I recently installed Technic launcher and ran tekkit classic, it used to work in the past When i play there is an extreme delay with my mouse where i would move it and there would be a big delay where it would jump to the position. It isnt tekkit lag as i can use my track pad to look perfectly fine, it is only mouse lag (tried other mouses still dosent work) I tried launching classic minecraft from technic launcher and there is NO problem. I tried re installing Java and Tekkit, still didnt work. Help <3
