Leave the application specific settings as default or reset to default.Leave the virtual reality prerendered frames to 1.From the 3d settings global options tab, set the power setting to maximum performance.Open Nvidia Control Panel by right-clicking on the desktop.Set the resolution close to the native resolution of the G2, about 50-60%, almost disabling all supersampling.Go to video options, select application specific settings and select il-2 sturmovik from the drop-down list.Leave everything on the global settings on except for the resolution, change from auto to custom 100%.
Steamvr and Nvidia Control Panel Settings The bottleneck is the GPU on this reference system. There seems to be a lot of headroom with that cpu and the amount of ram.

While the resulting visual quality is pretty low, spotting and reading the text on the instruments and gauges is still possible.
This guide tries to help others to get maximum performance and a stable 90fps frame rate in VR (G2) in il-2 BoS with older graphics cards (gtx 1070 or better) as the availability of new graphics cards is currently very bad.
