Hi John,
Thanks for the tips but sadly I pretty much do all this as per my normal process. Browsers are always closed, Orbx is closed and about the only software running is Navigraph Simlink.
My OpenXR settings are 100% render scale (have tried it off but no difference) and reprojection off and experimental version disabled as well.
I am sure if i really want to get it smooth I could turn everything down to pretty much off or low but I dont feel its worth it for just 1 airport out of about 50 I have bought for the Sim that all work flawlessly with my system.
Again appreciate the reply though but for now I have uninstalled it.
Cheers
Barry
