Surface Book 2 Task View Lag (and other high-resolution laptops included)

thanks for reply 。

I just hope next windows version will be ok 。

Ever since I got my Surface Book 2 (15 inch), Windows UI performance was quite sluggish. Windows framerate drops noticeably when opening Task View even with only one or two windows open, and switching desktop also experiences stutter. 

I tried to diagnose the issue myself, by installing latest drivers for UHD 620 graphics from both Microsoft and Intel. I tried reinstalling / uninstalling drivers for GTX 1060. None of these worked, and I have reinstalled Windows several times but nothing has changed.

However, one "solution" to this problem was to decrease the screen resolution to 1620*1080 @ 100% scaling, which mitigated the issue significantly. The usage of UHD 620 graphics is much lower (shown under graph labelled "3D") with lower resolution and animation became much smoother. Upon research I discovered that this issue is not specific to my device. Many other laptops with high resolution displays were experiencing the same problem.

Here are some links to thread discussing seemingly similar issue:

Laggy animations and effects at 4K resolution (running Windows 10)

Lag with Surface book 2

Is it that the Integrated Graphics Card in these laptops are not powerful enough to drive such a high resolution display? If so, the solution is not to lower the resolution as I did - that is just a poor excuse. Even my MacBook Pro Retina from 2012 performs better on MacOS than my Surface Book 2 does on Windows.

OR it is very likely that Windows 10 optimization on high-resolution laptops is just poor. It is ridiculous that such a high-end laptop experiences lag within its native OS only with few windows open; if Apple can do well with their animation on MacOS, there is no reason for Microsoft not to be able to do it.

Please look into this issue and fix it, Microsoft.

All the surface device has thisbissue. Also dell xps and what ever laptop have intel graphic card. Some leoptop have intel cacards disabled and no issues

I have a Surface Book 1 and I'm having similar performance issues.  It's *incredibly* frustrating to spend tons of money on this computer and have performance issues.  This is a Microsoft-built computer running Microsoft Windows!  You'd think Microsoft would make absolutely sure that their own OS would run flawlessly on their flagship computer.  But, no.  Honestly, this will keep me from recommending a Surface Book to anyone who asks.  I love the hardware, but the quirky performance issues are a real drag.  And the bugs...my god Microsoft, I'm uncovering new bugs with Windows 10 almost weekly.  And once Windows 10 seems OKish, Microsoft issues a new OS version with new bugs.  Then they come out with cumulative patches that are nothing but quality "improvements" to fix bugs.  Not sure what's going on with testing at Microsoft, but it's frustrating. 

That being said, my workaround to the UI issues has been to disable most Window visual effects:

1.  Hit Window key + R.

2.  Enter sysdm.cpl.

3.  Go to Performance.

4,  I selected "Adjust for best performance" and then added a few features back in.  Seems like getting rid of all of the "animations" and "fades" has improved things dramatically.

I still have my resolution at max (3000x2000 for Surface Book). There are some minor lags, but it's much better.  Knocking down my resolution does the trick too but the screen's not nearly as clear when I do that.  I prefer running full resolution with minimal visual effects.

after install latest update, looks like my problem solved.

Hi Leoyangad,

Do you mean this update:

https://support.microsoft.com/en-us/help/4343897/windows-10-update-kb4343897

I have this installed and nothing's changed for me.  Or is there a display driver update or something else you installed?
