Hello, I see you're experiencing high CPU usage while playing PUBG. You mentioned a recent period of inactivity since January when everything ran smoothly, but now your system stays busy at 94-100% CPU while GPU usage is only 20-50%. This causes stuttering and significant drops in FPS. Sometimes it hits 100% then suddenly falls to 40-60fps, especially during intense moments like fighting enemies or looting. Your current specs are:
- CPU: i5-4460
- GPU: Zotac GTX 1070
- Motherboard: MSI B85 G43
- RAM: Team Dark 4x4GB DDR3
- PSU: Corsair CX600M
- OS: Windows 10 Pro
You noted that CPU usage spikes only when playing PUBG, not other demanding games like Monster Hunter World or Assassin Creed Odyssey. Your hardware is quite old—7 years in, yet temperatures stay normal during gameplay (CPU <55%, GPU <60%). You’ve tried cleaning Windows, following a performance guide, and disabling background apps except MSI Afterburner, Rivaturner, Lightshot, Steam, and Discord. You also turned off Discord hardware acceleration and overlays, and Steam.
If you're open to suggestions, here are a few things you could try:
- Check for background processes using Task Manager or Resource Monitor.
- Ensure no unnecessary software is running in the background.
- Consider updating drivers, especially for your GPU and motherboard.
- If possible, run a CPU stress test to confirm if it's truly bottlenecked.
- If you're comfortable, consider a more modern CPU upgrade later.
Let me know what you find, and I can help further!
Have you adjusted the game to 60 frames per second? Are you using a monitor with a very high refresh rate? You might also find in-game options that can be lowered to ease the strain.
The issue appears uniform across the game. CPU usage remains steady during gameplay. Temperatures were recorded while playing.
It's consistent whenever I connect into any maps, regardless of when I cap it or not. The background usage stays at 78% or higher in any game. I'm tracking it with MSI Afterburner and Rivaturner, but both show normal idle CPU at 37 and GPU at 35, all running below 60 while playing games.
