Overview: GamePP advanced optimization for game hotkey interference, enhancing high-refresh-rate experience. In game Fortnite with CPU Intel Core i9 14900K, at 144Hz high refresh, accidentally hit Win key pops to desktop, CPU load unstable, 1% Low FPS dro
Software UsageGamePP monitoring shows frequent CPU Spike, with Thermal Throttling signs, hotkey misfires exacerbating uneven Frame Time, pinpointed as system hotkeys and background load overlap. 1. Launch GamePP, enter "Game Optimization" module; 2. Navigate to "Hotkey Shield" tab (module second row); 3. Check "Shield 'Win'" option, to prevent desktop popup; 4.
