Terrible stutter and 100%GPU utilisation when playing low-res videos full screen

[dgtal1]

Hi all,

I've got an issue when playing videos. They stutter a lot on my Windows 11 Lenovo ThinkBook powered by i7-1255U CPU with Irisx graphics.  This applies to Windows Media Player, Google Chrome, Whatsapp Desktop and other software.

I noticed a pattern - this mostly happens when playing low-res videos full screen. E.g. When I watch YT video in 720p or lower it stutters a lot. When I switch to FHD or 4K - the stutter is gone. It's like the laptop is not able to handle upscaling for full screen.  4 CPU cores are 100% utilized then and the GPU 3D function is utilized in 100% as well in Windows Task Manager.

There's something wrong and I think can't be related to weak hardware as my 10 yrs old Windows 10 PC based on 4th gen i5 can handle this without any issues...

Can you suggest some fixes?

Hello dgtal1,

Regarding to your inquiry, you can try performing driver update for your Lenovo Thinkbook.

Try updating your driver using your OEM website, which is Lenovo, if the issue persists.

You can also try updating using Intel website for your Intel Iris Xe graphics, here is the link for the driver: Intel® Arc™ & Iris® Xe Graphics - Windows*

Let me know if this works.

Hello Eric,

Thank you for your reply. I've found the root cause. It's Lenovo's "Super Resolution" feature controlled by the Lenovo Vantage app. It's "on" by default. I disabled it and all my issues are gone now. All videos play normally without any stutter or lagging.

Lenovo has no driver updates atm unfortunately. I think it's some buggy implementation of this feature as I can' believe modern hardware isn't able to upscale lo-res videos to FullHD.

I've filed feedback to them, altough they sem not to be interested. Maybe you have some means to contact them about it as from user perspective it seems it's a faulty intel's hardware (GPU load = 100% + high CPU load)
