General Guide: Fixing CPU, GPU, or FPS Issues in PC Gaming (2025)

Can’t enjoy smooth gameplay due to stuttering, crashes, or low FPS? This guide will help you troubleshoot and optimize your PC gaming performance in 2025 across all titles.

Quick Fixes to Try First

  • Restart your PC to clear temporary issues.
  • Ensure Windows, your game, and drivers are fully updated.
  • Close unnecessary background applications via Task Manager.
  • Set Windows Power Plan to High Performance.
  • Verify game files using your launcher tools.
  • Lower demanding in-game settings like shadows and textures.
  • Monitor your CPU and GPU temperatures to avoid overheating.

1. Keep Your System and Software Updated

  • Update BIOS/UEFI via motherboard manufacturer's website.
  • Install the latest chipset drivers from AMD or Intel.
  • Update your GPU drivers using NVIDIA GeForce Experience, AMD Adrenalin, or Intel Arc Control.
  • Keep Windows fully updated through Settings > Windows Update.
  • Patch your games regularly via Steam, EA App, Epic Games Launcher, or others.

2. Perform a Clean GPU Driver Installation

  • Use Display Driver Uninstaller (DDU) in Safe Mode to completely remove old GPU drivers.
  • Reinstall the latest GPU drivers downloaded directly from NVIDIA, AMD, or Intel.

3. Optimize In-Game Graphics Settings

  • Lower GPU-intensive options such as shadows, textures, and anti-aliasing.
  • Disable V-Sync if you experience input lag or stutters.
  • Enable upscaling techniques if supported by your GPU:
    • DLSS (NVIDIA)
    • FSR (AMD)
    • XeSS (Intel)
  • Try different display modes (fullscreen, windowed, borderless) to find the best performance.
  • Disable overlays and telemetry features if they cause instability.
  • Experiment with launch options to force specific DirectX versions compatible with your setup.

4. Monitor Temperatures and Performance

  • Use software like HWMonitor, MSI Afterburner, or HWiNFO to track CPU and GPU temperatures.
  • Keep temperatures below ~80°C to avoid throttling.
  • Clean dust from system fans and heatsinks regularly.
  • Ensure your PC has proper airflow and cooling.
  • Reapply thermal paste if necessary (only if experienced).
  • Use overlays like Xbox Game Bar or MSI Afterburner to monitor FPS and system load in real time.

5. Manage Background Applications

  • Close unnecessary apps using Task Manager.
  • Disable startup programs to free system resources.
  • Enable Windows Game Mode under Settings > Gaming.
  • Disable hardware acceleration in applications such as Discord, Chrome, or Spotify.

6. Adjust Power Settings and BIOS Options

  • Set Windows Power Plan to High Performance (Settings > Power & Sleep > Additional Power Settings).
  • Enable RAM XMP/DOCP profile in BIOS to run at rated speeds.
  • Optionally disable CPU power-saving features like C-States in BIOS.
  • Enable Resizable BAR on supported platforms for GPU-CPU communication improvements.

7. Identify Hardware Bottlenecks

  • Use benchmarking tools like UserBenchmark, PassMark, CPU-Z, and GPU-Z.
  • Check for component mismatches, e.g. weak CPU bottlenecking a powerful GPU.
  • Aim for at least 16GB RAM; upgrade to 32GB for multitasking and demanding titles.

8. Verify Game Files and Storage Health

  • Verify and repair game files through your game launcher (Steam, EA, Epic, etc.).
  • Install games on an SSD rather than HDD for faster load times.
  • Check disk health with tools like CrystalDiskInfo.
  • Maintain at least 20% free disk space for optimal speed.

9. Scan for Malware and Unwanted Software

  • Perform full system scans with Windows Defender or third-party antivirus.
  • Use Malwarebytes to detect rootkits and hard-to-find malware.

10. Reinstall Game or Operating System (Last Resort)

  • Reinstall your game to fix missing or corrupted files.
  • Consider a clean Windows installation if issues persist across all applications.

Game-Specific Optimization Notes

  • Competitive FPS games (Valorant, CS:GO): Optimize for maximum FPS by lowering shadows, disabling post-processing, and enabling frame rate limits.
  • AAA Titles (Cyberpunk 2077, Battlefield 6): Use quality upscaling tech (DLSS, FSR, XeSS); balance visuals for smoother frame rates.
  • Open World Games (Elden Ring, Assassin’s Creed): Upgrade RAM and install on SSD to reduce texture pop-in and load times.
