Portals get clipping anomaly as you walk through them. All reflections are rendered at screen depth (no separation between left and right views). Portals look strange as they first appear. NOTE: Portal 2 requires iZ3D 1.12 drivers to run (1.13 did not work for us). Special baseprofile file can be found in comments section of game review or acquired from iZ3D.

Part IV: Secondary Anomalies

  • Render in render targets are not appearing correctly. Leading examples are mirrors, portals, and doorways that have their graphics clipped or clearly misrepresented when stereoscopic 3D settings are adjusted. For example, instead of seeing a full image through a portal, you see black or half black/half graphical image instead.
