FAQ: PhysX - Page 11

post #101 of 269
Do you run any games that use PhysX? If you do, then it will probably benefit you. If you don't, then it will just be extra power draw doing nothing.

And this stems from the 2+1 principle of SLI and PhysX...has anyone tried running a SLi setup with a dedicated PhysX card, such as a QUADRO? I'm about to make a build with 2 x GTX 480 + 1 x Quadro 4000. Shouldn't the quadro as a dedicated PPU be outstanding, because of its calculation power and 2 GB of VRAM? I dunno if anyone has ever used a QUADRO as a PPU.

are the new games mostly going to support PHYSX? or is this going to become a dead technology soon?

I used to think that it was going to pick up, considering some heavy hitters used it recently, but lately I've been getting the feeling that it will die off. There just aren't enough devs out there who are interested/using it. Or so it seems to me, going off the lists of games which use it, and upcoming games which will use it.

Guys, now with the new & cheaper models GeForce 430 & 450, do you think that adding one of them might help my system a bit?

I already have a GTX 480 but I don't mind adding a cheap 430 just for PhysX to reduce the load of my GPU.

just wanted to say I have got physx to work on my ATI4870 with a super old build of physx, it does all the cool demo's and stuff too.

I played the unreal3 physx levles just fine, it only runs a lil slow on the tornado lvl some times.

I did have to uninstall it however when I was running Dirt2 because I was told it causes issues with that game. I still have issues with the game tho.. just buggy I think.

Okay, let me make sure I have this straight: If I have a SLI/CrossfireX supported mobo (one PCI-E slot is x16, the other x8) I can put one GPU in the x8 slot (say an 8800GTS), dedicate it to PhysX, put a different card in the x16 slot and have that be my main card, BUT that main card MUST be an nVidia card? I can't, for instance, have an ATI HD6850 in the x16 slot and make the 8800GTS run PhysX in the x8 slot?

You can do what you're suggesting. There's a whole thread on it somewhere, it's been dubbed Hybrid PhysX, and it's totally unofficial and unsupported by nVid or AMD, someone called GenX has hacked drivers which allow it and it works a treat

It doesn't have to be SLI / xFire mobo anything either; just two (or more) PCI-e slots

Are there really only the 16 games listed on wikipedia that support physx? For something that's been around for this much time, I'm honestly a bit surprised.

I'll leave the above in place, if only to show how noob I am to physx. Here's my next question: Considering my sig rig, the only other card I have that supports physx is a 8600 GT. In your opinion, at 1680 x 1050, would the 8600 GT be an asset or a hindrance?

Thanks for any help
