My Armature rig slows Blender down When selecting small groups of bones in Edit Mode it runs fine, but using Pose Mode and trying to move a part of my character or trying to move the rig or character in Object Mode it lags the program a lot. I used the Rigify add-on to add in a Human metarig and the lag arose when I parented it to my character.
I fixed the issue. It lagged because my model had WAY too many tris. I heavily lowered the tris, restoring the original speed.
