Correct. It's CPU-only.So the game has no HW accelerated physx component?
If it ever approaches the more impressive and game-changing physics seen on the CPU without a performance hit, or if it manages to exceed them in an impressive way to justify its current performance hit; it will be worth taking notice of.
In its current state nvidia should be paying us to use it while they try to make it work, rather than the other way around.
It just tanks performance to the point it would not be feasible. The heaviest implementation I've seen of gpu physx was in Mafia 2 and Apex High was a huge performance hit for effects that didn't approach, again, physics done in other titles and better.
You keep saying this and I already tried to point it out (but my post was mysteriously deleted), but on my system performance was still superb with physx on high and all other settings (except in-game AA) maxed out. You may have a strong opinion with your beliefs and position, but making statements that are deceptive or wrong don't help your cause. If there is ample power left over for the GPU to do other things to improve the gaming experience, it doesn't really matter if the frame rate goes from 125fps to 65fps, it would be impossible to tell in game.
I also ran the benchmark on my laptop (2620 i7, gtx560m) and it still scored a respectable low 40's with physx and all other settings on high (except ambient occlusion and AA) @ 1080p.
Canned benchmark is not indicative of what gameplay was like. There are large slowdowns when the ridiculous rock chunks and glass shards start spraying all over the place...
And again, why should I give up any performance when the CPU physics does not have that same performance hit and the gpu physx is not offering an experience as immersive and game-changing as the CPU physics does.

sorry but I do not believe you. the benchmark for many games will look great when you see the averages but in actual gameplay there are some very noticeable slowdowns just like Grooveriding.Weird, I experienced absolutely no slowdowns at all when playing the game on my gtx560ti. In fact, the "canned" benchmark is more demanding than nearly all situations in the game.
sorry but I do not believe you
and I own the games too. it takes a few seconds of searching to see my comments being backed up by others. its well known about modding the clothing in Mafia 2 because it tanks performance in spots. its well known that the Scarecrow levels will tank performance in Batman. those are facts about actual gamepaly that your flyby benchmarks do not show. you really need a very good dedicated card for physx or that's what will happen.FWIW, the fire scene in Mafia II is the most demanding scene in the entire game and that constitutes 1/4 of the benchmark, but that probably won't matter to you. You pretty much said the same thing to me after I posted benchmarks of my old gtx465 overclocked. http://forums.anandtech.com/showthread.php?t=2106374&highlight= Believe what you want I don't think I have to continually prove myself to you over and over again.
no. you can use physx and graphics on your single Nvidia gpu. the point was that the benchmarks will make everything seem rosy while actual gameplay will be sluggish in spots.Without a dedicated PhysX card, the cloth physics is done by the CPU in Mafia 2, I believe.

nVidia said:Clothing is running on CPU unless you have a GPU, fully dedicated to PhysX.

for instance I can get about 100 fps in the Batman benchmark with all very high settings and high physx but I will get very noticeable slow down during Scarecrow levels for sure. same thing goes for Mafia 2 where you have to mod the game or its too choppy in spots because of the clothing physx. heck even the minuscule effects in Metro 2033 will slow down things a bit and severally cut into the minimum framerate yet the average in the benchmark looks great.
where are you getting that from because I have never heard of that?I understand that but with Mafia 2, using a single GPU for rendering and PhysX, the cloth physics are done on the CPU. Using a dedicated GPU for physx, the cloth physics are done with hardware PhysX.
well that goes to show how crappy the implementation can be which is one of the things I have been complaining about. you have to mod the freaking game for it to run smoothly. so again I still say physx is nothing but a joke.Edited my post above that offer links.

Don't misunderstand, I'm not saying physx is a bad thing. But for some other games the performance hit for hardware physx is huge -- the two that come to mind are metro 2033 and batman: AA. Although the latter is hardly noticeable since the game runs at 200 fps otherwise.

so to you 30fps or less for some effects that you cannot even really notice is respectable? yeah physx is wonderful...You are on a roll today. How is it a crappy implementation? The game was setup to shift the clothing onto a dedicated physx card or to be pushed onto the CPU if a dedicated card is not present. It's utilizing all 4 cores on a quadcore CPU and doing a respectable job:

The performance hit with physx on in Metro2033 was minimal. That game is extremely demanding with our without physx enabled.
so to you 30fps or less for some effects that you cannot even really notice is respectable? yeah physx is wonderful...
and that's the benchmark which is not reflective of actual game in spots. I tested this crap too a while back. my minimum framerate was 20-25 fps higher with physx off then with it on. there are plenty of places where I would drop into the upper 20s with physx on in that game. with it off I rarely dropped out of the mid 50s for a minimum. so again you can keep defending physx all you want but many people like me think its a joke for the actual performance hit that you get at times.Full physx on with my system: 56 fps average
Clothing disabled except on Vito: 67 fps average
Yeah I'd say it's doing a respectable job, the game is running close to 60fps with all graphical options (except in-game AA) turned on. And again, the benchmark is significantly more demanding than playing the game. There are never that many explosions on screen at once, and the fire scene itself is the most demanding scene in the entire game.
Do yourself (and the internet) a favor and just turn it off for all the games you do own and/or will purchase in the future that have gpu-physx as an option. I know you like to complain or have negative views about nearly everything on these forums, and you have an especially hard time accepting other people's experiences, but at least it would be one less thing for you to complain about.
Uh, what? I've fiddled with it myself , its definitely not minimal. Do you have the game?
On a single GTX 580, medium quality/DX11/tessellation on/advanced physx off it runs very smooth with framerates ranging from 55-150 (most of the game is indoors). Adding phsyx to the mix instantly drops my framerates by about 20 on average (I usually have FRAPS running)
Again, I don't think physx is a bad thing. My experience however has been that there is a performance hit for using it , but in many cases it doesn't matter (batman: AA)
