Hi,

there is a problem with laptops which have Intel CPU + GTX 1050/1050Ti/1060/1070/GT 640M. The problem is, whenever you try to do some action on the OS, discrete GPU is triggered and it causes a 0.5s freeze.

Some actions, which cause the dGPU to wake up and lock up the whole system for about 0,5 seconds are:

Left click on battery-icon in task-bar

Opening Chrome-browser

Opening Windows Image Viewer (app + classic Foto viewer)

Opening system control panel

Provocation any animation on task bar (e.g. thumbnail-preview, ...)

Loading a new tab in Firefox

Here is a video demonstrating Display Setting Freeze:

Another video showing dGPU switch on a lot of simple tasks:

Another one:

We have tried updating every software possible, but no luck.

Intel driver

NVIDIA driver

Chipset driver

BIOS

Firmware

The problem can be found on all laptop brands: ASUS, Acer, Clevo, Dell, Gigabyte, HP, Lenovo, MSI, Razer.The problem can be solved by either disabling Intel GPU, which forces the system to always work with NVIDIA, or disabling NVIDIA GPU. Both of them is not an option though, as if you disable Intel, not only you will drain the battery faster, but also some games will stop working. If you disable NVIDIA, then what is the point of buying a laptop with a discrete GPU?There is a also a workaround: configuring https://github.com/jobeid/TrayPwrD3 TrayPwrD3 to always work with NVIDIA in the backgound. This keeps the NVIDIA GPU alive but also drains battery faster. And there is no poaint in that as it renders Optimus useless!So, manufacturers have to come up with a fix.Thank you.
