Developer Notes

We replaced this with the local file streamer as the default (it performs the file operations on another thread) in 4.23.

Steps to Reproduce

In 4.22 , the FFileHandleWindows.Flush  was override and implemented, so it will cost a lot of time every tick time when recording.

Profile in 4.22:
