In keeping with their Game Ready Driver policy NVIDIA launched the GeForce 359.06 driver package on Monday evening, designed to give the best possible performance in both Just Cause 3 and Tom Clancey's Rainbow Six Siege. Unfortunately there were unforeseen side-effects for users equipped with certain mobile GPUs: in-game crashes and (in severe cases) the OS defaulting to CPU graphics. The GTX 860M (a mainstream GPU for gaming notebooks with a fairly large install base) was apparently affected, leading to something of an outcry on the official NVIDIA forums.

Thankfully NVIDIA have been pretty prompt in their turn-around for a hotfix and today issued the GeForce 359.12 driver package, a release which is intended to address the problems experienced by users of the mobile GPUs in question. As a hotfix driver it isn't WHQL certified, but if that's a necessity users can instead revert to GeForce 359.00. The hotfix is available from the NVIDIA customer support microsite, with separate downloads for both Windows OS versions.

Meanwhile the GeForce 359.06 driver package is still available from geforce.com/drivers or via the GeForce Experience app.
