Weird sensitivity on Windows 10 version compared to Java

The sensitivity is weird. I can play perfectly fine on Java, the sensitivity feels just fine. But when I get on the Windows 10 version, the sensitivity doesn't feel as precise. It feels like the sensitivity is on ice, is the best way I can describe it. Turning down the sensitivity helps, but it still doesn't feel as precise as the Java version. Why is this, and what can I do to fix it? It's driving me insane and I don't understand why the sensitivity would be any different at all. I've tried checking my settings and everything, it's not me.
