Current state of PhysX? Is it well and truly dead?

PhysX heyday was Arkham City...that had some really amazing particle effects- the Penguin fight at the Iceberg Lounge looked gorgeous
I remember the tech demo of batman walking through a low-lying cloud of fog or something and the fog wooshed around his feet like what you'd think real smoke/fog would do should you walk through it.

I often wonder if it makes sense to make an add-on ray tracing card like the old PhysX cards.

It’s a shame that ray tracing can’t use a 2nd GPU just for ray tracing and let the first card do the rasterization. That was the idea back in the day with a dedicated PPU.

I thought the hardware to do the RT is separate from rasterization cores? If so, why would you need that on a second card?

Gone are these days, nvidia killed sli, amd the same.
I used another gpu just for physics in a mafia game.
Physics is the same invention of hot water by nvidia.
We will see how long this dlss will last as well as ray tracing.
Intel, amd and nvidia are not competitors although here in Europe everyone thinks they are and then they insult each other and measure which has a bigger one.

DLSS will probably not last unless Nvidia opens it up (which won't happen) but ray tracing has industry support so will probably be here to stay.

Metro 2033 was the first (and last?) game that ive played that used physx, I remember putting my old GTX 275 in the machine, clicking the checkbox for physX, and then spending hours staring at banners/flags/hair trying to determine if enabling physx actually made a difference or not.......I still dont know if it did

I think the sli bridge bandwidth would have to be way higher to facilitate ray tracing on another gpu

It would have to be around 300x higher to ensure no additional latency is introduced, and that is only for 60 FPS on an 11GB video card.

I just recently played through Darkest of Days and the Physx were neat, they under utilized them a bit though.
Cryostasis on the other hand, with the water and ice, it was really cool. More games need to use physx.

I also loved the original metro 2033’s use of physx for their smoke effects, it really added to the immersion of walking through old dilapidated subway tunnels and the smokiness of the homemade gun powder they use in their ammo.
