im going to go out on a limb here and say i think im going to respect john carmacks opinion on this issue .

So you think OpenGL is the "future" too? :hmm:

Every single GPU physx title here:

http://physxinfo.com/data/vreview.html

There are 15... BUT one of those games only uses gpu physx in a couple levels. So that is only .3 of a game, the other is a free tech demo game download from nvidia, so it's off the list.

13.3 Games in 5 years use gpu physx.



^^assume these smilies to represent me laughing at how ridiculous of a joke gpu physx has proven its self to be.

So PhysX hardware acceleration in 20 or so games during 5 years of existence makes it a success because other physics middleware don't have GPU acceleration?

Looking at the numbers, I can understand why everyone but Nvidia doesn't invest heavily in GPU physics. Doesn't seem to take off despite Nvidia pushing it whenever they get the chance, does it?

Wake me up when either Havok or Bullet physcis launches GPU accelerated games...otherwise you are claiming you won the race...by not running

it is in some spaces. OpenGL is lagging right now in the PC space, doesn't mean it will be forever.

but simple fact is, GPU's have high latency per thread, Ridged body physics needs low latency or the game itself needs to be very slow ( low target frame rates, high levels of blur etc). GPU's can't provide the performace of CPU's at the latency of CPU's and thats why 99.9% of everthing(game physics wise) is CPU based and most of the things that aren't are partical/cloth and other non game play/world space effecting things.

I have a pretty picture for that
Pretty picture, but it is not exactly correct - you've missed some PPU PhysX games (Infernal, Stoked Rider), added some non GPU PhysX games (Watchmen, Breach), etc.

To aid such disputes, we are planning to add section with statistical graphs, like in this article, but generated dynamically every day

Welcome to anandtech, love your videos

It can use either. There were 3 special maps released which showcase hardware PhysX in UT3, but the core game uses CPU PhysX only. The engine integrates PhysX so obviously it's available for anyone to use GPU acceleration, but most people don't.

Lonbjerg likes to flog the dead horse of PhysX being super popular, and acting like that has any meaning whatsoever when it comes to GPU PhysX.

I have a pretty picture for that.

I'm sure he'll tell me if I missed any games. (Games, not tech demos or benchmarks or in development titles.)

I havnt heard of a lot of those games. Like Switchball, Hot Dance Party, Watchman.

Metro2033 has GPU physx? Really? I turned "Advanced Physx" on and I didn't get a performance hit or any extra stuff on the 9600GT.

Some races aren't worth joining. It's like driving by the people all dressed up at the renaissance fair and saying to your buddies 'Yeah... gonna pass on that...'

But by all means carry on enjoying your 3 game releases a year, and hey 1 in 2 years there is a game actually worth playing.

Perhaps because it hardly uses any extra PhysX effects in GPU mode:

Great! There's another we can strike off the list folks. Down to 12.3 games now.

So AMD is not planning to race?

Sometimes the arguments here are worse than those from "Intelligent Design" people :thumbsup:


This is the wrong forum to discuss Intelligent Design.

Denigrating and stereotyping people based on their personal beliefs and ideology is not acceptable in the technical forums.

Does the word "hardly" mean anything else to you than the rest of the world?

Added effect = added effects...no matter how few or miniscule...

No nvidia is in a race with themselves and somehow managing to lose 12 games in 5 years

= BloatX

Are you illiterate? I'm starting to get the feeling that you can't read properly.


This manner of posting is counter-productive and inflammatory. Please do not post in this manner.

Locking this thread for the moment until I can sort out who needs infractions and vacations...wil re-open the thread once it has been cleaned up.

I am re-opening this thread. I expect people to be mature enough to handle themselves in a manner that is befitting a technical forum and adheres to our posted guidelines.

As a result of repeatedly demonstrating his inability to conduct himself with dignity while maintaining respect for his fellow forum colleagues, member Lonbjerg has earned himself an auto-vacation through the numerous personal attacks and member insults he chose to embed throughout this thread.

Lonbjerg's posts are to be viewed as an example of that which is completely unacceptable in terms of a combative, inflammatory and generally caustic posting style for this technical forum.

If you find yourself posting in a manner that is akin to his then you are likely headed towards earning infractions and, if you persist as he did, an auto-vacation.

I am re-opening this thread because despite the best efforts of some ill-behaving members there are a number of members who are engaging in productive debate and discourse and they should not be punished by having their opinions and voices stifled and censored as would be the net effect of locking this thread.

Excellent examples of how to deftly debate the technical merits of the contents of post can be seen in the civil and respectful point-counterpoint dialogue that transpired between Seero and aka1nas in posts 112, 119, and 160.

There are many more examples of such exemplary technical posting discourse throughout this thread.

Please conduct yourselves in a manner that is befitting a technical forum while enjoying the access you have here to your fellow forum colleagues whom collectively create a unique VC&G community here in these AnandTech Forums.

What I would like to see is a multi-platform, device, tool set that caters efficiently to any device to raise the bar, easy to use, so developers can implement more physic content to improve game-play, fidelity and realism. People may argue on how things should be done but will anyone argue that improving Physics isn't welcomed?

If a developer desires to use the CPU -- efficient and innovative tools and features to try to improve immersion for CPU's.

If a developer desires to use the GPU -- efficient and innovative tools and features to try to improve immersion for GPU's.

For a developer that ports titles -- efficient and innovative tools and features to add Physic content easier for multi-platforms, considering the strengths may differ.

Wow, I leave for 2 days and this is what becomes of my thread :/. Almost feel sorry for posting it at this point.

 

[DeathReborn]

Personally I think anything that improves gaming even if it is not taken up by competing HW manufacturers is a good thing. People may think PhysX doesn't improve anything but it gives developers more tools, more functions they can utilise.

Havok should have had a GPU component and nearly did until Intel bought Havok and tossed the idea out the window. If anyone is to blame for GPU Physics stagnating a bit it is Intel.
