You can often improve game smoothness without replacing hardware by first identifying whether the problem is low frame rate, stutter, input delay, or slow loading. Then change one relevant setting at a time and compare the same scene. Results depend on your Windows version, GPU, game, and current bottleneck; no setting guarantees a particular FPS gain.

Identify what is actually slowing the game

Different symptoms point to different causes. Note the game, resolution, graphics settings, whether the PC is a laptop or desktop, and when the problem occurs before changing anything.

  • Low FPS throughout play: The PC may be struggling to render the game at its current resolution or settings.
  • Dips in busy scenes: A particular effect, crowded scene, or background task may be contributing.
  • Stutter or hitching: Look for intermittent resource pressure or a setting that changes performance from moment to moment.
  • Input delay: The delay may relate to local rendering or presentation, rather than the game’s average frame rate.
  • Slow loading: Loading time is distinct from in-game FPS and may be affected by storage or other system constraints.

Online lag is different from local rendering performance: a network connection can make multiplayer actions feel delayed even when the PC renders frames smoothly. Microsoft lists limited storage, too many startup apps, outdated software, and hardware that no longer meets current requirements among possible reasons Windows runs slowly. See Microsoft’s Windows performance tips.

Reduce background work and keep software current

Close applications you do not need while gaming, especially if they are consuming system resources. Review startup apps and disable ones you do not need to launch with Windows. Check for Windows updates and graphics-driver updates through Windows Update or the PC or GPU manufacturer’s supported channel.

These steps can remove avoidable competition or address outdated software, but they cannot overcome every hardware limit. You do not need a third-party “optimizer” utility to try the settings in this guide.

Make sure the game uses the intended GPU

This check applies to a Windows 11 PC with more than one graphics processor, such as integrated graphics alongside a discrete GPU. If a game is assigned to the less capable processor, set its Windows preference to High performance:

  1. Open Settings > System > Display > Graphics.
  2. Select the game. If it is not listed, add it using the available browse option.
  3. Open Options, choose High performance if that corresponds to the GPU you want the game to use, and save the choice.
  4. Restart the game so it uses the changed preference.

The preference is relevant only when multiple GPUs are available; it is not a universal FPS setting. Microsoft documents the GPU preference and graphics controls in its Windows 11 windowed-game settings guidance.

Try Windows 11 windowed-game optimization when it fits

Microsoft says, “Optimizations for windowed games improves gaming performance for DirectX 10 and DirectX 11 games running in windowed and borderless windowed modes.” The feature is limited to compatible DirectX 10 and DirectX 11 games in those display modes; it is not a general-purpose setting for every game or a promise of higher FPS.

For compatible games, the option transitions the presentation path from the legacy blt model to flip model. Microsoft describes this as reducing frame latency and enabling supported features such as Auto HDR and variable refresh rate (VRR). Find the per-app control under Settings > System > Display > Graphics. If a game behaves worse after enabling it, test turning it off for that game and compare the same scene.

Lower costly in-game settings in small steps

Use the game’s own graphics menu to test changes to resolution or render scale, ray tracing, shadows, anti-aliasing, and other demanding effects. The impact depends on the game and the component limiting performance, so there is no reliable universal order or FPS gain to promise.

AMD’s Radeon Boost is a vendor-specific option that changes resolution in supported games based on user input, which may improve performance at the cost of image detail while the resolution changes. Its availability and options vary by system. Do not assume it works with every game or GPU; check AMD’s Adrenalin graphics-settings documentation.

NVIDIA: test maximum-performance power management selectively

NVIDIA describes Prefer maximum performance as a possible remedy in certain applications when incorrect clock throttling is causing low FPS. Test it for the affected game rather than applying it everywhere. Higher power use or heat may not be worthwhile if performance does not visibly improve. NVIDIA’s steps and qualification are in its Power management mode guidance.

AMD: distinguish performance features from power-saving controls

AMD Software: Adrenalin Edition includes graphics options and per-game profiles, but available settings vary by configuration. Radeon Boost changes resolution in supported games; Radeon Chill regulates frame rate to conserve power and reduce heat, so it is not a general FPS-maximizing switch. Check AMD’s Adrenalin graphics-settings documentation for feature availability and controls.

Intel: verify Application Optimization eligibility

Intel Application Optimization changes thread scheduling for selected software titles and may improve performance, but it is not a universal game setting. It requires supported processors and platform conditions, and results vary with configuration and graphics capability. Check Intel’s current supported-title list and requirements before trying it in the Intel Application Optimization overview.

Know when settings have reached their limit

Settings changes can correct a misconfiguration or reduce avoidable overhead, but they cannot make every underpowered CPU or GPU meet a demanding game’s requirements. If the game remains limited with low settings and repeated tests show the same result, configuration changes may have reached their ceiling. The official feature descriptions above do not establish a fixed FPS gain across different PCs, games, and settings, so judge changes on your own system rather than expecting a universal number.
