Chaos is just 50 to 75% worse performance than PhysX. Period.
At this point I think they demonstrated that they won’t be addressing any performance issues with it.
It’s been years since the first beta, and years where the user base has constantly pointed out the massive performance loss from it. They wholly ignored it for years.
Their response has actually been to make it even harder to purge chaos out of a custom engine build to go back to physx.
If you need an engine with decent performance (even graphics), move on to something else.
CryEngine with paid Havok will work ok for large projects which can afford it.
UNITY offers a cheap version of havok too.
Unreal meahwile, has to be custom built with an older physx. And loose/miss out on a bunch of UI in versions above 5.
I don’t think it supports Havok any longer, since the system is essentially no longer modular when attempting replacement (ofc, if you pay for it, they likely give you a working source to build the engine with their physics, I hope).
Its kind of a mistery how the fortnite id10tcommunity hasn’t gone up in arms over the 5 to 15fps drops from rendering, and the additional unquantifiable drop from the chaos switch over. However unless their sales drop by 50% from it, epic will never care about any issue…
