Lately been playing at 100 to 115 % resolution (depending on map, aircraft, to maintain over 60 fps with margin) in OpenXR at 60 hz on G2, motion reprojection off. OpenXR Toolkit fixed foveated rendering at high quality preset. DCS Textures and Terrain Textures both set High, Anisotropic Filtering 16x, but most other DCS settings low/off. Using 3dmigoto mod for Apache rotor removal, haze removal, crater fps fix, and sharpening (lately set to around 2.2) Getting lots of shimmer, but I've kind of gotten used to it, and am addicted to the level of detail - seeing numerous details I'd never seen before!
In my opinion, this plays to some of the G2 strengths, and allows the potential sharpness of its displays/optics to be realized without artifacts or judder. It does entail Oculus Dev Kit 1-like 60 Hz with flicker, but I've gotten used to the flicker after playing this way for awhile. Seems to me like there's not a very great antialiasing solution for DCS VR yet, so for now I've embraced the shimmer. 3090, 5950x, 64GB, Windows 10.
