These laptops are already pushing thermal thresholds with the extreme settings on the GPU side (raising GPU frequency induces throttling and normally has a negative effect over the stock extreme settings). Any difference I would think would be negligible and Im not sure it would be worth losing ROG Gaming Center to achieve them (ROG GC is not involved on other ROG laptops as much as this one). Please let us know though if you do see any improvements in performance doing away with ROG GC.
