If I raise it up very high it makes the saber invisible. I think it may have to do with the following.
"g_saberDmgDelay_Idle & g_saberDmgDelay_Wound now control how often often hits against the exact same target will register. This is to prevent the damage levels and saber/dodge behavior from acting differently when you're using a higher sv_fps setting. This translates to more consistant damage as well."
JRHockney and I were checking out cvars and when we raised it through the roof so that these lightning parries stopped happening, JRHockney's saber continued to go through my intangible saber (the hits not registering because it was too high). I don't think these lightning parries can be fixed with any cvars, I have tried many cvars and no luck on my part.
