Initial steps: 1) Cull light-list of all ai_see lights to reduce the radius checks 2) Radius check lights to the player 3) Mark out-of-range lights for suppression Note: lg_weak appears to use spherical checking, see if changes from 3584 can be used instead. |

Cutting off all lights that are not "viewInsideLight" doesn't improve performance. Next test is to cull all noshadows surfaces except for the lightgem. Changes will be done in interaction.cpp and RenderWorld_portal.cpp |

Conclusion: No huge (real-world) gains but reducing the lightgem process time allows you to set tdm_lg_interleave_min lower while tdm_lg_interleave = 2 and tdm_lg_split = 1. It should allow low-end players to have a much better experience. High-end folks haven't chimed-in on whether this also allows them to increase image quality options but it seems that it should help there too. |
