Linux gamers running Direct3D 12 titles through Proton should see measurable improvements in frame pacing with NVIDIA's latest driver. The 615.78.08 release adds support for the VK_NV_low_latency2 revision 3 Vulkan extension, which directly benefits VKD3D-Proton by reducing latency and stutter, particularly when Frame Generation is enabled.
VKD3D-Proton translates Direct3D 12 API calls into Vulkan, making it a core component of the Steam Play/Proton stack for running Windows games on Linux. Frame Generation, which synthesizes intermediate frames to boost perceived smoothness, is especially sensitive to input latency. The low_latency2 extension exposes NVIDIA's Reflex technology through Vulkan, and revision 3 tightens its integration with frame interpolation pipelines, meaning fewer hitches in titles that lean heavily on D3D12 frame generation.
The driver also fixes blocky corruption in The Last of Us Part II and resolves a potential crash when displaying Vulkan HDR content under Wayland's color-management-v1 protocol. On the kernel side, NVIDIA now enables NVreg_UseKernelSuspendNotifiers=1 by default, handing video memory preservation during sleep and hibernation to the kernel automatically. A GPU page table allocation failure affecting tables larger than 2 GB has been fixed, along with a kernel module issue in certain SELinux configurations.
The driver is available now from NVIDIA's download portal.
