# Quantum Espresso energy cutoff for different pseudopotential

I've been told that I should use the potentials from the Standard Solid-State Pseudopotential (SSSP) library in my simulations. I am interested in $$\ce{Pt}$$, $$\ce{O}$$, and $$\ce{H}$$. Oxygen is Projector-Augmented Wave (PAW) while platinum and hydrogen are Ultra Soft Pseudopotentials (USPP) (I am surprised that quantum espresso is able to run multiple PP descriptions at the same time).

The advised energy cutoffs for platinum, hydrogen, and oxygen are $$35$$, $$60$$, and $$\pu{50 Ry}$$ respectively. My system is made of $$85\%$$ platinum and a few oxygen/hydrogen atoms, do I still need to use ecutwfc = 60? It seems like a waste of time in this case?
