No NVIDIA GPU PhysX if non-NVIDIA graphics is present

[BeastlyCarrot]

NVIDIA GPU PhysX acceleration is not available if there is a non-NVIDIA graphics 

processor in the system, even if it is not used for rendering

Sorry, ment to say: No NVIDIA GPU PhysX acceleration if non-NVIDIA graphics is present in the title...

LOL Isn't that what they already di- shit I forgot PhysX on CPU was a thing...

[MrAlexOneill]

Does this mean that PhysX will not be allowed on amd gpu's? I mean, it sucks on amd gpu's but to know that it is still there is nice.

It never was allowed. The thing was that they would be processed on the CPU which sucked BIG TIME and it seems like they will remove the feature entirely. It doesn't really matter, as PhysX with an AMD gpu was completely useless anyways.

Isn't physx single threaded for cpus?

Yes however the processing of it either way sucked.

PhysX is a collection of CUDA code that nVidia release to game developer, that's the reason it doesn't run on AMD hardware.

Previously you could run an AMD Graphics card as your primary rendering card and have a secondary NVIDIA card for PhysX processing, this will no longer be possible, although it wasn't an optimal solution to begin with...

It wasn't possible for a LONG time buddy. It was in a driver update like a year ago if I recall correctly.

Guess I am wrongly informed then, thx for the heads up

IIMO nVidia doesn't want to support it that's why they don't allow it.

[Crion]

Old news.  Nvidia hasn't allowed this for a long time.  Besides, everyone kinda figured this would be the case when Nvidia bought Ageia back in 2008.

This does not stop CPU Physx so the only people affected are those who:

 

1) have this driver and potentially every driver henceforth

 

2) have both Nvidia and AMD cards in the same system as in Linus' recent SLI/CFX video

[Ertman]

Well it's a nice-ish feature, it's not super necessary. I never got why Nvidia has done this type of thing.

[bcredeur97]

yay i can see sparks flying off my bullets.

 

 

big deal.

 

/sarcasm. Yes i know it does more than that.. but I still dont see it being a reason to switch to Nvidia.

Actually, I thought someone made 3rd-party drivers: HybridPhysX to make it "work". But, it's only compatible up to PhysX 2.0. NVidia have, for a while, disabled their cards if a non-Nvidia card was the main GPU.
