🗜️ Disable RAM Compression

Medium Impact

Disables automatic memory compression that Windows performs.

💡 Reduces memory access latency

Disable Memory Compression

PowerShell / CMD
Disable-MMAgent -MemoryCompression

🔓 Disable Meltdown/Spectre

High Impact

Improves performance by disabling security mitigations (gaming only).

💡 Increases CPU performance

Kernel-Managed Memory

PowerShell / CMD
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" New-ItemProperty -Path $path -Name "FeatureSettings" -PropertyType DWord -Value 1 -Force New-ItemProperty -Path $path -Name "FeatureSettingsOverride" -PropertyType DWord -Value 3 -Force New-ItemProperty -Path $path -Name "FeatureSettingsOverrideMask" -PropertyType DWord -Value 3 -Force

⚠️ Security Warning

⚠️
⚠️ IMPORTANT: Disabling Meltdown/Spectre significantly reduces your system's security. Only apply on PCs dedicated exclusively to gaming.

💾 DisablePagingExecutive

Medium Impact

Prevents drivers from being paged to virtual memory, keeping them in RAM.

💡 Improves driver stability and performance

Keep drivers in RAM

PowerShell / CMD
New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" -Name "DisablePagingExecutive" -PropertyType DWord -Value 1 -Force

📊 LargeSystemCache

Medium Impact

Configures system cache size to optimize performance.

💡 Optimizes cache based on usage (gaming or LAN)

Possible values

0: ~8 MB cache (recommended for gaming) 1: Up to RAM-4MB (for LAN transfers)

Configure for gaming

PowerShell / CMD
New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" -Name "LargeSystemCache" -PropertyType DWord -Value 0 -Force

📝 Note

📝
Value 1 improves LAN transfers but may have issues with ATI/AMD drivers. For gaming, use 0.

📄 Configure Page File

High Impact

A large page file (32GB) improves microstuttering in games.

💡 Reduces microstuttering and improves fluidity

Configure 32GB page file

PowerShell / CMD
wmic computersystem where name="%computername%" set AutomaticManagedPagefile=False wmic pagefileset where name="C:\\pagefile.sys" set InitialSize=32768,MaximumSize=32768

⚠️ Warning

⚠️
⚠️ WARNING: System may become unstable if you don't have enough RAM. Restart Windows after applying this change.

🔐 NTFS/ReFS Protection

Low Impact

Disables additional filesystem protection mitigations.

💡 Increases I/O performance

Disable additional mitigations

PowerShell / CMD
New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager" -Name "ProtectionMode" -PropertyType DWord -Value 0 -Force

⏱️ Realtime Priority for csrss.exe

High Impact

Sets maximum priority for the csrss.exe process (session manager).

💡 Improves system responsiveness to critical events

Configure maximum priority

PowerShell / CMD
$path = "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\csrss.exe\PerfOptions" New-Item -Path $path -Force | Out-Null New-ItemProperty -Path $path -Name "CpuPriorityClass" -PropertyType DWord -Value 4 -Force New-ItemProperty -Path $path -Name "IoPriority" -PropertyType DWord -Value 3 -Force

💡 Summary

Low Impact

Important: these optimizations improve gaming performance but reduce security and stability.

💡 Understanding the risks

⚠️ Important

⚠️
These optimizations improve gaming performance but reduce system security and overall stability. Only apply on PCs dedicated exclusively to gaming and controlled environments.
