When the headset is active, frame-rate is being locked/synched to 90fps, even if your cpu/gpu could push further. It's a similar principle to having v-sync enabled on a monitor.
And there is the problem. ASW is locking it to 45 for a duration every time it has a slight dip below 90.
If it dips below 90 it is by design going to halve the locked FPS rate, to 45, because the goal is to avoid any frame tearing on the display. This is similar to how consoles will dance between 60/30 FPS to prevent frame tearing.
Do you get drops to 45 in an empty scene?
