Valorant: Best Windows Registry Tweaks for Lower Input Latency

The primary goal for Valorant registry optimization is Interrupt Moderation and Priority Scheduling. Windows is a multi-tasking OS that often puts background services on the same level as your game. These tweaks focus on the Multimedia Class Scheduler Service (MMCSS) and Power Throttling to ensure that Valorant’s network and input packets are processed with absolute priority.

Hardware & Safety Prerequisites

• Backup Your Registry: Before making changes, open regedit, go to File > Export, and save a backup of your current registry.
• System Restore Point: It is highly recommended to create a system restore point.
• Windows Version: These tweaks are compatible with Windows 10 and Windows 11 (22H2/23H2 and later).

Registry Path & Technical Configuration

Below are the most effective registry keys for lower input latency. You can navigate to these paths manually in regedit.exe.

1. Game Priority & Scheduling

This tweak tells Windows that “Games” should have the highest priority for the CPU.

Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games

Value Name	Data (Hex)	Impact
GPU Priority	8	Increases GPU scheduling priority for games.
Priority	6	Sets the CPU task priority to “High.”
Scheduling Category	High	Ensures the kernel doesn’t delay game threads.
SFIO Priority	High	Prioritizes disk/I/O operations for game assets.

2. Disabling Network Throttling

Windows often throttles non-multimedia network traffic to save resources. We want this disabled for Valorant’s sub-tick communication.

Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile

• Value: NetworkThrottlingIndex
• Data: ffffffff (Hex) — This disables throttling entirely.

3. Disabling Power Throttling (Vanguard Friendly)

This prevents Windows from putting Valorant into a “low power” state when it’s running in the background or during Alt-Tabs.

Path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerThrottling (Note: If the “PowerThrottling” key doesn’t exist, create it.)

• Value: PowerThrottlingOff
• Type: DWORD (32-bit)
• Data: 1

Strategy for Lower Input Latency

To maximize the “snappiness” of your mouse (Aimpunch):

• Interrupt Affinity Policy: While not a direct registry edit, using the MSI Mode Tool (Message Signaled Interrupts) to set your GPU to “High” priority works in tandem with these registry tweaks. It ensures the GPU doesn’t have to wait for “Legacy Interrupts” from other hardware like your sound card.
• FSO (Fullscreen Optimizations): While Valorant usually handles this well, ensuring the registry key for GameDVR_Enabled is set to 0 at HKEY_CURRENT_USER\System\GameConfigStore prevents the Windows “Game Bar” overlay from adding an extra layer of frame-buffer latency.
• USB Polling Stability: If you use an 8000Hz mouse, ensure you are not using “USB Power Savings” in the registry, as the rapid wake/sleep cycles can cause micro-stutters during micro-adjustments.

Key Performance Parameters

Registry Feature	Recommended Setting	Impact
NetworkThrottlingIndex	ffffffff	Eliminates artificial packet delay.
GPU Priority	8	Reduces frame-time variance (Stuttering).
Win32PrioritySeparation	26 (Hex)	Optimizes CPU time-slices for foreground apps.
PowerThrottlingOff	1	Prevents the CPU from downclocking during play.

Conclusion and Expected Results

By manually refining your Windows Registry to prioritize game tasks and disable power-saving interrupts, you are stripping away the “bloat” of a general-purpose OS. You can expect more consistent frame times, sharper mouse response, and the removal of micro-stutters during high-utility executes on sites.
