NVIDIA released on 9 September 2026 the Linux driver 615.71.09, from the New Feature Branch<\/em>. For those who game on Linux with a GeForce GPU, the biggest change is the support for NVIDIA Reflex is the company's technology to reduce latency between input and the displayed image. In 615.71.09, the driver now provides The detail matters: it's not a promise of performance gain for every game, nor does it make any title compatible with Reflex. The game and its graphics pipeline need to use this interface. Still, it's a concrete step to bring the Vulkan gaming experience on Linux closer to what already exists on Windows.<\/p>\n Another novelty is support for memory partitioning based on cgroups<\/strong>. Cgroups are the Linux kernel mechanism used to organize and limit resources for groups of processes \u2014 a key foundation for containers and managed services. Phoronix associates this support with NVIDIA's open-source kernel driver. The release notes record the capability but don't document an administration interface for end users; for now, it's best treated as a driver foundation for future integrations, not a setting to copy into production today.<\/p>\n This version also adds the Vulkan extension Among the fixes is an Xid error 109 when loading PRAGMATA<\/em> on Wayland. The driver also includes the token Example from the official release notes to apply the token:<\/p>\n The 615.71.09 is the New Feature Branch<\/em> current, while NVIDIA maintains a Production Branch<\/em> separate (as of 9 September 2026, the latest production version is 595.99.02). On a workstation machine, prefer your distribution's package and read its changelog before switching branches. Avoid installing the file To check the version currently loaded:<\/p>\n If you use Proton and have a Vulkan game compatible with NVIDIA Reflex, the update is worth testing. For other cases, the best reason to migrate are the specific fixes that affect your setup \u2014 especially Wayland, Smooth Motion or multiple monitors.<\/p>\n Linux continues to receive relevant changes in the graphics stack, both in the proprietary driver and in the open-source drivers.

VK_NV_low_latency<\/code> revision 2. According to the official notes, this enables Reflex in Proton without additional driver configuration for games with native Vulkan rendering that use NvLowLatencyVk.dll<\/code>.<\/p>\nMore memory control for isolated workloads<\/h2>\n
VK_EXT_cluster_acceleration_structure<\/code>, fixes a file descriptor leak when unloading libGLX_nvidia.so.0<\/code> after vkDestroyInstance<\/code> and resolves startup crashes and window switching crashes when NVIDIA Smooth Motion is active.<\/p>\nWayland and multiple monitors<\/h2>\n
RmDisableDisplayGlitchPerfLimit<\/code>, added to the parameter NVreg_RegistryDwords<\/code> of the module nvidia.ko<\/code>. When applied, it can reduce idle power consumption in some multi-monitor configurations. NVIDIA itself warns that the parameter may alter memory clocks while the display is in use, potentially causing momentary visual glitches. This isn't a generic recommendation: only test if the power consumption issue is real and you have a straightforward way to revert the change.<\/p>\nmodprobe nvidia \"NVreg_RegistryDwords=RmDisableDisplayGlitchPerfLimit=1\"<\/code><\/pre>\nBefore updating<\/h2>\n
