FPS limiting in VR

[Chief Instructor]

I have been limiting my VR FPS to 45 using Afterburner prior to it being a feature in-game. However, I'm finding that using the in-game setting now only seems to work if, once loaded into the aircraft, I then hit Escape and open the options menu at the system page. As soon as the page opens, the FPS come down from around 60 (or whatever) to the 45 limit I've set.

Does anyone else see this behaviour?
