1. enable "Maximum Turn Speed indication" in āMore settingsā
If selected, when turn speed exceeds maximum, the LOGO will flash red twice.
then try your current settings, you will see when MAX speed has been reached.
2. you can lower your dpi to 6000, or lower the HIP/ADS to smallers ones,
and see what you get on LOGO.
PS: DO make sure ingame sensitivities are set to max
