Release highlights since 346.47:
- Added support for G-SYNC monitors when used together with non-G-SYNC monitors. When G-SYNC is enabled, non-G-SYNC monitors will display with tearing.
- Fixed a bug that caused nvidia-settings to crash when assigning an attribute whose value is a display ID on a system with multiple X screens.
- Updated the reporting of in-use video memory in the nvidia-settings control panel to use the same accounting methods used in other tools such as nvidia-smi. nvidia-settings was not taking some allocations into account, e.g. framebuffer memory for the efifb console on UEFI systems, causing discrepancies in the values reported by different tools.
- Removed the "EnableACPIHotkeys" X configuration option. This option has been deprecated and disabled by default since driver version 346.35. On modern Linux systems, display change hotkey events are delivered to the desktop environment as key press events, and the desktop environment handles the display change by issuing requests through the X Resize and Rotate extension (RandR).
- Added support for lossless H.264/AVC video streams to VDPAU.
- Added support for VDPAU Feature Set F to the NVIDIA VDPAU driver. GPUs with VDPAU Feature Set F are capable of hardware-accelerated decoding of H.265/HEVC video streams.
- Fixed a bug that prevented GPU fan speed changes from getting reflected in the text box on Thermal settings page.
- Added nvidia-settings commandline support to query the current and targeted GPU fan speed.
- Added a checkbox to nvidia-settings to enable a visual indicator that shows when G-SYNC is being used. This is helpful for displays that don't indicate themselves whether they are operating in G-SYNC mode or normal mode.
This setting can also be enabled by running the command line
nvidia-settings -a ShowGSYNCVisualIndicator=1
- Added support for the X.Org X server's "-background none" option. When enabled, the NVIDIA driver will try to copy the framebuffer console's contents out of /dev/fb0. If that cannot be done, then the screen is cleared to black.
- Added support for YUV 4:2:0 compression to enable HDMI 2.0 4K@60Hz modes when either the display or GPU is incapable of driving these modes in RGB 4:4:4. See NoEdidHDMI2Check in the README for details.
- Fixed a bug that could cause multi-threaded applications to crash when multiple threads used the EGL driver at the same time.
- Fixed a bug that caused Sync to VBlank to not work correctly with XVideo applications in certain configurations.
- Fixed a bug that prevented the X driver from correctly interpreting some X configuration options when a display device name was given with a GPU UUID qualifier.
- Fixed a bug that artificially limited the maximum pixel clock on displays in some SLI Mosaic configurations.
- Fixed a kernel memory leak that occurred when looping hardware-accelerated video decoding with VDPAU on Maxell-based GPUs.
- Fixed a bug that could cause nvidia-settings to crash on exit on 32-bit Linux systems.
