Nothing ruins a clutch moment in online multiplayer or an immersive single-player session faster than sudden FPS drops, screen tearing, and input lag. Even if you have a capable graphics card, poor Windows configuration, hidden background bloatware, or incorrect in-game settings can severely hold back your system’s performance.
In this ultimate performance guide, we walk you through the most effective, tested, and safe ways to boost FPS and reduce lag on any gaming PC or laptop.
1. Enable Windows Game Mode & HAGS :
Modern versions of Windows come equipped with built-in features specifically designed to optimize your system hardware for gaming.
Enable Game Mode: Go to Settings > Gaming > Game Mode and toggle it ON. Game Mode prioritizes system CPU threads for your active game while preventing background Windows updates during gameplay.
Turn On Hardware-Accelerated GPU Scheduling (HAGS): Go to Settings > System > Display > Graphics > Change default graphics settings, and enable Hardware-Accelerated GPU Scheduling. This lets your graphics card manage its own VRAM memory directly, reducing latency and stuttering.
2. Optimize High-Impact In-Game Settings :
Setting every graphic option to “Ultra” looks great, but several visual settings drastically reduce your frame rate for very minor visual gains. Lowering just these specific heavy settings can yield a 20% to 40% boost in FPS:
Shadow Quality: Change from Ultra/High to Medium. Shadows place immense strain on both CPU and GPU.
Volumetric Fog & Lighting: Lower these to Low or Medium. They consume substantial video RAM without adding much to fast-paced gameplay.
Ray Tracing: Turn OFF unless you have a high-end RTX GPU. Ray tracing causes massive frame rate drops.
Motion Blur & Depth of Field: Turn these OFF. Disabling them improves visual clarity and slightly reduces rendering load.
3. Leverage AI Upscaling (DLSS, FSR, XeSS) :
If your graphics card supports AI upscaling technology, utilizing it is the single biggest “free” performance upgrade available.
Nvidia DLSS / AMD FSR / Intel XeSS: These tools render the game internally at a slightly lower resolution and use AI algorithms to reconstruct the image to native quality.
Pro Tip: Set upscaling mode to Quality or Balanced to gain 30–50+ extra FPS while maintaining a sharp picture.
4. Keep Graphics Drivers Updated & Optimized :
Outdated GPU drivers are one of the most common causes of low performance in newly released games.
Nvidia Users: Open GeForce Experience / Nvidia App, check the Drivers tab, and install the latest Game Ready Driver.
AMD Users: Open AMD Software: Adrenalin Edition and check for updates.
Nvidia Control Panel Tweaks: Right-click your desktop, open Nvidia Control Panel > Manage 3D Settings, set Power Management Mode to Prefer Maximum Performance, and set Low Latency Mode to Ultra or On.
5. Clean Up Background Bloatware & Startup Apps :
Unnecessary applications running in the background steal valuable CPU cores and system RAM:
Press Ctrl + Shift + Esc to open Task Manager.
Click on the Startup Apps tab.
Disable non-essential apps (like launchers, browser helpers, or cloud sync tools) from starting automatically when you turn on your PC.
Close web browsers (like Chrome or Edge) with multiple open tabs before launching demanding games.
6. Monitor System Thermals & Prevent Throttling :
When your CPU or GPU reaches high temperatures (usually above 85°C–90°C), the hardware automatically slows itself down to avoid hardware damage. This process is called thermal throttling and causes severe frame drops.
Ensure your PC cabinet has proper airflow and clean out dust buildup using compressed air.
For gaming laptops, use a dedicated laptop cooling pad during extended gaming sessions.
Consider replacing thermal paste if your PC is more than 2 years old and running hot.
