Boost FPS & Fix Stutter – Optimize DirectX Shader Cache And GPU Overhead
Boost FPS & Fix Stutter – Optimize DirectX Shader Cache And GPU Overhead
Ever get random micro-freezes, shader stutter, or hitching mid-game even though your FPS looks fine? That’s often caused by bloated or corrupted DirectX shader caches and background compiler services.
The good news: you can fix this. In this video, I’ll show you 5 safe, reversible tweaks to clean shader caches, stop unnecessary background tasks, and optimize GPU cache behavior for smoother frametimes and less input delay.
🛠️ Commands & Paths Used
Step 1 – Purge DirectX Shader Cache
Run →
cleanmgr
✔ Select DirectX Shader Cache → Clean
Manual delete:
C:\Users\YourUser\AppData\Local\D3DSCache
Step 2 – Disable Shader Compiler Service
Run →
regedit
Path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\D3DShaderCache
Set Start → 4 (Disabled)
Revert: 2 (Automatic)
Step 3 – GPU Shader Cache Size
NVIDIA: Control Panel → Manage 3D Settings → Shader Cache Size → Set to 10GB or Unlimited
AMD: Radeon Software → Settings → Storage → Delete Shader Cache
Step 4 – Disable DirectX Telemetry Logging
Run →
regedit
Path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WMI\Autologger\EventLog-Microsoft-Windows-Direct3DShaderCache
Set Start → 0 (Disable logging)
Revert: 1 (Enable logging)
Step 5 – Clean Driver Shader Dumps & Crash Logs
Run →
%localappdata%
Delete inside folders:
NVIDIA\DXCache
AMD\DxCache
CrashDumps
Batch cleanup commands (CMD):
del /s /q "%localappdata%\NVIDIA\DXCache\*.*"
del /s /q "%localappdata%\AMD\DxCache\*.*"
del /s /q "%localappdata%\CrashDumps\*.*"
