These are actually two slightly different options. Mouse sensitivity is how far the cursor or camera moves based on how far the mouse moves. More sensitivity means that the camera moves more if you move the mouse the same distance.

Mouse acceleration tracks how fast the mouse moves over that distance and extends the amount the camera or cursor moves if it moves faster or decreases it if it moves slower. In some cases this can feel more natural, but in others it can make it harder to be both fast and precise in your movements, since moving faster can make you overshoot compared to making the same movement more slowly.

Would you believe that there’s a racist element to this as well?

So first off, Ukraine couldn’t have joined NATO because of the active territorial dispute re: Crimea, which had been ongoing since 2014. But more importantly, please for the love of God stop following the cold war colonial logic that only Great Powers have any agency in their own international affairs.

Poland, Lithuania, and all the rest of the countries that Putin wants out of NATO are in there because they wanted to be, mostly because they wanted security against Russian invasion. Like, Poland basically blackmailed President Clinton into expanding NATO by threatening to support the Republicans in the next election.

But why would anyone be worried about Russia invading them if they tried to exercise independent agency and leave Moscow 's sphere of influence? Oh wait, look at what’s happening in Ukraine. Maybe those fears weren’t so unfounded. Sweden and Finland certainly seem to think so, since the war led to the most significant expansion of NATO in decades and gave NATO a direct land border within spitting distance of Moscow.
