Nvidia driver bug could make your CPU work harder after closing the game News-thread

Nvidia released a new driver update for its GeForce graphics cards that, among other things, introduced a new Super video upscaling technology that could make low-resolution videos look better on high-resolution displays. But the driver (version 531.18) apparently also came with a bug that caused high CPU usage on some PCs after running and then closing a game.

Nvidia has released a driver review (version 531.26) which recognizes and should fix the problem, which was apparently caused by an undisclosed bug in the “Nvidia Wrapper”, a process that exists primarily to contain other processes that come with Nvidia drivers. It also fixes a “random bug check” issue that may affect some older laptops with GeForce 1000-series or MX250 and MX350 GPUs.

Not all PCs running the newer Nvidia drivers were affected by the error:some reporters observed the behavior in their systems, while others not. Even relatively low CPU usage in the 10 to 15 percent range can have a noticeable impact on performance, taking CPU cycles away from other tasks and preventing the CPU from going into an idle state. This generates more heat and uses more power and could also affect the battery life of laptops.

Other recent software bug in Nvidia drivers made games run slower when the Discord app was running in the background; an application profile issue was preventing the GPU memory from reaching its maximum clock speeds, lowering frame rates accordingly. This fix may be delivered silently in the background to PCs running Nvidia software, but installing the CPU usage fix requires you to download and install Nvidia’s typical 850MB driver package .
