（New）MotionAssistant v1.2.0.5 (03/21/2025)

v1.2.0.5 2025-03-21 1.Fixed the issue where some games could not properly lock frame rates when switching to game-specific configurations. 2.The RTSS frame rate lock list now includes display refresh rates for monitors greater than 120Hz. 3.Optimized CPU frequency locking logic and fixed issues with sleep/wake and switching game configurations not properly locking frequencies. 4.Added an automatic power-saving mode for CPU frequency locking, which adjusts power-saving settings based on CPU frequency levels, automatically enabling core parking to reduce CPU power consumption. High-performance mode is used when the main frequency is set high. 5.Removed the CPU big.LITTLE scheduling option for CPUs without a big.LITTLE architecture, allowing only full-core automatic selection to avoid performance anomalies. 6.Optimized fan control logic to reduce CPU usage. 7.When the GPU frequency is not locked, clicking to increase or decrease the GPU frequency defaults to adjusting from a base of 1000MHz.
