I always deselect this when I install the nVidia driver in Windows. I play none of the few games that are supposedly enhanced by it.

You probably do, as unreal engine and unity both use physx. Just not the old system level libraries that are used for old games.

ok, cool, didn't know that

Incidentally UE with 4.26+ (and more so 5, which is almost a complete cutover) switches from PhysX to their in-house solution of Chaos.

A lot of it has to do with determinism over the network IIUC.

4.26 and 4.27 still use physx by default, and their chaos version is basically unusable[1] (because of bugs and performance). There is a 4.27-chaos branch which is more updated (maybe the same version as Ue5 chaos?) but I don't know how usable it is.

But yes the future for UE is chaos.

[1] to be fair fortnite used it, but clearly they optimized and fixed only the subset of features that fortnite uses.

I can only think of Planetside 2 from back a ways, but they removed it for the PS4 release. Cool tech, though, I enjoyed it.
