The problem that was causing inaccurate GPU use statistics on Windows 11—typically on version 22H2—has finally been resolved by Nvidia. The most recent GeForce Game Ready WHQL-certified driver update, version 526.98, provides the patch.
Nvidia discovered that incorrect GPU use readings on their graphics cards were being caused by a problem in the Desktop Window Manager (DWM). Even when the system, and notably the graphics card, was almost idle, users claimed that the GPU use readings on Task Manager were consistently at or very close to 100%.
This DWM problem has been on the list of open issues for a time, therefore Nvidia has been working on it. As a temporary fix, the company had been advising users to disable Hardware-accelerated GPU Scheduling in Windows Settings.
In addition to this problem, Windows 11 22H2 systems have also been plagued by performance issues. Due to the large amount of reports from customers and reviewers, as well as the possibility that AMD Ryzen computers may potentially be affected, Microsoft only recently acknowledged the issue.
In addition to adding support for the new RTX 4080, the new GeForce 526.98 driver also fixes a DWM error and makes a number of new games Game Ready.
