Custom NPCS, Low Frame Rate? in Noppes' Mods Posted March 14, 2018 · Edited March 14, 2018 by n00bUltima · Report reply Hello, this is a great mod and I really like it! I use it to liven my worlds a lot and it's working greatly. However, I just reinstalled the mod to a newer version and now whenever a NPC is in my field of view my frame rate drops by about 10. I tried to get the earlier versions, but it still lagged a lot. This did not happen before, and I'm wondering what the reason behind this is? I did install some new mods though and uninstalled some as well, so are there any conflicts that may lead to this? edit: Running 1.7.10 with the d version currently.
