Hi.... I've been playing Half Life 2, CSS, and Garrys Mod alot. And just recently in Garry's Mod, my mouse response time has slowed.
I've closed everything BUT Gmodm and the mouse will work perfectly in the menus, but when browing items (Q button) and looking around, it has slowed.
Ex: I'll mve the mouse to the right, and by the time my mouse has stopped moving, THEN my player will START looking to the right. It's pretty annoying......
