Is Nvidia PhysX GPU acceleration necessary?

What is really the whole point to it?
Does it increase performance in non physx games?
Does it show extra effects in non physx games?

Is there a reason gpu acceleration should be enable on your card, ?????????

Just trying to see what is the point, because i have played about 3 games thus far , that is not physx games btw and i don't see anything different.
Even when playing games like Infernal, you can still see all the eye candy and effects even when using a radeon card.

All in all, it doesnt affect non-physx games

 

Meaning if you happen to play one of the 5-10 popular titles which use PhysX then you'll see moving/tearing cloth + more dirt/debris. This is about the extent of PhysX "acceleration", it's more hype than anything.

 

Personally, i think with PhysX off, non-PhysX games seem to work better. Then again, the only PhysX game if have is Mirror's Edge, and only works, albeit not quite so, under windows 7, which seems to kill the FPS on all the games i've installed on it so far.

 

I've seen poor framerate in WarHead when enabled.

So make sure, if you don't play any PhysX enhanced game to disable them in your NvCP or just don't install them.....

 

I think Nvidia needs to remove the software from their driver installs and let us decide for ourselves without having to extract them and remove it first. Its got its own download location so why pack them together??

 

Probably a psychological affect. When I see the driver description and see stuff like "optimized for blah blah new feature for blah etc" I feel "I would very much like to try that out." Marketing gimmick that will work on some

 

yea i have notice worse performance with gpu acceleration on. It is a interesting tool indeed, but yea more hype then anything.

peace

 

Nvidia PhysX driver is a software that enables various Physics effects through Nvidia Cuda enabled GPU's , in games that use PhysX engine for Physics effects. Thats what it does. Nothing else. ( tho ofoucrse there are still alot of games that use PhysX engine, but still run physics effects in just software mode, through the CPU ).
With GPU PhysX enabled, GPU increases the PhysX processing performance. ( ofcourse it requires powerful GPU, so that by doing PhysX effects, GPU still has the power for doing the graphics rendering ). In your case " the general", I would not recommend using your GPU for Physics processing. Thou you probably wouldn't have to worry about it, since your system is below the minimum requirements of any PhysX enabled game. So, with or without PhysX enabled you wouldn't be able to run those games anyway.

 

the general.. please tell me you have upgraded your PC.. your still running that old beast. its time to upgrade man just take your PC out and :biggun: it

I gotta agree with Richie here. I know we're in a recession and all so don't think I'm dogging your setup, but I'm surprised if you'd see any performance increase even in PhysX enabled games with your current config... For the sake of your rig I'd just turn it off regardless.

 

That's bogus. Unless a game uses GPU PhysX, the driver/GPU performance are unaffected. You can leave the GPU PhysX option on all the time and it won't make a bit of difference in non GPU-PhysX games

 

+1000

I've been whining about that for ages....

 

I think this sums it up. Also due to the fact that if you are running a single GPU like most do, to get that moving cloth, and a bit more dirt you will be sacrificing FPS.

Basically Physx can't be used to do major elements of the game. Because if it does then the game can pretty much only be played on systems with PhysX acceleration as the software PhysX is too slow. So whilst the majority of systems out there dont have PhysX, the game developers cant apply PhysX to anything more than additional visual gloss. Nothing that effects the gameplay.

 

Wait...Age of Empires III but...only the Mac version? What's that about?

 

Exactly...so don't disagree. Where it is simple that physx does get used, it doesn't matter if it is software or hardware. But it can not be used for anything CORE to the game that requires acceleration, otherwise the game starts to exclude non-Physx accelerated hardware, which they can't afford to do.

Seeing as for the next couple of years, physx hardware acceleration can not become mainstream i.e. over 80% penetration, it will NEVER do anything more than eye candy. Ergo, only relevant if you want a little more fluff in your scenes.
