Progress has been made in supporting NVIDIA graphics on Haiku OS, with the release of alpha driver packages that utilize NVIDIA's open-source kernel modules, NVK Vulkan, and Mesa's Zink driver, though support is limited to Turing GPUs and newer. The effort is still in early stages and not yet integrated into the main Haiku OS.
Development of Linux graphics drivers is progressing with early changes for Linux 6.20 or possibly Linux 7.0, including new buffer object synchronization features, improved GEM code, and the removal of support for the broken KDB debugger, with these updates queued for the upcoming merge window.
AMD's efforts to implement HDMI 2.1+ functionality in their open-source Linux graphics driver have failed, as the HDMI Forum has rejected their request for open-source driver support, leading to limitations such as the inability to provide 4K@120Hz and 5K@240Hz capabilities on the AMD Linux driver. This decision highlights the challenges faced by open-source initiatives in accessing now-private HDMI specifications, despite efforts by AMD and the X.Org Foundation to find a solution.
The Asahi Linux project has achieved OpenGL 4.6 conformance and OpenGL ES 3.2 support on the Apple M1, marking a significant upgrade for Linux OpenGL support on the platform. This development brings new capabilities such as SPIR-V support and compute shaders to Apple M1 devices running the Fedora-based Asahi Linux spin, with ongoing efforts to bring Vulkan API support and the AGX DRM kernel graphics driver upstreamed into Linux.
AMD has removed its latest graphics driver version after Valve warned that players using AMD's Anti-Lag+ technology would be banned under Valve's anti-cheat rules in games like Counter-Strike 2. Anti-Lag+ alters the game code itself, triggering bans and crashes in various competitive online games. Nvidia users have not reported similar issues with their Reflex system. Valve has acknowledged the unintentional cheating and will reverse bans once AMD releases an update.
Progress on NVK, the open source NVIDIA Vulkan driver developed by the community, is going well with support for Maxwell and Kepler GPUs, geometry, tessellation, and transform feedback, and more extensions. However, it's not yet passing the conformance tests and there's no timeline for when it will be upstreamed into Mesa directly. Work is ongoing on a new back-end compiler for NVIDIA hardware, and performance issues still need to be addressed.
Intel's latest Mesa 23.2 code has a significant performance optimization for its graphics driver stack, which helps Intel Arc Graphics DG2/Alchemist and upcoming Meteor Lake graphics. The change enables L3 partial write merging for compressible surfaces and other suitable cases for DG2 and Meteor Lake, leading to measurable speed-ups for Intel's Arc Graphics discrete GPUs and narrowing the gap between the Windows and Linux graphics driver performance. The change is currently in the Mesa 23.2-devel Git code and will be out as stable around late August or September.
Intel has submitted a final batch of feature updates for the "i915" Direct Rendering Manager driver to DRM-Next for staging ahead of the upcoming Linux 6.4 kernel merge window. The update includes continued Meteor Lake graphics enablement work, a new kernel module option to disable SAGV for debugging purposes, and various fixes for power management, DisplayPort MST, and high refresh rate PSR.
Valve has released an updated graphics driver for the Steam Deck OS, bringing Ray Tracing to DOOM Eternal. The update also includes fixes for graphical corruption issues in other games and a focus issue with Forza Horizon 5. The Steam Deck Beta Client has also been updated with fixes for icons, universal search, LAN peer downloads, and optimization for DualSense adaptive trigger effects.
