There’s a new Nvidia GeForce 375.86 driver out with day one optimizations for Steep and The Division - Survival, but you may want to hold off on downloading it if you’re a GeForce GTX 1080, GeForce GTX 1070, or GeForce GTX 1060 owner. A huge number of users are reporting the latest GeForce drivers break the memory speed of these graphics cards, leaving video memory stuck at just 810 MHz.
Buried away in the Issues and Updates section of the 375.86 driver is a little snippet which says "Some GTX 1080/1070/1060 GPUs video memory stuck at 810Mhz". Memory speed on the reference GTX 1080 is 1251 MHz, so you can see how this could potentially cripple performance at higher resolutions.
In addition to this, Battlefield 1 may flick while using multi-GPU in the latest update, as will Call of Duty: Infinite Warfare.
If you have already grabbed this driver then your best bet is to do a clean uninstall with DDU and reinstall an older driver. From the sounds of things if you don’t have a GeForce GTX 10 Series graphics card you should be able to download this latest driver without a hitch.
Which all really begs the question - why did Nvidia let this bug slip through the net for its latest and greatest graphics cards? It’s clearly aware of the issue; it’s right there in the driver notes. The glaring reason is a rush to get a day one Game Ready driver out as quickly as possible, but has the driver arms race finally come to bite Nvidia in the ass?
