This is our game. We are rebuild a game that had released about 10 years ago and uses PhysX 2.8.3 SDK.

We don’t know what is happened because we don’t have this SDK.

We want to get PhysX 2.8.3 SDK.

We cannot release this game now.

Our programmer figured out and fixed the bug using PhysX 2.8.1 SDK. So, now we don’t need 2.8.3.
Thanks for watching the topic.
