Windows 10: Intel + NVIDIA Laptop Freeze Problem

Hi everyone, I have bought Lenovo legion 5 15ITH6H less than one month ago and I experienced freeze/lag issue, how to produce? I open a game that require the dGPU to be activated and then close the game now every app every action I do will cause the mouse and screen to freeze for a second and its very annoying the only way to get rid of it is to restart the laptop but if I play a game or use any app that require dGPU and close it the problem happen again... I partially fixed it by disabling the hybrid mode so now my laptop will only use the RTX 3060 but it will drain a lot of battery I formatt

[Critical Bug] Intel + NVIDIA Laptop Freeze Problem

Inspiron 7577 / GTX 1060 / Win10 v.1803

Okay, I understand that it is Windows, not NVIDIA, causing the issue. But the thread is called "Intel - NVIDIA Laptop Freeze Problem" so I am just reaffirming that my NVIDIA-GPU laptop is experiencing the issue.

I want to add my name to the list of users experiencing the bug, in hopes that it will expedite the hotfix/update from Microsoft. I know that my computer is already in the affected list.

Anyways, I just installed Win10 v1803 and I still get the freezing, primarily in chrome/edge/firefox/opera etc. I'm really surprised this problem has existed for so long.

 

AMD + NVIDIA Laptop Freeze Problem

I am writing a new thread to mention an issue about AMD + NVIDIA laptops using NVIDIA Optimus technology. This seems to be a very old (+8yo!) bug reported first for INTEL + NVIDIA configuration, but it was partially fixed for INTEL by cooperative work between Intel and Microsoft. It doesn't seem to be fixed for AMD though.

Observed issues:

1. Laptops utilizing NVIDIA Optimus technology have 0.5 second stutter on integrated GPU when using particular Windows UI elements:

• Clicking on wifi/speaker/battery icon
  
• Right clicking on Desktop
  
• Using "lock account" option in Start Menu / Your account name
  
• Clicking on Restart/Shutdown in Start Menu
  
• Sometimes when using browser (I can't tell exact moments)
  
• Sometimes when maximizing minimalized apps
  
• Sometimes when changing resolution or opening apps
  

2. Laptops stutter on battery power. Happens on both AMD and NVIDIA, but never on both at the same time. What does it mean:

• Hibernating a laptop and waking it up will most likely make AMD stutter entire system every 10-20 seconds. Turning on NVIDIA-powered app will make stutters disappear for that time.
  
• Turning on or restarting laptop will make NVIDIA GPU stutter every 10-20 seconds when dGPU is used. Turning off an app that requires NVIDIA GPU will make stutters disappear for that time.
  

As you can see from the observed issues, the 1st point is exactly the same issue INTEL+NVIDIA setup laptops had in the past (and partially still have).

This issue was first reported for INTEL here:

But I have also found topics speaking of similar issues on AMD+NVIDIA powered laptops:

From what I have seen Lenovo and HP brands are affected by this issue, but it might be way more spread considering this is an NVIDIA Optimus issue with AMD+NVIDIA configuration.

The 0.5 stutter looks like this:

And the stuttering every 10-20 seconds is like this:
