NVIDIA 615.71.09 Linux Driver Released With Vulkan Improvements

# What happened NVIDIA released its Linux driver 615.71.09 (also referenced as R615). The update focuses on Vulkan improvements but also includes fixes affecting Wayland, multi-monitor power behavior, and kernel-driver capabilities.

# Why it matters This driver makes it easier for Vulkan-native games running under Proton to use NVIDIA Reflex low-latency features and brings several Vulkan and system-level fixes that can improve stability and reduce idle power usage in certain configurations. The release also expands kernel-driver features relevant to memory management for containerized or partitioned workloads.

# Major technical changes

• Vulkan additions: The driver includes VK_NV_low_latency revision 2, which enables out-of-the-box Proton support for NVIDIA Reflex when Vulkan-native games use NVIDIA's low-latency Vulkan library. It also adds support for VK_EXT_cluster_acceleration_structure and various other Vulkan driver fixes.

• Motion. It also resolves an Xid error that occurred when loading the PRAGMATA font on Wayland.

• Kernel driver option for power behavior: A new RmDisableDisplayGlitchPerfLimit kernel driver option is available to help reduce idle power consumption in some multi-monitor configurations.

• Memory partitioning: The release adds support for cgroups-based memory partitioning with NVIDIA's open kernel driver, bringing more flexible control over GPU memory allocation tied to cgroups.

# Practical implications for users If you run Linux gaming setups, especially with Proton or Vulkan-native titles, this driver should enable NVIDIA Reflex support without extra work and may resolve some input or latency-related workflows. Wayland users experiencing Smooth Motion or PRAGMATA-related crashes should see improved stability. Systems with multiple monitors that previously had elevated idle power usage can try the new kernel option to potentially lower idle draw.

Administrators managing GPU resources with containers or cgroups gain a new tool: cgroups-based memory partitioning support in the open kernel driver, which can help assign and limit GPU memory use by workload groups.

# Where to get it The Phoronix post points readers to NVIDIA.com for downloads and full release details.

# Bottom line 615.71.09 (R615) is a targeted maintenance and feature release focusing on Vulkan feature parity with Reflex support, fixing several Wayland/display issues, adding a kernel option for power behavior in certain multi-monitor setups, and enabling cgroups-based memory partitioning for the open kernel driver. Users with relevant workloads or issues should consider testing this driver and reviewing NVIDIA's release notes on their site.
