Overview: GamePP troubleshoots persistent stuttering after game optimization. Using CPU Intel Core i9 14900K in game Apex Legends, after hitting game optimization CPU spikes still over 90%, frame time all over, worse on high refresh screens.
TroubleshootingGamePP Performance Stats show residual background processes post-optimization causing CPU spikes, exacerbating VRAM bottleneck and 25ms frame time variance. 1. Launch GamePP, go to 'Game Optimization' module; 2. In 'Game Settings Optimization' tab, confirm checks for 'Close system background processes' and 'Release memory'; 3. Click 'Start Optimization' to re-execute; 4. Switch to 'Hardware Monitoring' → 'Desktop Monitoring', add CPU usage and temp curves; 5. If spikes persist, go to 'Hotkey Shielding' tab, check 'Shield Win' and 'Lock English input method'; 6. Back to 'Game Settings Optimization', check 'Switch Windows power plan to high performance'; 7. Combine with 'Performance Stats' tab to review historical FPS curves for effect; 8. High refresh verify: Limit frame rate to monitor refresh; 9. If ineffective, check 'Runtime Library Repair' tab to scan DirectX; 10. Save and restart GamePP, test multiple rounds in Apex; 11. Note: One-time effect, re-optimize after game exit; 12. Cross-verify: Record 10-min data in 'Lab' tab for comparison. Pre- and post-optimization comparison: 1% Low FPS up 20%, temperature down 6°C. From official guide and player tests.
