I started streaming Twitch…
And every time I stream my sensitivity in Minecraft is weird, I can't describe it but I can try.
So if I move my mouse in one direction now, it's normal, and then quickly for a short time and then slowly again and again quickly.
How so?
Maybe you are lagging Can of course happen through streaming if you don't have a decent internet connection. You can see what your ping looks like while playing. Normally it shouldn't be over 50, everything above then usually gets jerky.
Here I can recommend you to turn down your stream quality. You don't usually need more than 720P. If it is still lagging, you would have to go further down or you need a better internet contract.
