PhysX is the default physics engine in both Unity and Unreal. Which means it is used in tons of games, on a lot of different platforms (PC, Xbox, PS4, Switch, mobile phones, you name it). “That game does not use PhysX because it is not listed on X or Y“: potentially wrong. Some people pointed out the lists of “PhysX games” found online as “proofs” that PhysX was dead and not used anymore. Unfortunately these lists are incomplete. Even the one on Nvidia’s own website is not up-to-date. There are a couple of reasons for this: PhysX is kind of “done” now, and more-or-less in maintenance mode. “GPU PhysX” can mean different things, and admittedly the differences are not always clear or obvious. If we’re talking GPU particles or cloth, they have indeed been deprecated in recent PhysX versions, replaced with FLEX (an entirely different engine, unrelated to PhysX so far). The FLEX implementation is better, so there was no need to keep supporting both. http://www.codercorner.com/blog/?p=2013 I posted this because I've seen a lot of posts about Unity engine not working on AMD hardware. Be that it's fixed by now (or not). It's clear where this engine tilts towards.
