Microsoft recently released monthly update KB5005033 to Windows 10 versions 21H1, 20H2 and 2004. The update brings improvements targeted at fixing PrintNightmare vulnerability by making admin privilege necessary to install drivers.
But the update may be causing Gaming performance issue for some users. More than one user complained about facing Gaming performance issue after installing this update in a Reddit thread.
One Redditor complains about gaming performance tanking after installing the update while another confirms stuttering issue while gaming after the update. Microsoft has fixed gaming performance issue in a recent Windows 10 update. So, it will be interesting to see whether the gaming issue reported after installation of update KB5005033 is a new one or the old one still existing.
