Optimizing Windows for Gaming – How Do System Settings Affect FPS?

Do you already have a powerful graphics card and a processor with plenty of headroom, yet the game still won't run at more than a few dozen frames per second? Before you start looking for the problem in your hardware, check your operating system. Windows 10 and Windows 11 have built-in mechanisms that, when set to default, can significantly limit performance.

Windows 10/11 as a gaming platform – what improvements has Microsoft made for gamers?

Windows 10 introduced Game Mode and the first implementations of HAGS (Hardware-Accelerated GPU Scheduling), while Windows 11 took things a step further—adding support for DirectStorage and Auto HDR, and improving task scheduling algorithms for multi-core processors. On new hardware, Windows 11 delivers slightly better performance, but on older machines, its higher requirements can have the opposite effect. More important than the version of the system is how it is configured.

Game Mode – Myth or a Real Help in Stabilizing Frame Rates?

Game Mode redirects CPU and RAM resources to the running game, limiting the activity of background processes. On systems with limited resources—8 GB of RAM, a quad-core processor—it can effectively stabilize the frame rate and reduce fluctuations. On high-end systems, the difference is often imperceptible, and in some configurations, this feature may even cause microscopic delays. In short: Game Mode does not work the same on low-end and high-end hardware. It’s worth testing it in practice. For this reason, you should enable benchmark mode. 

GPU hardware-accelerated scheduling – a hidden feature worth knowing about

HAGS allows the graphics card to manage its own VRAM independently, rather than passing that responsibility to the CPU. This feature requires a compatible driver and a GPU that supports this standard—NVIDIA cards from the GTX 10 series onward or AMD cards based on the RDNA architecture. You can enable it in “Settings” → "System” → "Display” → "Graphics” → “Default graphics settings." After enabling this, restart your computer.

Let's turn off distractions—notifications, Focus Assist, and background updates

Notifications, OneDrive syncing, and background updates—each of these processes consumes system resources while you’re gaming. Focus Assist (in Windows 11: “Do Not Disturb”) can be configured to turn on automatically when you launch a full-screen app: “Settings” → “System” → “Focus Assistant” → “"Automatic mode." It’s a good idea to postpone Windows updates and schedule them for nighttime—in Pro versions, you’ll find this option under Settings → Windows Update → Advanced options. Among the system services, you can safely disable, among others, Tablet PC Input Service, Print Spooler, and Remote Registry. 

Power supply ""High Performance" – why default settings are throttling your hardware

The default power plan reduces the CPU clock speed when the system determines that full power isn't needed. In games, the CPU has to rapidly increase its clock speed multiple times per second, and any delay in this response directly translates to input lag and frame rate fluctuations. Switching the plan to “High Performance” eliminates this problem. On laptops, it’s best to use this mode only when plugged in. In Windows 11, the plan is sometimes hidden—you can unlock it via “Control Panel” → “Power Options” → “Show additional plans.”

DirectStorage and Auto HDR – technologies that make Windows 11 worth having

DirectStorage allows the graphics card to retrieve data directly from an NVMe drive, bypassing the CPU, which reduces level load times. Auto HDR automatically expands the color palette in games not natively designed for this standard—older titles thus gain color depth they originally lacked. Both technologies are unavailable in Windows 10, which is a key difference between the two versions of the operating system. If your computer meets the requirements for Windows 11 and you have an NVMe drive, upgrading to the new version makes real sense in the context of gaming.

A Clean System Means More FPS – How Bloatware Affects Gaming Performance

On brand-new laptops, manufacturers often install dozens of apps that launch along with the operating system. Each one takes up RAM and puts a strain on the processor, without offering anything in return. On older machines, the effects of removing them can be surprising—a dozen or so extra FPS just because the processor no longer has to handle unnecessary processes. Check what starts up with the system in Task Manager (Ctrl + Shift + Esc) → the “Startup” tab, and uninstall unnecessary applications via “Settings” → “Apps” → "Installed apps."

Why a legal system is essential for a player

Pirated Windows poses a real threat to gamers. The cracks used to activate illegal copies of the operating system very often contain viruses that steal login credentials—for Steam, Epic Games, web browsers, or bank accounts. An unactivated system also has limited access to updates, which means new features like DirectStorage or Auto HDR may simply not work.
