Physx is it used much ?

Read my post above - GPU accelerated effects cannot be ran on the CPU. As I said, what difference they make to IQ is a different question. One I'm not really that interested in personally.

It's up to game devs to implement features if they wish.

Does Batman AC have GPU accelerated effects? what effects should or shouldn't I be seeing?
Because all I seeing is the same as what Nvidia are showing in the trailer. just running at 30fps and not 60fps
 
Who'd have thought this thread would go pear shaped? :p

@OP, Physx is something you'd have to try, see if you like it, then go from there. No amount of 'its pointless' or 'its great' is going to help you out. If you don't use it, IMO your not missing out on that much, but who knows you may really like it?

Oh and welcome to OcUK where opinions are forced down your throat as fact :)

Surely that is a question you should be answering as you're the one saying that you're running GPU accelerated effects on your CPU :p.
 
Actually I think theres quit a few games including Arkham city where the game does allow you to see all the physx effects that the gpu does. They just run terrible in comparison to the gpu. I remember and think it was one of the batman games that were tested where they hacked the code to allow the cpu to run on more than one core making the amd setup fasterin some cases. Maybe it was metro cant remember fully. I think in more recent games like origins amd users dont have the option available to run the high mode.

It is Metro, Metro 2033, it will run all 6 of my cores with advanced PhysX, the performance is perfectly acceptable.

It's not possible to see GPU accelerated effects without a nVidia GPU... It's not me saying it, that's just the way it is.

But why am I seeing it then??? lol Smoke moves when walked through. Fire sparks roll on floor. Extra effect from the gun when hitting walls and floor.

Am seeing it all, i'll ask again why is this? I see everything that the PhysX trailer shows in my own test I get the same thing only with less performance.

As far as I am aware anything physics that can be done on the gpu can be run on the cpu. The gpu is just more effecient at doing so.

1+
Hence the reason for my worst performance but still playable at least on Metro and Batman.

Please go and read about it. PhsyX effects not necessarily equal to GPU accelerated PhysX effects. It all depends what the developer implements. You'd save yourself a lot of time by listening to what I'm saying (and Tommybhoy before me).

Only if the game designers choose to do so. This has not always happened as there are games where theres no difference in visuals just performance.

Then they aren't GPU accelerated effects. D'oh :p.

Shanks is basically saying he is seeing all the effects gpu accelerated or not. That was his whole point lol. There has been reviews on this for years with benchmarks. You can benchmark anything unless its equal effects or settings as yhats useless.
 




Performing these benchmarks with a powerful main graphics card and a dedicated PhysX card was a deliberate choice, given that a single Nvidia card normally suffers from some performance penalties with GPU-based PhysX enabled. Things would get quite bad in this already-GPU-constrained game. In this case, the difference between CPU-based PhysX on a fast six-core processor with well-implemented multi-threading and a single GPU is almost zero.

Its just a shame most other Nvidia PhysX games don't run full PhysX on the CPU let alone properly threaded like Metro 2033 did.

How does he know whether they're GPU accelerated or not? He doesn't have a point.

Yeah there's no doubt that PhysX is not very efficient but we are where are. :(
