IzanagiOP Precision Packs explained: Trajectory, Spread, Scatter, HitSync

#gaming #windows #performance #showdev

IzanagiOP includes specialized "Precision Packs" — groups of tweaks targeted at specific in-game behaviors. Here's what each one actually changes.

Trajectory Pack

For sniper accuracy and click-timing precision. Changes:

Raw 1:1 mouse input: removes SmoothMouseXCurve and SmoothMouseYCurve, sets MouseSpeed/Threshold to 0
Foreground lock timeout = 0: game window takes focus instantly on click
Cursor shadow off: minor DWM overhead reduction
Snap to default button off: prevents unwanted cursor jumps
Per-game CPU/IO/GPU priority via IFEO: for CS2, Valorant, FiveM, Fortnite, Apex, OW2, LoL, Roblox, Arc Raiders
DXGI MaxFrameLatency = 1: render queue to 1 frame
NIC tuning: Energy Efficient Ethernet off, Wake on Magic Packet off

For sustained fire (automatic weapons, rated-fire patterns). Changes:

CPU core parking off: no core spin-up delay mid-spray
Min/max CPU frequency locked to 100%: sustained clock during spray
P-core preference: HeterogeneousSchedulingPolicy=4 on hybrid CPUs
EcoQoS off: no power throttling mid-game
Kill ~10 non-essential services: DiagTrack, WerSvc, SysMain, WSearch, Spooler, AppReadiness, PcaSvc, TabletInputService, GameDVR, OneDrive

For network-dependent gunplay (shotguns, burst fire with high server ping sensitivity). Changes:

For timing-sensitive interactions (server-side hit registration). Changes:

MMCSS full suite: Games Priority=6, Audio Priority=6, SystemResponsiveness=0
NoLazyMode=1: scheduler always active
Timer resolution: GlobalTimerResolutionRequests=1, disabledynamictick=yes
NTP poll interval: 120s (more frequent clock sync)
Win32PrioritySeparation = 38
TSC sync: Enhanced mode via bcdedit
