I would recommend upgrading the GPU, thats super important for high res VR. Then run DLSS Quality or Balanced and override resolution to something like 4600xXXXX or more using OXRTK. Don’t go above terrain LOD 100. Cap your fps to 45 using Rivatuner and ensure (using whatever settings) that you get a solid 45 at all times (maybe outside of the heavy cities a least). Oh and I would turn all reprojection off.
That’s the short version of how I got the most out of the G2 before moving on from it. Amazing headset for its time but once you see pancake or aspheric lenses you can’t go back!
