@MADZyren is probably right. I had a laptop that would run the CPU up to 90c in most games sometimes crossing into the mid 90s, and when I called the manufacturer, they told me it was meant to run at that temperature. Thermal throttling may be occurring in your case and the balanced power plan could be preventing your hardware from stretching it's legs too much, stopping it from overheating and losing performance.
