Why are 500hz and 1000hz mouse polling rates leading to lag?
Why are 500hz and 1000hz mouse polling rates leading to lag?
I just purchased the new mouse rival 3 and attempted to start in safe mode. I verified the corrupted Windows files (DISM.exe, sfc /scannow) but found no changes. It seems the issue is with Windows itself, especially because it works perfectly on another computer.
It looks like the issue with the polling rate has been resolved. I followed the steps in the bios settings → advanced settings → CPU configurations → Disable C states → save and exit. After completing these actions, I checked my mouse polling rate and it is now set to 1000hz, with no stutter or FPS drops in any games. Hope this helps.
I also looked into this today and found that turning off C-states resolves the problem, though it keeps the CPU in a high power mode constantly. I tried different C-state configurations that my BIOS didn’t show, which led me to the lesser-known "C1 state auto-demotion" feature. This lets me retain all my important C-states. It seems to use a smart approach, stopping a CPU core from entering a deep power state beyond C1 if it’s woken up often. I’m using a tool called msr-utility from 'cocafe' on GitHub to set this up at boot and reapply it after standby. Setting this up required creating a task scheduler entry, but it’s the most effective solution for me until ASRock makes the setting available directly in BIOS.
I completed the task and here it is, I disabled c-states completely.
Edit 1 CPU remains at 3.4ghz across all cores, which is the maximum frequency, though unfortunately it didn't resolve the issue. Still, the lag from Windows dragging persists, but I've adapted to a 250hz polling rate.
