GeeCoolHow much performance mode helps a 13700HX depends on the laptop: some machines unlock 15-25 W more for the CPU, others just spin the fans louder. Turning it on while plugged in for gaming, rendering, or compiling is harmless; balanced mode is enough for office and light use.
Run a 15-minute all-core load in plugged-in performance mode and log CPU power and clocks: if power at minute 10 clearly trails minute 5, cooling is the bottleneck and no mode will fix it.
