Trade-offs
Uses a little more memory.
Evidence
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.
Is it in a pack?
No. Packs never include tweaks with Limited evidence.
How to undo
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.
