A recent Windows 10 update is trashing framerates and causing games to stutter

Might be worth a look'in if you have this update installed!

"I think I also have the same problem. Since yesterday when I upgraded Windows, my performance in Warzone has gone from 90 fps on average to 75 fps, even drops below 60 fps (V-Sync off)," yet another user wrote.

The common denominator in the various complaints is the installation of a cumulative update, including KB5001330 for Windows 10 version 2004 (20H1) then KB5000842 and finally KB5001337 for Windows 10 versions 1930 and 1909. .

Seems to be the same here too

" Hi Manuel, Yes, it seems recent windows updates introduced additional stuttering affecting some games. Not only KB you mentioned, but it is also included in newer one. Both KB5001330 19041.928 or 19042.928 and one you mentioned KB5000842 which is 19041.906 or 19042.906. If someone is on .928, then first he need to uninstall KB5001330, reboot, then KB5000842 will be restored if he had that update, so then he need to uninstall it. I can confirm that going back to 19042.899 feels more smoothly in games i play (world of warcraft, cyberpunk) "
After you uninstalled KB5001330>reboot> KB5000842

i think they are just the same update, the KB5000842 was an optional cumulative preview update, while the KB5001330 is the official release.
but yes, if u have installed both, uninstall both.

UPDATE :

Last month, Microsoft issued an update for Windows 10 that reportedly degraded performance on a number of PC systems. And a few days ago, the company released another update that resolves those gaming performance issues.

https://www.dsogaming.com/news/microsoft-has-fixed-the-recent-windows-10-gaming-performance-issues/

UPDATE 2 :

A small subset of users have reported lower than expected performance in games after installing this update. Most users affected by this issue are running games full screen or borderless windowed modes and using two or more monitors. " - Work around, This issue is resolved using Known Issue Rollback (KIR).

So basically instead of fixing it, it just rolls back to an older windows update? wtf That's what we've been doing lol

Have people got 2 or more monitors having this problem? I’ve only got one

It affects "fullscreen" "borderless" and people running more than one monitor

UPDATE :

John Papadopoulos - INDIERETRONEWS • 13 minutes ago

They fixed it by rolling back the thing that caused this issue (you will be still using the March 2021 Update). A more "proper" fix will most likely be included in the next big update.

This performance bug affects...

People with one monitor or an extra monitor
People who run full screen
People who run borderless

Microsoft has a fix for the gaming issues seen following the Windows 10 KB5000842 and KB5001330 updates.

The fix comes through Known Issue Rollback, which is a relatively new tool Microsoft uses to fix non-security updates.

Using the official fix should eliminate the issues without requiring people to uninstall an entire update.

Gamers on Windows 10 and some other users have run into issues following the KB5000842 and KB5001330 updates. People saw stuttering, inconsistent framerates, and other issues after applying the updates. While uninstalling the update could work around the issues before, Microsoft has now rolled out an official fix.

Important for O&O ShutUp10 users:

In SU10 you must undo/enable/red (slide to the left) the "Disable conducting experiments with this machine by Microsoft" option before hitting the [Check for Updates] inside Windows Update to receive the Known Issue Rollback (KIS).
If you do not do this, the registry key described in https://www.windowslatest.com/2021/...-windows-10-april-fix-for-performance-issues/ will not appear.
