@antheas Just needed to increase the TDP Limit to 10 watts and with a Manual GPU Clock of 1200 MHz I am getting slightly lower Total Power Consumption on Middle Earth Shadow of Mordor than I did on Powertools while having good enough frame pacing with the FPS Limiter Disabled.
BTW if you are interested in playing the game on Deck/other handhelds make sure to set the Anti-Deadzone to 14,000 with Response Curve set to Extra Wide on the Right Stick. The game has huge deadzones on the right stick.
