Shock spell arc fx is delayed, sparks = few seconds to appear, thunderbolt never appears unless spamming and then only for a second

[Kaioken100]

Trying to figure out the reason for this weird bug forever. 

Simply put: frost and fire? Normal.

shock? Concentration spells take a second or two to start, sometimes work normally. Casts almost never show up unless spammed. They hit targets but the arc is missing. 

using voltage textures but bug was before installation.

using comprehensive first person overhaul.

using goetia third person magic animations.

the bug goes across vanilla spells and all modded ones that have the ‘arc’.

using mysticism & forgotten magic.

what could cause this specific oddity?
