Durant, who joined the already powerful Warriors from the Oklahoma City Thunder in July, made a trio of three pointers in a one-sided encounter.
The Warriors opened up a 20-point lead in the first quarter and never looked back.
Their lead had stretched to 102-51 by the start of the fourth quarter, an ominous warning to the rest of the league as the new season looms closer.
Warriors coach Steve Kerr gave more than 20 minutes of game time each to Curry, Durant, Draymond Green and Thompson before resting the all-star quartet.
Thompson reached his 30-point haul with only 14 shots but the biggest roar of the night was reserved for Durant, who opened the scoring early on with a three-pointer before later leaving the game to a standing ovation.
