If a game uses PhysX, it does not mean you will notice it. It might not have obvious PhysX effects in it. It might not have cloth, or PhysX particles, or water effects, etc.
These are just flashy/trendy effects that are easy to advertise/sell/etc for the marketing people. The kind of stuff that gamers care about, maybe. But this is not the important part.
The most important part is the one that you don’t see. The one that makes you game playable at all.
When you fire a gun in a FPS, that’s PhysX (”raycast single” scene queries).
When NPCs/AI see you, that’s PhysX (”raycast any” scene queries).
When many NPCs properly interact and avoid going through each-other, that’s PhysX (broadphase).
When your character simply moves in the level, that’s PhysX (”sweep” scene queries, or even PhysX’s character controller).
It’s not just about ragdolls or particle effects. PhysX is also there supporting the invisible foundation upon which everything else is built.

Lol like the quote “PhysX is also there supporting the invisible foundation upon which everything else is built”, makes me think of the simpsons freemasons episode… ????

Well… One of the people who contributed to PhysX is an actual, genuine Freemason. Now deal with that, Internet!
