Could you please let me know the driver versions you have tried?
In the meantime, please try updating your current driver version to the following; Download Intel® Graphics Driver [15.45]. Use this method for the installation; Manually Install an Intel® Graphics Driver in Windows® 10 and Windows....
I have tried multiple versions:
18.104.22.16864 - Official Acer driver
22.214.171.12444 - Windows update driver
126.96.36.19942 - Your recommended version
188.8.131.5252 - Beta driver
Sadly, none of them make any difference.
Thank you for that information.
From your system report I could not confirm if you have the latest Chipset Driver, so please try to get the latest from https://www.acer.com/ac/en/US/content/support-product/6403?b=1. Have you tried with VGA Driver .5937 from Acer?
Yes, I installed the chipset driver as early as i could after installing Windows.
Regarding the 10.18.13.5937 VGA driver from Acer, that is for the discrete Nvidia card, yes, I installed that one also from the beginning.
It since got updated to 184.108.40.20633 through the GeForce experience app.
I have exactly the same issue with my ASUS ZenBook-Pro UX501VW, which has exactly the same specification.
Performance, even for very basic usage like browsing, is absolutely atrocious when set to 4K. Everything is fine and silky smooth if I lower the resolution.
I have not. The logic behind my contacting Intel first, was the variety of manufacturers and configurations on which these problems are manifesting. Contacting Acer will be my next step.
However, can you please try to run the Excel test on a configuration similar to mine? I know this is a lot to ask, but if we're lucky you'll have all the data you need afterwards.
Contacting Acer, or me contacting ASUS would be pointless. The issue is clearly with the on-chip GPU implementation. Due to the fact that everything is fine at lower resolutions, most likely something is choking the GPU's bandwidth in some way. This could potentially be somewhat alleviated if Intel's driver devs work specifically with the aim of optimizing 4K performance.
I have an update. The Intel HD Graphics drivers updated automatically through Windows Update to version 220.127.116.1150. The problem still persists.
Edit: Not my best choice of words ... "update"
I made 2 videos describing my experience.
Intel HD Graphics 530 - Intel HD Graphics 530 performance in Excel. 4K resolution. - YouTube
Nvidia GTX960M - Nvidia GTX 960M performance in Excel. 4K resolution. - YouTube

Please give it a try, and let me now how it goes.
With the 4590 driver, performance seems to have improved a bit, but not significantly. The resize animations are still choppy.
