GeeCoolPerformance mode only matters plugged in and under heavy load. Run the same task in Balanced and Performance on the same machine and compare times: no difference means stay in Balanced — it's quieter and cooler.
On many flagships, Performance mode just spins fans faster without touching the power wall, so frames don't move. Check review power data: if wattage didn't rise and FPS didn't rise, the mode is decorative.
