Is the A330 in your hanger? How are the FPS there?
Dont forget you are combaring a non PBR VC with a full PBR VC too this can also cause some loss in FPS.
Disabling the FO Displays safes indeed FPS, I did that on my old computer too.
I remember in the previous version of the CRJ 700/900 product the G/S deviation scale and pointer were visible in PRI mode.
On the CRJ professional I can only see it in FD mode, but missing in PRI mode.
