Even with the latest version? Honestly, I trust Epic and the Unreal Engine team so I feel like it can’t be performing terribly, but if it was, then I feel like Epic would be aware of the problem and would probably switch to another solution in the future. Tim Hobson has a really good point, Epic wouldn’t make a decision based on personal bias. My point is, are you sure it was the latest version of PhysX that was running on 1 core?
Either way, I’d love to see some kind of complete analysis with benchmarks or even thread usage visuals (something like this but for the latest version of PhysX, as that one is from back in 2009), mainly to see how much better it performs now than it used to, and also to see how it performs against other physics solutions like Havok and Bullet if possible. Unfortunately I’m not really experienced enough to really be able to do this analysis myself. I’m not really a technical guy (I’m a 3D Artist, and still somewhat of a beginner at that) and I’ve only just begun seriously learning UE4. It would be really cool if Epic would be able to do the analysis officially, but I’m sure they have a lot on their plate so I doubt they’ll have the time for something like that.
