Attempting to play in editor, standalone, or VR Preview when a behavior tree that is running is open will cause a significant performance decrease. The framerate drops from ~120 to ~80 fps while the BT is open. Closing the Behavior Tree returns the framerate back to 120.
Found in 4.12 Preview 4. Reproduced in 4.11.2 binary and Main CL 2980114.
1. Open the attached project
2. Open AI_BT
3. Run VR Preview (Ensure that you are viewing the debug flow on the Behavior Tree)
Result: Notice that the framerate is around 80 fps, instead of the usual 120. Closing the behavior tree will bump the framerate back up.
Expected: Framerate would remain consistent, or not experience such a significant drop.
