Nvidia fixes a weird GPU driver bug that tanked CPU performance

Nvidia’s GPU driver was recently found to have a bug that was spiking processor usage after quitting out of a game, but the good news is this problem has been fixed in a freshly released hotfix.

Neowin reports that the affected GeForce driver version, 531.18, now has a hotfix (531.26), and it cures two issues including the gremlin that was eating CPU resources.

This was an odd bug which saw an Nvidia Container process hang around after you’d stopped playing a game and exited. Going into Task Manager, gamers were seeing CPU resources being eaten up to the tune of 10% or even 15%, causing some slowdown to the host gaming PC.

If you didn’t open Task Manager and notice this process, then manually close it, your machine could run rather sluggishly and you’d have no idea why.

Still, the cure has arrived now, and if you were holding off updating to version 531.18 due to the presence of this bug, you can now go ahead.

Analysis: Notebook crashing blues also fixed

This fix has been deployed quickly, which is good to see. Nvidia chose the route of a hotfix because that can be pushed out immediately to those with GeForce graphics cards, rather than having to wait for a cure bundled with the next version of Team Green’s graphics driver.

The hotfix also comes packing a resolution for a second problem. Namely a random crash (stop error) happening with some laptops that have GeForce GTX 10 Series, or MX 250 / MX 350 mobile GPUs.

Both of these are quite nasty little glitches, so it’s good to see them stamped out by Nvidia in a swift manner. Indeed, because there was apparently some noticeable slowdown evident with the persisting Nvidia Container bug, slightly more paranoid types may even have wondered if something had happened malware-wise, as sudden system slowdown or lack of responsiveness can be a symptom of infection – so they may have worried unduly.
