Windows 10: Dell Precision m3800 stuttering and lag

Hi All,
Just wondering if anyone else has seen these type of issues. I did an in-place upgrade on my brand new m3800 laptop and am getting graphics stuttering and lag. I also have noticed that if I open the nvidia control panel, the 3D preview window is completely grey and doesn't show anything. I don't see CPU spikes or anything else indicative of issues. Anyone have any ideas? I can try a clean install as well, just haven't had time yet.

:)

 

USB Modem Not Working

Hi Ruth,

I appreciate the feedback! Maybe I've confused you but my system (laptop) is a Precision M3800, not an Inspiron as you mentioned. If you follow the below link you'll see that Win 10 is indeed supported.

Thanks for the help again.

Mouse Freezes on windows 10

This issue was driving me crazy for months on my Dell Precision M3800.

Finally I found the solution in my case!

In device manager I had to deactivate in the sensors-section the STMicroelectronics Accelerometer.

I tested all available driver versions for it, but NONE is ever working together with the Dell-Touchpad.

Fun-fact:

When I was travelling and my Laptop was shaking my Laptop (in trains and Planes), then my mouse was nearly dead.

That is the reason why I came to the accelerometer...

 

Try reinstalling your Video Drivers. Most likely the OS has installed a basic driver. Use the Windows 8.1 drivers, they should work fine.

 

Indiana,
I gave that a shot, but it didn't fix it. I tried using Driver Fusion to remove any remnants, which then put me in a boot loop. I wiped the laptop and completely fresh installed. The system is still stuttering and I see the spinning dots animation on the login screen and other places freezing for as much as a two seconds sometimes. There are no CPU spikes or other problems to explain this. I suspect that this laptop has Optimus and I'm wondering if that is the problem. I just got it about 2 hours before I installed Windows 10 on it.

Edit 2: Confirmed nVidia Optimus is broken on Windows 10 for the time being. I suspect that is the root of my issues. There doesn't appear to be any way to turn it off either.
