discrete phys X card?

No. NVIDIA made it so that any time an AMD card is detected, PhysX automatically gets put onto the CPU. That being said, you can try your luck with hacked drivers.

No, Nvidia drivers prohibit it from working. Wouldn't be worth it as you'd loose a lot of performance.

I really wish Nvidia lent PhysX to AMD and let them use it too. It's such a cool but underused feature.

It probably would've become more popular as a result too.

can i buy like a cheap GT card as a discrete phys X card with my 280x?

If you have a decent CPU, then even if the drivers did allow it, you will not get a performance benefit with a dedicated cheap GT card for PhysX. If anything, it will decrease your performance.

Exactly. Nothing is more cool than finishing a battle in BL2 and seeing liquid blod and chunks of your enemy all over the ground!

I would still install the newest physx driver.

If their point is to use a dedicated PhysX card with their 280X, there's no point in installing the latest PhysX driver as it will be put onto the CPU.

i think metro last light installed phyx on my cpu and the result of that is unplayble frame rate at the lowest setting

Modified drivers and a bunch of tweaking works (i tried only a couple of weeks after nvidia banned it), but I found it creates more problems than it solves.

As I get older I get angrier more cynical, meaner. I feel some warning posts coming. I feel a ban coming. I was warned.

For AMD, not so much without a special driver, but with my GTX 970 and a 650 ti, I increased the maximum FPS of the 970 on its own, to the avereag FPS with the 650 ti handling PhysX, and the 650 was running off a PCIe v2.0 x2 slot (supposedly capable of x4, but that would mean sacrificing my wifi card)

Then disable it.

 I rann into games where you8n eeded the physx driver to run. and I've also had to uninstall a new physx driver and install an old one for a game to run. not going to hurt anything with the driver installed.

Hybrid physx is still doable of you have a 600 series or older Nvidia card, but having done it recently myself, I can tell you that the newest games that use hardware physx won't work. 314 nvidia drivers are the last drivers that you can really get hybrid physx working on. It's not worth it anymore imo.

Was it with Nvidia PhysX or another physics engine? Because I had no problems with Unreal Engine 3 based games.

I was just referring to Nvidia hardware physx. Most games that use nvidia physx are using software nvidia physx, which uses the cpu only (i.e. mass effect series), even if you are using an nvidia card.

You can force the GPU to render PhysX and that's how I normally see it being used. On the GPU.
