While the release notes do not provide any specific details regarding both those security improvements or those specific optimizations for games, it does note that it comes with a new SLI profile which actually disables SLI in Titanfall 2. We suspect that the game optimization list includes games that were updated with earlier drivers, including Oculus Touch VR titles.
According to those same release notes, the new Geforce 376.33 Game Ready drivers also fix a couple of issues including the issue with the install of the Display Container via co-installer, corruption in Youtube video playback when two or more videos are playing at the same time in Chrome and clean up the escape calls that use physical addresses, under both Windows 10 and Windows 8.1/8/7 OS.
As always, the new Geforce 376.33 Game Ready drivers support all Nvidia Geforce graphics cards since Geforce 400 series days and is available for Windows 10, Windows 8/8.1 and Windows 7 OS in both 32-bit and 64-bit versions.
