Общее Использование имеет медленный Framerate

это особенно примечательно в редакторах кода, где там больше чем обычно перерисовывает продолжение. Но задержка также происходит в веб-браузерах при навигации и прокрутке. Прокрутка, кажется, отстает, также. так.. не уверенный, что продолжается там.

Я даже не знаю, где запустить.

Вот некоторая информация о системе:
