I am using a new laptop Dell Inspiron 7590 with 4k screen. Other specifications are i7 9750H + 16GB RAM + Nvidia GTX 1650 dGPU. I do not think the lagging animations and lagging Chrome/Word/Excel experience should appear in this computer.
The symptoms are very similar to some previous threads as in:

In the first thread above, the problem was finally solved by using the updated Intel graphics driver. However, when I tried using the latest driver from both Intel and Nvidia, the problem persisted. Therefore I hope to get some help at this community. I look forward to any response. 🙂

Since you have dual graphics, you MUST use the Dell drivers for both Intel and nvidia graphics.

Thanks for your response. The computer used the Dell drivers initially but the lagging problem showed up. I will try uninstalling all current drivers from Intel and Nvidia official website and install those directly from Dell instead.

Thanks for making this post. I was wondering if you are still experiencing this issue?
I have an Inspiron 7591 with very similar specs to yours: 4K + i7 9750H + 16GB RAM + Nvidia GTX 1650 GPU. Windows 10 + all Dell and Nvidia drivers are up to date.
On Windows 10, I seem to experience lag when screen sharing with MS Teams whilst running lots of browsers and apps at the same time. Teams GPU hardware acceleration has been switched off as I experience fewer problems with it off.
My current setting for Win 10 is to use the Intel GPU for all apps (all non-games / work-related apps) seems to be the optimal setup. When I try to use NVIDIA GPU as the default or for specific apps, it seems to introduce more intermittent lag (and fan spins up more); particularly when Teams/Zoom is being used to screen-share.
I don't know if it's:
- Windows 10 simply works better with Intel GPU on laptops with dual GPU?
- It's not possible to set Nvidia GPU as the main GPU on windows 10?
- Something I'm doing wrong? Drivers? Config?
Any advice or insights will be much appreciated!
Thank you!
