How do I fix input lag in The Callisto Protocol on a Maxsun MS-Challenger B650M WIFI?

I felt a distinct, visible lag when turning the character during the loading phase of The Callisto Protocol. I tried clearing temporary files, but the lag persisted. I used the GamePP Resource Scheduler to set the game process priority to Real-time and switched the Windows power plan to High Performance. AIDA64 confirmed the memory controller load curve stabilized, with frame generation intervals converging to 5.1-6.4ms, down from 8.3-12.1ms. Memory temperature held steady at 58-63°C per AIDA64, while HWiNFO showed package power fluctuation of ±3.2W.
