Go to your POWER OPTIONS from the control panel.
Power Options > Edit Plan Settings > then find “Change advanced power settings” > On the Advanced Settings tab find “Processor power management” > Click the + button to expand and you’ll see Maximum Processor State > CHANGE this to 99% instead of 100%.
You’ll see a HUGE difference on your CPU temperature.
“But 99% is only 1% less than 100% tho” Well yes but no, NEW WORLD is unoptimized so putting it on a 100% makes NEW WORLD use unnecessary amount of power from your CPU, but changing it to 99% will let it use enough power needed to run the game.
My temperature went from almost 80’c to 50’c after changing this setting.
So try it out, if it doesn’t work for you, then you can just change the settings back to 100%.
