Lagging animations at 4K resolution (running at Windows 10)

[AAhma8]

Hey there, I'm using Asus Zenbook UX510UW with 4K (3840 * 2160) screen with switchable graphics: (Intel HD Graphics 620 & Nvidia GeForce GTX960m).

My problem is that the windows animations are lagging (while maximizing or reopening the tab and opening start menu and especially while switching to the task view)

all of my graphic drivers are installed and up to date.

and I think it's related to My 4K resolution; Because I saw a lot of 4K screens (running at Windows 10) that they have the same problem.

but I had a laptop with a Full HD screen and I've never seen this problem at that.

and then I noticed when I change the resolution to 1080p, everything is very well, all of animations and effects are pretty smooth. This is interesting!

but I think the "Intel HD graphics 620" has the enough processing power and it can handle the Windows simple animations..! or is not Windows 10 compatible with 4K resolution. Am I right?

I thought this is related to Intel GPU Memory, then I have changed "Dedicated Video Memory" from 128MB to 512MB but It doesn't help.

I think this problem is only for who has switchable graphics (Intel HD Graphics with Nvidia or AMD).

because i saw many systems with one GPU (High-Performance GPU) and 4K resolution that they run Windows animations very smoothly

How I fix this problem? Is there a solution?

Sorry for my English, Thank you.

Hello AmirHossein Ahmadi,

I understand that Windows* animations lag when you are using the display at 4k resolution. Let me apologize for any inconvenience this issue may be causing to you. In order to help you better I would like to gather more information about the configuration you have in the computer. Please attach to this thread the .txt file the Intel® System Support Utility will generate https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility Please also attach the Intel Graphics Driver Report. This link will show you how to generate it https://www.intel.com/content/www/us/en/support/graphics-drivers/000005848.html https://www.intel.com/content/www/us/en/support/graphics-drivers/000005848.html Has it worked fine before? Was there any software or hardware change before the issue started happening? Let me also know if you are using the built-in display of the laptop or if you are using an external display. If you are using an external display let me know the type of video cable you are using. Regards,Fred D.
