GPU

Optimization Category

Hardware-Accelerated GPU Scheduling

Medium

Reduces latency by allowing GPU to manage its own memory

💡 Lower GPU latency, improved frame times in games and 3D applications

Enable GPU Scheduling

This registry setting enables hardware-accelerated GPU scheduling (Windows 10 2004+). Value: 1=Disabled, 2=Enabled (recommended)
PowerShell / CMD
New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\GraphicsDrivers" -Name "HwSchMode" -PropertyType DWord -Value 2 -Force

Note

ℹ️
Requires Windows 10 build 2004 or later. May require driver updates for optimal compatibility.

Timeout Detection and Recovery (TDR)

Medium

TDR restarts GPU driver if it detects a timeout. Adjust for gaming performance

💡 Prevents driver timeouts during intensive GPU tasks

Increase Timeout to 10 Seconds

Increases TDR timeout delay for GPU-intensive operations
PowerShell / CMD
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\GraphicsDrivers" New-ItemProperty -Path $path -Name "TdrDelay" -PropertyType DWord -Value 10 -Force

Disable TDR (Not Recommended)

Completely disables TDR. Only for advanced users.
PowerShell / CMD
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\GraphicsDrivers" New-ItemProperty -Path $path -Name "TdrLevel" -PropertyType DWord -Value 0 -Force

TDR Warning

⚠️
Disabling TDR completely can cause permanent black screens if driver freezes. It is safer to increase timeout with TdrDelay instead.

Nvidia - Maximum Performance

Medium

Configure Nvidia GPU for maximum gaming performance

💡 Improved GPU performance and reduced power management overhead

Enable Maximum Performance Mode

Sets Nvidia GPU to maximum performance level with power management disabled
PowerShell / CMD
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000" New-ItemProperty -Path $path -Name "PerfLevelSrc" -PropertyType DWord -Value 8738 -Force New-ItemProperty -Path $path -Name "PowerMizerEnable" -PropertyType DWord -Value 0 -Force New-ItemProperty -Path $path -Name "PowerMizerLevel" -PropertyType DWord -Value 1 -Force New-ItemProperty -Path $path -Name "PowerMizerLevelAC" -PropertyType DWord -Value 1 -Force

Disable Preemption

Disables GPU context preemption for better frame consistency
PowerShell / CMD
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Scheduler" New-ItemProperty -Path $path -Name "EnablePreemption" -PropertyType DWord -Value 0 -Force

Advanced Tuning

ℹ️
For advanced Nvidia optimizations use Nvidia Profile Inspector to disable options like Vertical Sync, Power Management in Prefer Maximum Performance mode, and aggressive Texture Filtering.

AMD - Performance Optimizations

Medium

Configure AMD GPU for optimal gaming performance

💡 Improved GPU performance and reduced power state transitions

Disable ULPS (Ultra Low Power State)

ULPS causes power state transitions that can create stuttering. Disabling improves frame consistency.
PowerShell / CMD
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000" New-ItemProperty -Path $path -Name "EnableUlps" -PropertyType DWord -Value 0 -Force

Enable Anti-Lag and Boost

Enables AMD Anti-Lag and performance boost features
PowerShell / CMD
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000\UMD" New-Item -Path $path -Force | Out-Null New-ItemProperty -Path $path -Name "Main3D_DEF" -PropertyType String -Value "1" -Force New-ItemProperty -Path $path -Name "Main3D" -PropertyType String -Value "1" -Force

Disable MPO (Multi-Plane Overlay)

Medium

Disable Multi-Plane Overlay to prevent stuttering issues

💡 Improved frame rate stability and reduced stuttering

Disable MPO System-Wide

MPO can cause stuttering in some games. Disabling improves framerate consistency.
PowerShell / CMD
New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\Dwm" -Name "OverlayTestMode" -PropertyType DWord -Value 5 -Force

Disable Fullscreen Optimizations

Medium

Disable Windows fullscreen optimizations for better performance

💡 Better frame consistency and reduced input lag in fullscreen games

Disable System-Wide

Disables fullscreen optimizations globally for all games
PowerShell / CMD
New-ItemProperty -Path "HKCU:\System\GameConfigStore" -Name "GameDVR_DXGIHonorFSEWindowsCompatible" -PropertyType DWord -Value 1 -Force New-ItemProperty -Path "HKCU:\System\GameConfigStore" -Name "GameDVR_FSEBehavior" -PropertyType DWord -Value 2 -Force

Per-Game Configuration

ℹ️
You can also disable fullscreen optimizations per-game: Right-click .exe → Properties → Compatibility → Check 'Disable fullscreen optimizations'

GPU Driver Cleanup

Medium

Clean old GPU drivers before applying advanced optimizations

💡 Prevents driver conflicts and ensures clean driver installation

Clean GPU Drivers Safely

⚠️
Before applying advanced optimizations, clean old drivers using DDU (Display Driver Uninstaller) in Safe Mode to prevent conflicts.

Instructions

ℹ️
1. Boot into Safe Mode 2. Download and run DDU (Display Driver Uninstaller) 3. Select your GPU and click Clean and Restart 4. Install latest drivers from Nvidia or AMD
