Nvidia's latest graphics drivers have been the subject of many introductions – including support for the GeForce GTX 16-Series notebooks (and the new GTX 1650 desktop card) – but it seems that version 430.39 has also brought a pretty nasty bug that increases CPU usage on Windows.
A number of users reported seeing their CPU utilization increase by approximately 10% to 20%, even when the PC is idle and no game (or anything else) is running .
Manuel Guzman, head of software quality at Nvidia, and still active on the official bug removal forums, explained the problem as follows: "We have been able to reproduce the bug consistently now and we are currently testing a patch.
Apparently, this has something to do with the Nvidia Display Container LS (local system), which, according to a Reddit user, "is constantly monopolizing 10% of CPU usage, even in idle without anything going on. (As indicated by Windows Latest). The reboot temporarily fixes the problem, but it comes back soon enough, from all accounts.
Another user commenting on the Nvidia forum said: "We are hoping soon to find a solution to the intensive use of the processor for NV Container LS. I use 17% CPU in the background for no reason on my 8700K [processor] is getting old. "
The wickedness of notebooks
This is obviously bad news for everyone concerned because no one wants their CPU cycles to be used for no reason, but this will particularly annoy laptop users whose battery will be affected by this extremely irregular processor activity . In other words, you can get support for the new GTX 16-Series mobile GPUs with these latest drivers, but potentially your processor may not be as well taken into account …
There is not yet an official solution or a workaround, but as we have already mentioned, Nvidia is currently working on a solution, and we hope it will not be too long.
This is obviously a thorny problem for Nvidia, because we found that the problem had already been mentioned in February 2019 with the driver version 419.17. Some users of this old thread actually said that 30% of CPU usage was affected, including a GeForce owner who deplored the bug back in the current drivers.
It should also be noted that the new 430.39 drivers introduce support for the impending update of Windows 10 May 2019 and fix a persistent bug that caused random desktop flickering for some users running multiple monitors.
