GeForce 397.31 – RayTracing & 64 bit

GeForce GTX logo

Come anticipato qualche tempo fa, la nuova serie di driver per schede video NVIDIA GeForce è solo 64 bit. L’azienda di Santa Clara era rimasta l’ultima a proporre driver a 32 bit anche per le architetture più recenti, dopo che Intel e AMD hanno smesso di supportare le architetture più recenti – AMD aggiorna ancora i driver 32 bit, ma solo fino alle Radeon serie 200.

Ma la novità principale di questa nuova serie 396 (denominazione interna) riguarda il supporto in anteprima a RTX, la tecnologia NVIDIA per il ray tracing, nonché il supporto a Vulkan 1.1 e una serie di migliorie minori ma non per questo poco importanti. ATTENZIONE: Con alcune GeForce 1060 il driver può fallire l’installazione mostrando il codice errore 43 dopo il riavvio del sistema. L’errore è riconosciuto da NVIDIA, che sta lavorando per correggerlo nella prossima release dei driver.

NVIDIA RTX 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.

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.

Fixed Issues in this Release

  • [GeForce GTX 1080 Ti][Doom]: The game crashes due to the driver reverting to OpenGL 1.1 when HDR is enabled. [2049623]
  • [GeForce GTX 1060][Far Cry 5]: The game crashes after a few minutes of game play. [2096077]
  • NvfbcPluginWindow temporarily prevents Windows from shutting down after launching a Steam game. [2068833]
  • [Firefox]: Driver TDR error may occur when using Firefox. [2049523]
  • [GeForce GTX 1060][Rise of Tomb Raider]: Flickering/corruption occurs when opening the in-game options UI. [200351146]
  • [NVIDIA Control Panel][SLI][Diablo III]: With V-Sync on and SLI enabled, the game freezes after switching windows (ALT+TAB) a few times. [1951584]

Open Issues in Version 397.31 WHQL

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.
