Sebastian Castellanos posted on X about a big performance drop with the Nvidia App installed in both Black Myth: Wukong and The Talos Principle 2.
There has been a claim that the Nvidia App could reduce performance by up to 15%, but the Nvidia App isn't to blame.
It just has nothing to do with the Nvidia App installed, but it’s the Nvidia overlay. The overlay is causing the performance drop.
When stories like this break, there’s a mad dash to verify (or refute) claims that are circulating online, and the testing during that dash is generally limited, and sometimes, short-sighted.
Even with the Nvidia App installed, performance can go right back up to where it was with the app uninstalled if you disable the Nvidia overlay.
Having the Nvidia App installed will let you know when new drivers come out. And new drivers will improve your performance, particularly in new games.
The advice coming out of this story has been to just uninstall the Nvidia App if you aren’t using the additional features available in it.
Performance drop can vary depending on the app version, Windows version, driver version, and of course, your PC hardware itself.
There’s general understanding that additional apps running on your PC will take some of your system resources.
If you enable the Nvidia overlay the first time you install the Nvidia App, it stays enabled, even if you never pull it up.
