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. With these settings and similar hardware, you should be able to get steady 90fps in a quick mission with 10 planes and lots of ground units. 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.
