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.PhysX heyday was Arkham City...that had some really amazing particle effects- the Penguin fight at the Iceberg Lounge looked gorgeous
I've wondered about that too, but I think that PCIe has too high latency and too low bandwidth for intersection accelerators to be that far from the main GPU and not have performance issues.I often wonder if it makes sense to make an add-on ray tracing card like the old PhysX cards.
I thought the hardware to do the RT is separate from rasterization cores? If so, why would you need that on a second card?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.
