GeForce 430.39 driver causes high CPU utilization, Nvidia releases fix

Nvidia GPU

Nvidia has released a new set of drivers for their GPUs, but gamers are reporting a pretty major issue with the new software update. The company released a new set of drivers, specifically the 430.39 GeForce drivers, which gamers immediately began to complain about. The original purpose was to improve support on a variety of titles for the new 1650 SKU which was just released, as well as adding seven new G-Sync Compatible monitors to the list of supported hardware:

  • ACER – KG271 BBMIIPX
  • ACER – XF240H BMJDPR
  • ACER – XF270H BBMIIPRX
  • AOPEN – 27HC1R PBIDPX
  • ASUS – VG248QG
  • GIGABYTE – AORUS AD27QD
  • LG – 27GK750F

The 430.39 drivers also aimed to handle a handful of bugs and other issues ahead of an upcoming Windows 10 update in a few weeks. So it looks like some issues with screen flickering and crash issues, especially with SLI enabled in some games, have been dealt with. The new patch did however introduce some major performance issues in a multitude of games, something that Nvidia quickly rectified.

Nvidia has released a Hotfix driver version 430.53 that corrects this issue. You can download the Hotfix here.

Here’s the full changelog for these patches and the hotfix if you want to see what’s happening with this most recent GPU update.
