Vulkan Runtime Libraries 1.0.39.1 Instant

The Vulkan Runtime Libraries themselves are inert unless an application calls them. They do not run as a background process consuming CPU or RAM when no game is active. Therefore, .

For end users, 1.0.39.1 is obsolete but harmless. For developers, it is a historical artifact, useful only for legacy testing.

| | Action | |------------------|-------------| | You have a modern GPU (GTX 10-series or newer, RX 400-series or newer, Intel 8th gen or newer) and keep drivers updated. | Uninstall 1.0.39.1 safely. Your newer Vulkan runtime (1.2+) handles everything. | | You have an older GPU that just barely supports Vulkan 1.0, and newer drivers are no longer available. | Keep 1.0.39.1. It may be the only working Vulkan runtime for your system. | | You are unsure if any app needs Vulkan. | Leave it. Storage space is cheap (under 200 MB). Removing it risks breaking games without meaningful gain. | | You see high CPU/GPU activity from vulkan-1.dll and suspect malware. | Verify the digital signature. If invalid, run a full antivirus scan (Windows Defender suffices). If valid, the issue lies elsewhere. |
