V43 killing CPU so you rolled back to V42 a few days ago. All was now well. Why did you update to V43 again and not rectify the issue? CPU now working hard even when not using headset, AGAIN.... Task manager clearly shows Oculus software is not optimized again. So frustrating when the issue is known about and relaunched.
I had the same experience. The one-day rollback to V42 fixed the CPU load issue and my performance of iRacing was much better. When V43 returned the next day, all of the CPU load problems returned.
