FIX Input Delay And Reduce Input Delay - Timer Resolution + Registry Optimization
Does your game feel like it’s fighting against you? Shots a split-second late, mouse floaty, or inputs not locking in? That’s input delay – and today we’re going to crush it using Timer Resolution, ISLC, registry tweaks, and command-line fixes that pro gamers rely on.
No snake oil, no fake boosters — just proven tweaks for lower latency, smoother responsiveness, and stable frametimes.
🛠️ Commands & Paths Used
1. Timer Resolution Setup
Download → extract → run TimerResolution.exe
Right-click → Properties → Compatibility → Windows Vista
Run as Administrator
Click Maximum (forces 0.5ms resolution)
2. ISLC (Intelligent Standby List Cleaner)
Download from Wagnardsoft official site
Run as Admin → Settings:
Free memory is lower than: (Half of your RAM) e.g., 8000 MB for 16GB
Enable Custom Timer Resolution → 0.5ms
Hit Start → minimize to tray
3. Registry Edits
⚠️ Always backup first (Regedit → File → Export)
SystemResponsiveness
Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
Set SystemResponsiveness = 0
GPU Priority / CPU Scheduling
Path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games
GPU Priority = 8
Priority = 6
Scheduling Category = High
4. Command Prompt Timer Tweaks
Run CMD as Administrator → enter:
bcdedit /set useplatformtick yes
bcdedit /set disabledynamictick yes
bcdedit /deletevalue useplatformclock
Restart afterwards.
5. Automate on Boot
Startup Folder:
Press Win + R → type shell:startup
Drop ISLC or TimerResolution shortcut inside
Task Scheduler:
Create Task → Run with highest privileges → Trigger: At Log On → Action: Start ISLC.exe
Pro Gamer Batch Script:
start "" "C:\Path\To\ISLC.exe"
timeout /t 2
start "" "C:\Path\To\YourGame.exe"
Save as GameBoost.bat → shortcut on Desktop
