I just noticed, I don't know if someone told about it, Asus Q-Fan or any other Fan Controller in bios, disable them, it improved my mouse control to steady speed, instead changing randomly speed every restart or randomly after some actions, can't even explain it. just disable it as other people say too. Just in the bios, no software installed in windows.
"System Management Interrupts
Many hardware systems use System Management Interrupts (SMI) for a variety of maintenance functions, including reporting of ECC memory errors, legacy USB compatibility, fan control, and BIOS controlled power management. The SMI is the highest priority interrupt on the system and places the CPU in a management mode, which preempts all other activity while it runs an interrupt service routine, typically contained in BIOS.
This behavior can result in latency spikes of 100 microseconds or more. If you need to achieve the lowest latency, look for a BIOS version from your hardware provider that reduces SMIs to the lowest degree possible, referred to as “low latency BIOS” or “SMI free BIOS.” It is not possible to eliminate SMI activity altogether because it is used to control some essential functions, such as fan control."
