🎮 Gaming FPS Mode

Intune Platform Script · Boosts FPS by tuning power, killing background junk, and watching for Steam

Runs as the logged-on user — all registry writes target HKCU. The Steam watcher scheduled task runs at logon with elevated rights. Don't push this to shared kiosks or conference room devices.

What this does: sets High Performance power plan · enables Windows Game Mode · disables Xbox DVR recording overhead · kills SysMain (Superfetch) · creates a logon task that suspends OneDrive and boosts Steam process priority whenever Steam is detected running.

Script

Set High Performance power plan power

Switches the active power plan to High Performance. Single biggest FPS improvement on laptops.

# Set High Performance power plan
powercfg /setactive 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c

Enable Windows Game Mode registry

Tells Windows to prioritize the foreground game for CPU and GPU resources automatically.

# Enable Windows Game Mode via registry
New-Item -Path "HKCU:\Software\Microsoft\GameBar" -Force | Out-Null
Set-ItemProperty -Path "HKCU:\Software\Microsoft\GameBar" -Name "AllowAutoGameMode" -Value 1 -Type DWord -Force
Set-ItemProperty -Path "HKCU:\Software\Microsoft\GameBar" -Name "AutoGameModeEnabled" -Value 1 -Type DWord -Force

Disable Xbox Game DVR recording registry

Game Bar's background recording eats GPU encode budget even when you're not using it.

# Disable Xbox Game Bar background recording
New-Item -Path "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR" -Force | Out-Null
Set-ItemProperty -Path "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR" -Name "AppCaptureEnabled" -Value 0 -Type DWord -Force
New-Item -Path "HKCU:\System\GameConfigStore" -Force | Out-Null
Set-ItemProperty -Path "HKCU:\System\GameConfigStore" -Name "GameDVR_Enabled" -Value 0 -Type DWord -Force

Disable SysMain (Superfetch) service

SysMain pre-loads apps into RAM. On gaming rigs with fast SSDs it just wastes memory that games need.

# Stop and disable SysMain (Superfetch)
Stop-Service -Name SysMain -Force -ErrorAction SilentlyContinue
Set-Service -Name SysMain -StartupType Disabled

Steam watcher — suspend OneDrive + boost priority scheduled task

Creates a logon task that polls every 30s. When Steam is running: kills OneDrive sync and raises Steam to High CPU priority. Keeps running silently in the background.

# Create logon task: kill OneDrive and boost Steam when gaming
$cmd = 'while($true){ if(Get-Process steam -EA 0){ Stop-Process -Name OneDrive -Force -EA 0; Get-Process steam -EA 0 | ForEach-Object { $_.PriorityClass = "High" } }; Start-Sleep 30 }'
$action  = New-ScheduledTaskAction -Execute "powershell.exe" -Argument "-WindowStyle Hidden -NonInteractive -Command `"$cmd`""
$trigger = New-ScheduledTaskTrigger -AtLogOn
$settings = New-ScheduledTaskSettingsSet -ExecutionTimeLimit 0 -AllowStartIfOnBatteries -DontStopIfGoingOnBatteries
Register-ScheduledTask -TaskName "SteamFPSWatcher" -Action $action -Trigger $trigger -Settings $settings -RunLevel Highest -Force
