When the Client Server Runtime process consumes excessive GPU, you may experience a sudden FPS drop when playing your favorite game. In the worst case, this may even freeze the computer, making your Windows experience severely degrade.
Basically, the Client Server Runtime (
cssrs.exe) is one of the vital Windows processes that manage the overall graphical subsystem and instruction sets. In normal conditions, its GPU usage is between 0% to 1%. But this may increase for various reasons, like enabling high graphics settings, corrupted drivers, viruses, etc.
Such a problem can occur anytime – when the OS is booting up, watching videos, playing games, or performing regular tasks. Nonetheless, you do not have to worry, as this can be easily solved.
