This is interesting! Is this the “global settings” page or custom settings for FS2020 in your NVidia CPL?
This feature is supposed to be “white listed” for each application by NVidia but there are tips to override this in using a tool to manage the internal values of the NVidia settings file (NV Profile Manager or something like this). However someone already tried during the FS2020 VR beta and this changed nothing.
Since you can change it in the CPL now, what is your feedback when in VR ?
