MSI interrupt mode for the GPU

(per-device values resolved on this PC)

Before anything is written, the review screen shows this setting's current value on your PC next to the new one.

Can reduce interrupt latency where a GPU still uses line-based interrupts. Most modern GPUs already use MSI.

If a device misbehaves after restarting, restore this change (Safe Mode works too). Create a restore point first.

Limited evidence means: popular, but gains are rarely measurable. Expected impact is small (1 of 3): how much it can matter when this is actually the bottleneck on your PC, not a promised gain.

Gains from this tweak are rarely measurable on modern Windows, so it is never recommended or applied in bulk. If you try it, measure before and after with the Benchmark and keep it only if it helps.

No. Packs only contain Safe tweaks, and this one is labelled Experimental.

Switch the tweak off in Nexus, or open Restore Center and restore this change (or choose Undo last change). Nexus writes back the original value it recorded before applying, not a generic default, then reads it back to confirm.

Like applying it, undoing it takes full effect after you restart.

• Network adapters that support this setting; values are read from your active adapter.

Anywhere else, Nexus shows it as not applicable instead of pretending it works.
