This utility allows your hardware—like your , network adapter, and USB controllers—to communicate directly with the CPU.

: Do not enable MSI mode for devices that do not explicitly list it as a supported mode, as this can cause system instability or boot failures.

: You can find the latest version on the Sathango GitHub repository or from the Guru3D forums.

: Before applying changes, it is highly recommended to create a System Restore Point.

: You must restart your computer for the changes to take effect. Important Safety Note

: Check the box under the MSI column for your GPU, set the priority if desired, and click Apply .

: By switching from older "line-based" interrupts to MSI mode, devices no longer have to share communication lines, leading to lower input lag and smoother frame rates.
