Game Ready
Provides the optimal gaming experience for BattleTech and FrostPunk.
New Features
NVIDIA RTXTM Technology
Developer preview for NVIDIA RTX ray tracing technology for DirectX 12. NVIDIA
RTX supports the Microsoft DirectX Raytracing (DXR) API on NVIDIA Volta GPUs.
In order to get started with developing DirectX Raytracing applications accelerated by
RTX, you'll need the following:
• NVIDIA Volta GPU
• NVIDIA driver version 396 or higher
• Windows 10 RS4
• Microsoft's DXR developer package, consisting of DXR-enabled D3D runtimes,
HLSL compiler, and headers
Vulkan 1.1
This driver release provides full support for the new Vulkan 1.1 API and passes the
Vulkan Conformance Test Suite (CTS) version 1.1.0.3.
HD Audio
This driver adds new sample rates 32 kHz, 88.2 kHz, and 176.4 kHz to the HDMI
device for all GPUs.

Chapter 2 : RELEASE 396 DRIVER CHANGES
Display Driver Standalone Installer
The standalone display driver installer now removes extracted files after installing the
driver, leaving a smaller footprint on the hard drive.
Display Driver Libraries
Added new libraries (nvdlist.dll and nvdlistx.dll) to support Optimus and MSHybrid
notebooks.
NVDECODE API
Added a new API that lets the client reconfigure the decoder resolution and other post
processing parameters (such as the display resolution, cropping rectangle, and aspect
ratio of the decoded frame) without having to destroy and recreate the decoder
instance. This API is useful in scenarios where the decoder instance initialization time
takes up a significant portion of the overall decode execution time; for example, in
back-to-back decoding of multiple short clips of different resolutions.
The new API will be included in Video Codec SDK 8.2, which is expected to release in
late Q2 2018.
Application SLI Profiles
Added or updated the following SLI profiles:
• Descenders
• Frostpunk
• Warhammer: Vermintide 2
• Far Cry 5
3D Vision Profiles
Added or updated the following 3D Vision profiles:
• Descenders - Good
• EVE Valkyrie - Warzone - Good
Software Module Versions
• nView - 148.92
• HD Audio Driver - 1.3.37.1
• NVIDIA PhysX System Software - 9.17.0524
• GeForce Experience - 3.13.1.30
• CUDA - 9.2
And here are the known issues :
Windows 10 Issues
[Microsoft Edge][HDR] With HDR turned ON, video playback in full-screen mode on
an HDR display may cause corruption of the video and desktop.
To recover, manually turn the monitor OFF and then back ON. A future driver
[Far Cry 5]: Green flickering occurs in the game when using HDR with non-native
resolution.
To work around, either quit and then restart the game while in the desired resolution, or press
[Alt+tab] away from and then back to the game, or press [Alt+Enter] to switch to windowed
mode and then back to full-screen mode.
[NVIDIA TITAN V][G-Sync]: G-Sync displays may go blank when switching between
different overclocked memory clocks multiple times. [200361272]
[SLI][GeForce GTX 780 Ti]: There is no display output when connecting the
DisplayPort and two DVI monitors. [1835763]
[GeForce TITAN (Kepler-based)]: The OS fails after installing the graphics card on a
Threadripper-enabled motherboard. [1973303]
[Pascal GPUs][Gears of War 4]: Blue-screen crash may occur while playing the game.
[2008731]
[GeForce GTX 1080 Ti]{Warhammer Vermintide 2][DirectX 12]: TDR errors may occur
when changing resolutions in game. [200395335].
To work around, use the DirectX 11 game option.
[NVIDIA Control Panel][Surround]: NVIDIA Surround hot keys do not work.
[200394749]
[GeForce Experience][ShadowPlay]: The “In-Game Overlay” option cannot be
enabled, nor does Shadowplay recording work. [200390642]
The Microsoft Media Foundation library must be installed in order to use these features. Be
sure to first install the Media Foundation package.
