***** Kernel New Kizzimo *****

The reg add commands add or modify values under the HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Control\Session Manager\kernel registry key:

KiClockTimerPerCpu and ClockTimerPerCpu set to 1:

These settings suggest enabling per-CPU clock timers, potentially allowing each
processor to handle its own timer interrupts.

KiClockTimerHighLatency and ClockTimerHighLatency set to 0:

These entries might be intended to disable high latency mode for clock timers,
aiming for quicker timer responses.

KiClockTimerAlwaysOnPresent and ClockTimerAlwaysOnPresent set to 1:

These settings could be intended to keep clock timers always active, possibly
preventing them from entering low-power states.

***** DWM Schedule MASTER VALUES *****

these were found using IDA (reverse engineering) so there is no official


documentation; what can be speculated though is...

WindowedGsyncGeforceFlag = 0
Disables G-Sync-like behavior in windowed mode on NVIDIA GPUs.

FrameRateMin = 0xFFFFFFFF
Removes minimum frame rate cap; allows full uncapped rendering.

IgnoreDisplayChangeDuration = 0
Prevents timing adjustments when display mode changes.

LingerInterval = 0
Eliminates delay between frame presents; may improve latency.

LicenseInterval = 0
Disables internal license check delays (possibly unused in retail).

RestrictedNvcplUIMode = 0
Unlocks full NVIDIA Control Panel UI options.

DisableSpecificPopups = 1
Suppresses internal popups (likely driver-related).

DisableExpirationPopups = 1
Suppresses licensing or feature expiration popups.

EnableForceIgpuDgpuFromUI = 1
Enables GPU switching from the UI (if supported).

HideXGpuTrayIcon = 1
Hides the tray icon used for hybrid GPU switching.

ShowTrayIcon = 0
Hides DWM-specific system tray icon.
HideBalloonNotification = 1
Suppresses notification balloons (like GPU or power hints).

PerformanceState = 0
Forces a lower/default DWM performance state.

Gc6State = 0
Disables deep GPU sleep state (GC6) — could stabilize responsiveness.

FrameDisplayBaseNegOffsetNS = 0xFFE17B80
Modifies the base offset in nanoseconds for vertical sync timing.

FrameDisplayResDivValue = 1
Divider for display timing — keeps at native resolution granularity.

IgnoreNodeLocked = 1
Bypasses GPU lock restrictions (may force use of otherwise inactive nodes).

IgnoreSP = 1
Likely disables Secure Presentation or overlay protection enforcement.

DontAskAgain = 1
Disables repeat confirmation dialogs in DWM/driver-related popups.
