I moved the yard lights around a bit and tweaked with size with this in mind and found a considerable increase in performance. Very solid advice, thank you. Next I'll look into converting stuff into func_statics - I've done some in the past, but I've got pretty mixed results performance wise. Is is better to make multiple individual func_statics, or try to lump objects together into one big entity? I understand that if the entity becomes so big it crosses visportals, that will be unefficient, but what about outside where I currently have no portals in place? Sorry about all the questions! I'm sure I could find this stuff out just by reading more into old threads / the wiki, but nothing beats the convenience of asking from those who know better Fantastic! One of your jobs will be to try and break the level as bad as you can, so being adept at shenanigans is exactly what it takes. I'll do one more pass on the map and then pack it up for you guys, expect something in your PM boxes within... let's say 24 hours.
