How to mod fire sprites (burning effect) out of the game? They drop my FPS horribly

Basically thread title. Is there any way to easily remove the fire sprites that appear when an enemy is hit by a fire spell?

I'm playing on an intel chipset and the game generally runs smooth as butter. Only exceptions is on the new map zoomout animation (which I can live with), the new character sprite outlines (which I can turn off) and whenever an enemy gets hit by a fire spell.

With the latter, the game slows down immensely and stutters out of control up until the burning effect completely dissipates from the screen.

It's not the spell effect itself, because when I cast a fireball or flamebreath, and it hits nobody, the game keeps running smoothly. Not to mention I can clog up the screen with grease, entangle and a bunch of other effects and the game doesn't seem to drop a single frame. It's only with the burning sprite.

This has been reported before, but, unlike this guy, I don't just drop to 20 fps:

In my case, the stuttering is so strong that my game gets completely disrupted for a few seconds (probably the same bug, but my hardware is just overall worse than his). Any help greatly appreciated.
