based on
Looking back at you answer. Could your answer on itself logically work with exchanging Physics with PhysX? Yes, it would still be a valid answer. So it did not help on the issue of the misuse of the word PhysX, as you answer itself could potential be affected by the same issue.
anyway I managed to read up on it myself, When I got home from work
Requires CUDA 10.0 compatible display driver and CUDA ARCH 3.0 compatible GPU
CUDA acceleration is only available on NVidia GPUs.If you look at the PhysX https://github.com/NVIDIAGameWorks/PhysX
it says
"
Requirements:
"
- Python 2.7.6 or later
- CMake 3.12 or later
No where does it state you need a GPU or nvidia GPU for that matter. It also has a part about having Hardware acceleration

- Requires CUDA 10.0 compatible display driver and CUDA ARCH 3.0 compatible GPU
It also says it works on iphones, android, linux whatever. If i were to make a jenga game using say unity game engine that has out of the box PhysX support i can make ports to android, PC, iOS, PS4,..... pretty much anything else, and it will run the same way. it's just an API,
CUDA acceleration is only available on NVidia GPUs.
In theory it could be licensed for use by Intel, AMD ... drivers, but they havent so it is NVidia only.
ps you are reading the requirements for the SDK.
The use of PhysX does not need Python or CMake for code that is already compiled.
Side note.. single gtx 980 work over 770 2gb sli? Can get one for about 100$
Um, no. There is a huge difference between 1080p and 4K, maybe you never saw a good setup.Thanks, But i dont play at 4k.. cant really see a diff between 1080 and 4k. NO ONE CAN, Its more than human eyes can see

Could I get a rx 580 and use my old gtx 570 for dedicated physx?
