Ok, that's getting interesting
2- i use it with arma3, as far as i know arma3 doesnt check anything with driver signature, but even if it does, you have to disable driver signature check to install the driver, after that DSC can (and will be) enabled again without any issue since the driver will still work.
are you using arma3 online? with battleeye active?
Cause i was using up to 2 months ago an old logitech mouse, which required a non stardard driver for being overclocked to 500hz, and so disabled driver signature check. Just few months ago, after a recent update, Arma3 started to refuse to start with battleeye active complaining that it required the driver signature to be active again.
You never had this problem? The signature is only checked during installation? not during usage (each time u start windows)?
