Addresses reported stereo misalignment/double vision on Pimax and other canted-display OpenXR headsets.
The renderer previously discarded each eye's orientation and treated the left eye as the head reference. v0.2.7 preserves the runtime's eye orientation and asymmetric field of view, uses the binocular midpoint for native tracking/recentering, and submits the same pose/FOV used to render each eye. The character-camera HUD now projects through each eye's optical frustum while retaining its physical size.
The existing 4x/6x/8x/9x/10x presets, NoBloom, camera-blur control, pose timing guard, haptics, controller support and serial GPU retirement are retained. QPC/guard-band experiments remain excluded. The game-library ABI is unchanged.
Download the complete Windows runtime ZIP; dependency sources and SHA256 checksums are attached. No separate base app is needed. Back up your installation and preserve your own extracted/ and save/ folders when updating. Start SteamVR as the active OpenXR runtime and press F10 in gameplay to recenter.
Validation includes synthetic canted/asymmetric views at 0-25 degree cant and 58-74 mm IPD, 864 stereo point checks, projection edges, signed quaternions, render/submission agreement and HUD checks. An offscreen gameplay replay with 15-degree canted, asymmetric eye views completed at 3840x2160 per eye with zero missed draws or uniform updates; both eye captures were visually reviewed. The local Vulkan validation layer crashed before stereo capture, so this is not a clean validation-layer run; the normal runtime check completed successfully. Physical Pimax confirmation is still pending; this is an implementation fix supported by regression checks, not a claim of verified results on every Pimax model. Extremely wide peripheral visibility may still be limited by native game culling; this is not a general judder fix.
No game files, keys, generated game code, compiled game libraries, saves or caches are included. Supply your own Super Mario Odyssey v1.0.0 files through setup.
