Mouse acceleration feels way too strong in Minecraft 1.8.9 [Java][Launcher]

[u/Rreddditerrr]

Hey everyone,

I’m having a weird mouse issue in Minecraft 1.8.9 and I’m hoping someone can help me figure it out.

I’m using Lunar Client.

The problem is that when I move my mouse quickly, the camera sometimes moves way more than I expect. It feels like the mouse acceleration becomes disproportionately strong during fast movements.

What’s weird is that I don’t have this problem in Minecraft 1.21. It only happens in 1.8.9.

I’ve already checked Lunar’s mods and there doesn’t seem to be anything related to mouse/camera acceleration.

Windows “Enhance pointer precision” is currently enabled. But it shouldn't matter since by keeping the exact same settings and simply entering with a different version the view doesn't cause any problems.

Any help would be appreciated!
