I've been wondering the same thing as well, but could never find a setting. By default in this mod pack, you get 3 perks per level which quickly makes your character absurdly overpowered. What's strange is, that the leveling overhaul (can't recall the name off the top of my head) that this mod pack uses specifically states that you're supposed to get a perk every 3 levels, so essentially as far as I know with the way it's setup you're getting 9x as many perk points as you should be.
I can attest that on my main character who's at level 54 or so, that the game is way too easy even with the difficulty sliders pushed up. Haven't even been using all the perk points either, because it's really too much in this state.
