Since the last two patches FPS drops from the usual 90 FPS in VR to 20-30, and occasionally single digits, after a few minutes flying around the TA at A1.
With DX9 or DX11 and no VR the same thing happens. FPS starts around 180 and ends up in the 20's. Even when the frame rate is 60+ I get pauses and stutters now.
Other games seem to run the same as before.
