Windows 10 patch breaks Destiny 2 along with other games on some PCs

A brand new cumulative update for the latest version of Windows 10 is playing havoc with gaming performance on some users’ PCs, a minimum of going through reports online.

The patch in question is KB4482887 for Windows 10 October 2018 Update, which was very recently unleashed to provide a lot of fixes, including enabling ‘Retpoline’ which should improve the performance of PCs by mitigating any sluggishness caused by the Spectre variant 2 fix.

However, rather ironically, the update seems to have had the opposite effect for some in a few games, delivering a big performance hit – even though this might not have anything to use the Retpoline fix (more on that later).

Multiple threads have put their hands up on Reddit describing performance issues primarily with Destiny 2, but also with other games.

One commenter asserted their mouse settings felt wrong, plus they were getting ‘much less’ than 60 frames per second in Destiny 2 on a seriously powerful rig with twin SLI RTX 2080 Ti graphics cards. Uninstalling the KB4482887 update fixed the problem (which apparently affects both Nvidia and AMD GPUs alike).

There are multiple reports of significant Destiny 2 woes along these lines, and the other Reddit thread observed “massive lag spikes in older games, like CoD4 and CoD MW2” and hugely laggy mouse performance. Again, these issues disappeared after uninstalling the update (and came back if it was reinstalled).

Feed it back

Chipping in on the former Reddit thread, a Microsoft employee said: “This is probably not associated with Retpoline (Spectre mitigation) since it’s not enabled for retail users yet (by 3/4/2019).” The Microsoft staffer then urged anyone with gaming-related performance issues to submit feedback (providing a link which appears to be broken, however, you can use the feedback hub).

Note that the state response isn’t certain about this being unrelated to the Retpoline fix, but we all do realize that the second is being deployed gradually like a phased rollout, so may not actually be survive a lot of PCs yet.

However, perhaps those experiencing issues could be the “certain devices” that Microsoft noted the Retpoline fix has gone reside in these initial stages of deployment. Still, the Microsoft employee clearly believes that any gaming performance hit probably isn’t related.

Anyway, the takeaway for now is to dump KB4482887 (or avoid installation to begin with) if you’re experiencing sluggishness with Destiny 2 or other games on Windows 10 October 2018 Update.

Hopefully we’ll learn more about the exact real cause, and hopefully a resolution to the aforementioned issues, before too long.
