2 things I see that have caused problems for me. A) Hair Physics - can cause major hits on performance. B) SMP ( surface mesh physics ) can also cause major hits on performance. Have personally given up trying to run hair physics It just causes too many problems on my older Dell. Can run SMP on a main character without any noticeable problems. Most other tutorials recommend only running SMP and or Hair Physics on your main character. The game-bro engine can really struggle with the additional physics load added on top of everything else its trying to do. Changing the SMP and Physics related mods to basic static versions would be one path to explore for improving performance.
