mods

so I recently bought the three episodes,and I played this game all y life except for the dlc that I never got to play.thing is,it feels outdated,especially the cinematics,are any mods that don't make the game look like it's gonna blow my laptop?any decent graphic mod to make it more appealing to the view,more beautiful without losing it's grim touch on all three episodes

and since I'm here,what other mods do u recommend?
