Windows Optimization for Gaming
A clean Windows configuration won't magically double your FPS, but it removes background contention that causes stutter and inconsistent frame times. Everything below is reversible and uses built-in Windows features — no third-party 'optimizers', no registry edits, and nothing that disables security updates.
Enable the gaming-focused power settings
Windows throttles the CPU to save power by default. For desktops and plugged-in laptops, letting the CPU reach its full clocks improves 1% lows and reduces micro-stutter.
- 1Open Settings → System → Power & battery and set the power mode to 'Best performance' (or 'Balanced' on a laptop you also use unplugged).
- 2On laptops, keep the charger connected while gaming — battery power caps the CPU and GPU aggressively.
- 3Enable 'Hardware-accelerated GPU scheduling' in Settings → System → Display → Graphics → Change default graphics settings.
Turn on Game Mode and per-app GPU preference
Game Mode tells Windows to prioritise the foreground game and defer background tasks like Windows Update installs while you play.
On laptops with two GPUs, make sure each game is assigned to the discrete GPU rather than the integrated one.
- 1Settings → Gaming → Game Mode → On.
- 2Settings → System → Display → Graphics → select your game → Options → 'High performance'.
Reduce background contention
The biggest real-world FPS killer is other software competing for CPU, RAM and disk. You don't need a 'debloater' — just close what you aren't using.
- 1Open Task Manager → Startup apps and disable launchers/updaters you don't need at boot.
- 2Quit browser tabs, streaming overlays and chat apps before competitive sessions.
- 3Keep at least 15% of your SSD free so the OS and shader caches have room to work.
Keep drivers and Windows current
Up-to-date GPU drivers frequently ship game-specific performance fixes. Windows updates include scheduler and DirectX improvements. Update both — but if a specific driver regresses performance in a game you play, it's fine to roll back to the previous stable release.
Key Takeaways
- Use 'Best performance' power mode on desktops and plugged-in laptops.
- Enable Game Mode and assign games to your discrete GPU.
- Close background apps instead of installing risky 'optimizer' tools.
- Keep GPU drivers current; roll back only if a release hurts your games.
