FYI - Batman demo to download with PhysX...

[Talonman]

Your welcome.

I think that the PhysX effects adds to the game.

[trinibwoy]

Yeah, while it's not really that impressive overall it's a bit better in-game than it looks on the video comparisons. I thought the leaves in Darkest of Days looked pretty dumb at first but after playing the demo it does give you a sense that wind is blowing around you, something that you don't really experience in a game. It's only a matter of time before some developer does something really cool with the tech.

[Minstadave]

Surely there's nothing there that can't be done easily on a CPU, its almost as if they've taken effects out of the standard version just to make Nvidia happy.

thats what im thinking. and i cant blame them if nvidia gave them some kind of contract to go with the money for physx additions

[blaxtr3m3]

I think its fair, since they made a lot of effort to get PhysX to this level and to give something back to their loyal customers.

They have not given you anything in that game that you could not of had without PhysX.
So they have put allot of effort to get PhysX to a level that it gets used in away that could already be done with other techniques.
A solution to a problem that does not exist so they make a problem so that they can fix it.

Ill be right back just after i reinvent the wheel.

[Talonman]

Just make sure it's a much slower wheel that takes your CPU resources, so your analogy fits...

Maybe we could put all GPU work on the CPU too, so we wouldn't even need a GPU any longer?

[Manicdan]

if the game is being gpu limited, maybe it would be smarter to move it to the cpu, but doubt the cpu could handle as many physics based objects.

whats the framerate with physx on vs. off? can someone test this on the demo?

nice links, the funny part is my laptop is getting framerate issue from trying to decode the HD videos, it might be better if i were to just run the demos, lol.

Rest assured I will check them out when I get home tonight.

I want to see what they are trying to say...

If we ever want to have a PhysX drag race, CPU -vs- GPU, count me in.

I buy into the Nvidia perspective that we should let the CPU do what it does best, and let GPU's do what they do best.

What the GPU does best is render.
My point is not what can do it the faster but using what is available to get the job done & not limit it to ether for the sake of it.

An i7 could playback my MP3 music & MPG movies faster than my AMD955 but its not required because my AMD955 is capable of playing them at the intended speed as it is.

With all the talk about OpenCL and Snow Leopard together and how the spec will allow Apple's upcoming hotness to exploit graphics accelerators, it's easy to lose track of the place where the standard could make its biggest impact: gaming. Yes, OpenGL may have lost favor in that realm in recent years, but OpenCL looks to captivate the hearts and GPUs of gamers everywhere by applying some much-needed standardization to the physics acceleration realm, first shown in public at GDC running on some AMD hardware. Havok is demonstrating its Havok Cloth and Havoc Destruction engines, the former of which is embedded below, and we think you'll agree it's quite impressive. OpenCL allows such acceleration to switch between the GPU and CPU seamlessly and as needed depending on which is more available, hopefully opening the door to physics acceleration that actually affects gameplay and doesn't just exist to make you say, "Whoa."

[Talonman]

As long as it's on the GPU via OpenCL or CUDA, I am on board with that. I only disagree when I get the impression that people think everything should be run off of the CPU, in the name of standardization.

To me, standardization is only a good thing if it dosent come at the cost of performance. When we are talking about any physics engine, I believe the GPU is better suited to run that.

I don't see people saying that everything should be run off the CPU, what i see are people saying that what they have seen in some games could of been run on the CPU.
PhysX is the exact mirror of your comment with everything should be run off the GPU even if it does not need to.

No one said that the GPU is not better suited but it should not be mandatory for physics that can be done on the CPU.

[Talonman]

Do you think they will feel the same way when ATI has a rockin physics engine, and a new game comes out, and the developer opted to run it on your CPU insted of your faster ATI card(s)?

My guess is at that time, they would rather have the physics workload, no matter large or small it is, to be processed off their GPU.

I still think some Nvidia animosity is the force behind most comments.

I see things like, 'looks like the developers went for the Nvidia cash'.

It might be they just wanted the best performance they could get for their new baby? If that ment using the GPU, so be it.

The developer will use what is best suited for the game in question on the GPU or CPU or BOTH & the possible option for the user to decide with ingame options just like in game gfx & detail option instead of the being denied to use the physics at all if you don't have a specific vendor gfx card.

[Talonman]

Hopefully that will be taken care of soon with OpenCL.

I do want ATI and Nvidia both to run physics well. It would be good for game development and resolve any bad feelings.

More often its my gfx cards that gets maxed out just doing the gfx, my first option would be to see how the CPU gets on if given the option depending on the game.

[Talonman]

For me I worry about my Q6600 getting too much work, with a 295 and 280 standing ready to serve.

[Talonman]

http://www.nvidia.com/object/physx_9.09.0814_whql.html

FYI - I gave that new PhysX a test out on Batman.

System:
Q6600@ 3.81GHz Driver 190.38
(1) 295 processing Graphics set to 621/1458/1188
(1) 280 operating in dedicated PhysX mode set to 756/1512/1269
Ambient Occlusion was set to on in the Nvidia Control Panel.

Performance with the PhysX that came with 190.38
Game settings:



46 FPS


42 FPS


50 FPS


52 FPS


46 FPS

Note that 52 FPS was the fastest I was getting.

I installed the new PhysX...

60 FPS


60 FPS


61 FPS


60 FPS


60 FPS

I did realize a performance increase... Getting 60 and 61 FPS.

I would say it works!

Talonman (or whatever your user name is) your information isn't accurate because the CPU isn't be utilized as intended for this game. It becomes a specious claim when certain physics features aren't seen when physx isn't used (ie CPU), etc. Something already mentioned more then once in this thread.

[Talonman]

Thanks for the input, but none the less, my game is running faster after the install. (PhysX or not)
I used the same system and game settings for both.

Maybe another member could test this also.
