[vr] adaptive_resolution (off by default, in the VR tab) lowers the race's eye resolution by 10% steps, down to 70%, while new eye frames fall below 85% of the game's 60 FPS, and raises it again after three seconds on time. Adapted from heurazy/Wiicompiled_VR-PLUS. The eyes render into the top-left corner of the full swapchain image and the projection layer shows only that corner, so the compositor upscales them and no swapchain is recreated, unlike render_scale. The Linux same-device bridge now copies an eye smaller than its target; the Quest's bridge and layer already did. The PC's D3D12 path copies whole eyes, so the setting is not offered on Windows.
