How to stop Thunder Clap lagging map?

[Marshmalo]

Hi, my map is very large as as a result it appears the terrain deformation caused by spells like Thunder clap, War stomp etc lags the map. The lag is clearly graphical as it's only this effect which causes the lag.

I tried changing the spell effect on the world editor but the terrain deformation is there, anyone know an easy way I can still have this spell in the map without it creating lag?

Base the spell off Channel, trigger the effect yourself?
