Not sure if it’s worth mentioning but I have seen some odd juddering using reprojection (OXR) in scenery where it’s otherwise been completely smooth during the flight - no apparent loading or heavy scenery involved - just appears out of the blue.
I put this down to the use of ‘Automatic’ setting on OXR as I had it on by mistake and I usually fly with ‘Always on’ which has never caused me a problem and it seems to be more efficent.
