I'm getting some horrible lag spikes after upgrading a project to 2018.1.0b4. The Profiler says it's being caused by FixedUpdate.PhysicsFixedUpdate,and the main offenders appear to be PhysX.PxsAABBmanager.actorAABB and PhysX.ScScene.postIslandGen. It only happens with the FPS Controller and not a static camera. Anyone else have this issue? I know this has been an issue previously but as I've made no changes to the FPS Controller between 2017 and 2018 can only assume it's an upgrade issue?
