When you launch the Program, the mouse sensitivity changes

Good day. When I launch Unreal Engine, the mouse starts to behave very strangely. The mouse sensitivity seems to be constantly changing, sometimes faster, sometimes slower. And this is not only in the program itself, but the sensitivity changes throughout the system, as soon as I turn off the engine, everything becomes normal. What could it be?

Hi @Snayper57Rus ,
I’ve been reading several old posts and it seems this is a bug that happens to many people. One of the possible solutions is to go to Project Settings, Engine and look for “sensitivity,” check that the values are correct; in my case, all the other values further down are set to 1 and the only different ones are the ones that say 0.07, just as a reference.

Another possible cause could be the use of software like Logitech G Hub, Razer Synapse or others, as they often create additional profiles automatically and that causes the sensitivity to change only when you open Unreal and go back to normal once you close it.

I’m also leaving the posts I’ve been reading, which although they’re old, might still give you a possible fix or at least some extra information.

I hope one of these options works for you!!!
