Another noob needs help with Kayran

[GamerNeedsHelp]

Hi. I'm fairly new. This is actually the first time I created a profile in a forum just to ask for help in a game.

 

I tried everything from lowering every graphics option to setting my game resolution to its lowest to modding the game so that i could instantly kill the menacing little hellspawn, but nothing worked. The rest of the game's performance is gold, my laptop just can't handle this one boss fight.

 

So, here I am asking someone with a better rig to please kill the little son of a bruxa.

 

Here's my save file: https://www.mediafire.com/?h0ewi3l82m563zi
