Background Processes and System Performance

Background processes and applications consume system resources (CPU, GPU memory, disk I/O) that could be allocated to CS2. Closing unnecessary background applications frees resources for gaming. Typical FPS loss from background processes: 10-30 FPS depending on the processes. Closing them can recover this performance.

Common culprits: streaming software (OBS, Streamlabs), browser with many tabs, file sync software (Google Drive, OneDrive), Discord, social media clients. Each of these consumes memory and CPU cycles. Close them before competitive matches. For casual play, the impact is less noticeable.

Use Task Manager (Ctrl+Shift+Esc) to identify CPU/memory-hungry processes. Look at CPU and Memory columns for processes consuming significant resources. If a process uses >5% CPU or >500MB memory and isn't necessary for gaming, consider closing it. Look for startup programs that run automatically and disable unnecessary ones.

Windows background tasks also consume resources. Disable Windows Update, indexing, and other background services before gaming for maximum FPS. However, this requires caution—disabling critical Windows services can cause instability. Focus on application-level closures (Discord, browser, etc.) which are safe and provide noticeable benefit.
