Severe performance degradation when using multiple Input Action mappings
How to reproduce:
1. Open the “Input_Action_Amount_Performace“ project
2. Open the “SampleScene”
3. Open the Profiler (Window > Analysis > Profiler)
4. Enter Play Mode and while moving the mouse in Game view observe the Profiler
5. Exit Play Mode then in Hierarchy disable the “BobSpawner” GameObject
6. In Hierarchy enable the “FredSpawner” GameObject and Enter Play Mode
7. While moving the mouse in Game view observe the Profiler
Expected result: there is no major performance difference between the two GameObjects
Actual result: “FredSpawner” GameObject causes major performance degradation
