PhysX

[zodiac949]

I've got an old 8400GS PCI laying around, and I kinda wanted to make use of it. Now I've been reading around a few forums, and I've come to find that people use older nvidia cards for running dedicated physx


My current video card is a BFG 9800gtx+ Factory OC


Would I be seeing a significant increase in performance if I went and did this?


If not... Are there any other uses for it? I'd hate to just leave it.



Thanks, zodiac

I'd say it depends if you play any games that actually use PhysX. Otherwise I believe the difference is minimal if any.

a lot of games support physics today. it might not give you a large performance increase, but it will make physics related things like ragdoll effect, explosions etc a lot nicer looking. also, an 8400GS would not fetch you anything if you were to sell it today, so there's no reason why you should not use it as a phyx card.

It its a spare, why the hell not?

 

[xbonez]

make sure you have the latest drivers installed to get the most out of the setup

 

[zodiac949]

I think I'll go for it then.



Thanks guys for the assistance

Good luck and you should see a bump in performance.

I thought You needed at least 8600 to use for PysX.

Anyway depends on game, I if the game does not have PhysX then obviously there will be no diffrence. If it does then it will not noticable difference on quad CPU because CPU has enough grunt to run PhysX on CPU.

On single or dual core CPU it might help to offload PhysX processing to GPU leaving more processing power for the rest of the game, but hthen again You can offload iot to main GPU if it is not taxed a 100%.

So Only scenario where it would be worth is if both GPU and CPU are heavily loaded or if You have ATI main GPU and second Nvidia GPU fotr PhysX but it will not work on Vista because it does not allow multiple GPU drivers and Nvidia has pulled support for it in new drivers for windows 7 if Your main GPU is not Nvidia and old drivers probably will not work good on W7

what ^^ says is true... you need atleast an 8600 for physx

Everything turned out all right. My BFG driver was able to pick up my PNY 8400GS, and I switched the physx over to it.

I read that nvidia gpu's that supported physx where 7, 8, 9 series - plus the fact that it worked anyway

The game I'm running is crysis, so yea, supports physx

No it doesn't, so it didn't do anything other than the placebo effect.

Crytek have their own physics engine, not PhysX. [:thegreatgrapeape:2]

Try Googling it if you don't believe me.
