Why is the Ubuntu interface slow?

Question

linux

My PC is i5 4590K, GTX770, 8gb 1600mHz
Ubuntu 16.04 Installed a
proprietary video card driver
Despite this, the OS interface slows down, freezes.
For example, when dragging a window, it jerks behind the mouse. In VLC, when rewinding the video, the picture freezes, is distorted, while the sound goes on.
It turns out that the legend that Linux does not lag is a lie?

Answer 1

You need to make sure that the Nvidia graphics card is enabled and not the one built into the processor.

Answer 2

I read somewhere that you should not put proprietary firewood in favor of free ones, which are already part of Linux. Try without video card drivers.

Answer 3

It turns out that the legend that Linux does not lag is a lie?

Of course, Linux has the slowest GUIs. Perhaps with the release of Mir, the gui will become more responsive.
But you, apparently, just have a problem with the drivers. Install normal proprietary drivers and lag will be noticeably less.

Answer 4

Goodnight.

Answer 5

There are many legends about linux, for example, that it does not hang. Hangs and how. And FreeBSD hangs. Everything hangs if crooked iron. Excuse me, do you definitely use NVidia, and not integration? Xorg.conf is there or does everything work "by default" (X will start without xorg.conf)? What was the purpose of installing firewood from Nvidia? During my time under FreeBSD, the free nv driver didn't want to work properly with my card, so I had to use drivers from NVidia.
Normally configured linux does not lag, does not hang and is absolutely resistant to viruses. And almost the same can be said about Windows - it's all about the tuners ...
