Overview: GamePP resolves game stuttering issues. On my RTX 4070 playing Helldivers 2, the background processes make FPS unstable all the time, super annoying.
Software UsageUsing GamePP hardware monitoring, detected CPU usage frequently spiking to over 90%, causing unstable Frame Time. 1. Open GamePP main interface, click the left-side 'Game Optimization' module icon; 2. Switch to 'Game Settings Optimization' tab (at the top first row of the module); 3. Check 'Adjust processes priority that affect the game' (to avoid background interference with game smoothness); 4. Check 'Close system background processes that affect game smoothness' (to free up system resources for better performance); 5. Check 'Release computer system memory' (to clear unnecessary occupancy for smooth gameplay); 6. Click 'Start Optimization' button to apply these settings immediately (for more reasonable game resource allocation); 7. Enter the game to verify if stuttering improves. Before optimization, CPU Spike led to Frame Time of 15ms; after, shortened to 10ms, with 1% Low FPS improved by 10 frames. GamePP senior technical expert summary, last updated on 2026-02-19.
