Mouse Movement Causing Visual Lag And Crashing

[xreggiex]

this problem occasionally happens to me since U14. sometimes, at the log in screen, if i ever move my mouse slightly, there will be a slight lag spike accompanying that slight mouse movement. so i tried moving the mouse cursor rapidly at the log in screen and after a while the game crashes.

 

i also tried logging in with minimal mouse movement and when i am in my ship, if i only move with my keyboard, the framerate is fine at around 230fps with vsync off. but the moment i move my mouse, there will be a lagspike. every slight movement will trigger the lagspike.

 

any help will be appreciated. i'm wondering what is causing this though. i will post additional pc specs as needed.
