NVIDIA 565.57.01 Beta has Wayland and HDR improvements, plus DXVK and VKD3D optimizations

NVIDIA today released two new Linux drivers. The big one is the NVIDIA 565.57.01 Beta, along with a one-liner update in the stable 550.127.05 release.

The stable release driver 550.127.05 mentions "Fixed a bug which could cause applications using GBM to crash when running with nvidia-drm.modeset=0".

While the bigger NVIDIA 565.57.01 Beta includes various new features and fixes I've split below for easy reading.

New Features & Improvements

• Re-enabled GLX_EXT_buffer_age on Xwayland. This extension had been previously disabled on Xwayland due to a bug which is now fixed.
• Added support for mmap of exported DMA-BUF objects.
• Added several new per-plane and per-CRTC vendor-specific properties to nvidia-drm. These properties may be used by Wayland compositors to program the GPU's color pipeline for HDR hardware acceleration.
• Introduced a driver optimization to mitigate the performance loss from the 'd3d9.floatEmulation' option in DXVK.
• Updated the framelock settings page of the nvidia-settings control panel to use the GTK3 theme text color rather than defaulting to white for the text color, improving legibility with some themes.
• Implemented support for VK_EXT_depth_clamp_control.
• Reduced some cases of stutter with OpenGL syncing to vblank while using GSP firmware.

Bug Fixes:

• Fixed a bug that could cause suspend/resume to fail when using the NVreg_PreserveVideoMemoryAllocations option: https://github.com/NVIDIA/open-gpu-kernel-modules/issues/472
• Fixed a bug that caused the cursor image to be truncated on Gamescope: https://github.com/ValveSoftware/gamescope/issues/1099
• Fixed a bug that caused FarCry 5 running through DXVK to display a black screen.
• Fixed some performance regressions that were observed with Vkd3d 2.9.
• Fixed a bug that could cause flickering in some applications when using Unified Back Buffer (UBB).
• Fixed a bug which could cause incorrect and/or washed out colors to be displayed with HDR scanout: https://bugs.kde.org/show_bug.cgi?id=482780
• Implemented support for VK_EXT_depth_clamp_control.
• Fixed a bug which could cause applications using GBM to crash when running with nvidia-drm.modeset=0.
• Fixed a bug that could cause kernel crashes upon attempting KMS operations through DRM when nvidia_drm was loaded with modeset=0.
