If CyperPunk2077 suffers from the same issues as we do, what makes you think we can do better?
What we did recently with navmesh is to set that thread to a lower priority which should help the OS in scheduling.
Funny thing, CP2077 with their 1.2 patch ended up doing the same thing with the streaming thread, lowering its priority s well which helped on PS4 Pro in bumping FPS, but meaning that meshes/textures are slower at loading... so when you zoom by in your car, objects will just fail to load because they didn't have enough time too.
