NVIDIA has published the release of a new branch of the NVIDIA proprietary driver 470.42.01, which is currently in beta testing. The driver is available for Linux (ARM, x86_64), FreeBSD (x86_64) and Solaris (x86_64).
Main innovations:
- Added initial support for OpenGL and Vulkan hardware acceleration for X11 applications running in Wayland environments using the Xwayland DDX component. According to the tests performed, when using the NVIDIA 470 driver branch, the performance of OpenGL and Vulkan in X applications launched using XWayland is almost the same as running under a regular X server.
- Implemented the ability to use NVIDIA NGX technology in Wine and the Proton package developed by Valve to run Windows games on Linux. Including Wine and Proton, you can now run games that support DLSS technology, which allows you to use the Tensor cores of NVIDIA video cards to realistically scale images using machine learning methods to increase resolution without losing quality.
The nvngx.dll library is included to use the NGX functionality in Windows applications launched with Wine. On the Wine side and stable releases of Proton, NGX support has not yet been implemented, but the inclusion of changes to support this functionality has already begun in the Proton Experimental branch.
- Added support for new GPUs: GeForce RTX 3070 Ti, GeForce RTX 3080 Ti, A100-PG506-207, A100-PG506-217, CMP 50HX.
- The limit on the number of concurrently running OpenGL contexts has been removed and is now limited only by the amount of available memory.
- Added support for PRIME technology to offload rendering operations to other GPUs (PRIME Display Offload) in configurations where the source and destination GPUs are handled by the NVIDIA driver, and when the source GPU is handled by the AMDGPU driver.
- Added support for new Vulkan extensions: VK_EXT_global_priority (VK_QUEUE_GLOBAL_PRIORITY_REALTIME_EXT, allows asynchronous reprojection in SteamVR), VK_EXT_global_priority_query, VK_EXT_provoking_vertex, VK_EXT_extended_dynamic_state2, VK_EXT_color_write_enable, VK_EXT_vertex_input_ dynamic_state, VK_EXT_ycbcr_2plane_444_formats, VK_NV_inherited_viewport_scissor.
- Using global Vulkan properties other than VK_QUEUE_GLOBAL_PRIORITY_MEDIUM_EXT now requires root access or CAP_SYS_NICE privileges.
- A new nvidia-peermem.ko kernel module has been added to allow RDMA to be used to directly access third-party devices such as Mellanox InfiniBand HCA (Host Channel Adapters) to NVIDIA GPU memory without copying data to system memory.
- By default, SLI initialization is enabled when using GPUs with different video memory sizes.
- nvidia-settings and NV-CONTROL provide cooler control tools by default for boards that support software cooler control.
- The gsp.bin firmware is included, which is used to move the initialization and control of the GPU to the side of the GPU System Processor (GSP) chip.
