PhysX

[Grimes]

 

IIRC there was such a hack for GRAW2, and it ran at a crawl.

 

I also remember reading a review of PhysX usage within GRAW. In single player the framerate was much lower as there were more objects in need to be rendered. However the big issue was in online play between players who have it enabled vs those who don't. It was something about how explosive debris could actually kill a player. I forget exactly what it was but I'm pretty sure it was something to do with a disadvantage to using it. The Physx enabled player could be killed by debris (all explosions on their system had it)where the non-enabled player couldn't, as their system wasn't rendering the exess debris.

Well I was refering to a hack that allowed you to run the PhysX without the PPU. And it was horrible.

 

Now it is true about frames being lower, but I believe there are reviews out with the PhysX on the nVidia chip and FPS is actually higher.

 

I cant wait until I get home to actually install this and checkout GRAW2 with PhysX.

[Prophet]

Its from FUD.

 

It could be that since the GPU is so much faster at the calculations that it needs the CPU to feed the data to it faster. If what they claim has any merit, than the PhysX would be done faster with a faster processor.

 

But again, its FUD.

Anyone can try it now. NVIDIA drivers now comes with PhysX included.

 

EDIT: on series 9 and up cards. Series 8 cards will be added later.

GeForce ForceWare 177.89 XP 32-bit

included NVIDIA PhysX System driver 8.08.01.

"Finally, the new PhysX System Software is here and should work with most GeForce 8, 9 and GTX 200 series cards."

 

This drivers works with my 8600GT card.

 

I test with the PhysX System driver demo programs and work it.

Yes say software, but in oficial web of nvidia say hardware.

I test with 8800 GTX and work.

 

For download.

http://www.nvidia.com/content/forcewithin/us/download.asp

 

Only need first option, others is optional.

 

Note: If you have installed a previous version of the drivers ageia PhysX, it is advisable to remove the old, before installing new ones.

 

The programme Nvidia PhysX propierties tell you that we have no Nvidia PhysX processor installed, which is true, but in Settings, you will come three options, one GeForce PhysX, which must be checked, and that is that you have enabled the acceleration physics.

 

Also commenting that as many have already found, you can have two GeForce cards, one dedicated to the graphic and another dedicated to the physical part.

We can put our GeForce most powerful to accelerate graphics. And the other GeForce less powerful and less expensive to accelerate physics. And we do not need to be in SLI.

A big hit by Nvidia, for those who prefer to spend a little more money to get an exclusive card for physics may do so.

 

Also in the future when we buy a new card, the old may be left for physics.

Yes, but you need a mother board with two PCI-E Slots, aren't you?

 

Regards!

[Legolasindar]

Yes, I forgot that point, sorry :P. Fortunately the new motherboards usually carry more than one.

[Pilotasso]

How can I dedicate one GPU for PhysX with my 9800GX2? I didnt see such option.

[Legolasindar]

Correct me if I am wrong, but the 9800GX2 is a single card with two processors. For what you can not do it. We need two cards (not two in one).

[Pilotasso]

Its actualy 2 cards sandwiched on the same cooler and AGP slot. Other than that it works EXACTLY like 2 cards, it even has an internal SLI bridge. I see no reason why I cannot dedicate one GPU for PhyX since it works on my card.

[Legolasindar]

It's simple, we need that are in different PCI-E.

 

Anyway I do not have a 9800GX2, so I can not guarantee. The best thing is to try it yourself.

[Legolasindar]

This article analize this posibility.

Have various pages.

[Pilotasso]

thx!!

Probably because of that SLI bridgechip that the option isn't available to you. What Legolasindar describes doesn't work with GPU's already 'engaged' in SLI.

 

btw: with AGP you meant PCIe of course... :)

[Pilotasso]

Yes PCI-E :D its seems like yesterday I swiched over to this new standard :D

[HUAF-074]

PhysX is a future dream, because just few game support the physics engine.

 

For example: Unreal Tournament 3
