Affected Gamemode/Excursion the ship itself, most noticeably in the Atrium and the Gmod Cruise Lanes areas but other areas are probably affected too Summary of Issue Encountered these areas are rendered even if you can't directly see them, which I suspect is a big reason for the Atrium area being particularly laggy I also suspect this has to do with the deck areas outside not being sealed with area portals (see screenshot with physgun) Expected Result the area you are not in should not be rendered (or at the very least greatly reduced) Actual Result almost the entire area you are not in gets rendered, resulting in unnecessary render times Steps to Reproduce set the following console variables mat_wireframe 1 mat_leafvis 1 (for reference) mat_DrawPortals 1 (for reference) and look for these areas being rendered behind walls Screenshots/Error(s) in Console (if applicable) of the Issue
Changing to Identified as we've talked about it some. It remains a difficult problem to solve, however clever use of Areaportals or Occluders might help
