Windows 11 has matured significantly since launch, and with the right optimisation tweaks, you can unlock meaningful performance gains for gaming without sacrificing system stability or features. These tested adjustments can collectively deliver 10 to 15 or more additional frames per second in demanding titles, with the exact improvement depending on your hardware configuration and the games you play.
The single most impactful change is ensuring your GPU drivers are current. NVIDIA and AMD both release game-ready drivers that include optimisations for new titles and performance fixes for existing ones. Use GeForce Experience or AMD Adrenalin to stay updated, but avoid beta drivers unless you specifically need a fix they include. Clean driver installations using Display Driver Uninstaller can resolve persistent performance issues caused by corrupted driver files from previous updates.
Game Mode in Windows 11 should be enabled, which it is by default. This feature prioritises system resources for the active game and prevents Windows Update from installing updates or restarting during gameplay. Navigate to Settings, Gaming, Game Mode to verify it is active. While you are in the Gaming settings, also enable Hardware-accelerated GPU scheduling if your hardware supports it. This feature allows the GPU to manage its own video memory scheduling, reducing latency and improving frame pacing in many titles.
Power settings have a significant impact on performance. Set your power plan to High Performance or Ultimate Performance rather than the default Balanced plan. The Balanced plan dynamically adjusts CPU clock speeds to save power, which can introduce micro-stutters and reduce sustained performance in games. To access Ultimate Performance, you may need to enable it through a PowerShell command if it does not appear in your power plan options by default.
Background processes are a common source of performance loss. Disable unnecessary startup programs through Task Manager, and consider setting your game to High priority in Task Manager while playing. Disable overlays you do not actively use, including those from Discord, Steam, and NVIDIA, as each overlay consumes a small amount of GPU resources.
Visual effects within Windows itself can be trimmed. Navigate to System Properties, Advanced, Performance Settings, and select Adjust for best performance, then re-enable only the visual effects you personally value, such as smooth font edges. This frees up a small amount of system resources that can benefit gaming performance, particularly on systems with limited RAM.
For NVIDIA users, the NVIDIA Control Panel offers several game-changing settings. Set Power management mode to Prefer maximum performance, Texture filtering quality to High performance, and ensure Low Latency Mode is set to On or Ultra depending on whether you prioritise input responsiveness. AMD users should explore the Radeon Anti-Lag and Radeon Boost features in Adrenalin for similar latency and performance benefits.
