It appears that the Nvidia Geforce 375.86 WHQL drivers released yesterday are plagued by a lot of issues including memory clock issues, Folding@Home, as well ass graphical problems in a couple of games.
According to user report from Nvidia Geforce forums, there are plenty of issues with the new Geforce 375.86 WHQL drivers, mainly memory clock issues on Geforce GTX 1080, GTX 1070 and GTX 1060 graphics cards.
Some users also report graphics issues with Call of Duty: Infinite Warfare as well as Battlefield 1.
It also appears that Folding@Home also has some issues, with the work being incorrectly calculated, while some users are also still reporting flickering issues on high refresh rate monitors, something that the Geforce 375.86 WHQL drivers should have fixed.
Unfortunately, there is still no new driver but Nvidia did promise that the fix will be coming soon. If you have installed the new Geforce 375.86 drivers, the best way is to roll back to the previous one.
