Hi Tom, very many thanks for your HU. I unchecked the Vsync box and whilst no improvement on fps X-Plane 11 now feels much smoother. I have tried altering my graphics but still getting 25-26fps. Even though this is a slight improvement I still feel as though the Quest 2 is not as good as it is in Steam for rFactor 2 and Dirt Rally 2 is very good. I know that the graphics will be very different in those games but wondering whether it might be down to my graphic settings in Nvidia?
