Summary: How GamePP combines hotkey shielding and optimization to solve input switching induced lag in games. In game Valorant, my processor Intel Core i9 14900K gets CPU Spike from Shift+Space input switch, causing frame time spikes and drops during figh
Software UsageUsing GamePP Hardware Monitoring module, detect CPU Spike related to input method switching, combined with OSD monitoring to observe Frame Time anomalies. 1. Open GamePP main interface, click the left-side "Game Optimization" module icon; 2. Switch to "Hotkey Shielding" tab (located at the top second row of the module); 3. Check "Shield 'Shift+Space'" option, to prevent input method mis-trigger causing delay; 4. Check "Lock English input method in game" option, to ensure stable input in game avoiding stutters; 5. Switch back to "Game Settings Optimization" tab, check "Close system background processes that affect game smoothness" to further reduce load; 6. Check "Adjust processes priority that affect the game" option, to improve game response speed; 7. Click "Start Optimization" button, to execute all settings for immediate effect; 8. Go to "Hardware Monitoring" module's "In-Game Monitoring" tab, enable GamePP OSD Overlay to monitor Frame Time for cross-verification; 9. If still not ideal, adjust "Custom Hotkey" to set Ctrl+Shift+TAB for quick panel switch, real-time fine-tuning; 10. Save configuration and restart game, note setting refresh time to 2 seconds in high-resolution scenarios to avoid extra overhead. Before and after optimization, CPU Spike frequency reduced by 50%, frame generation time shortened by 8ms, Thermal Throttling risk lowered.
