How to Improve Your Gaming PC's Performance Without Upgrading Hardware

Not ready to spend $800+ on a new GPU? You'd be surprised how much performance is sitting untapped in your current gaming PC. These optimisation steps cost nothing and can deliver meaningful FPS gains.

1. Update Your GPU Drivers

NVIDIA and AMD release driver updates specifically optimised for new game releases. Running outdated drivers can cost you 10–20% performance on recent titles. Download the latest drivers directly from NVIDIA's or AMD's websites — not from Windows Update.

2. Enable Game Mode in Windows 11

Windows Game Mode prioritises CPU and GPU resources for your active game, reducing background process interference. Go to Settings → Gaming → Game Mode and toggle it on. It's free performance with a single click.

3. Set Your Power Plan to High Performance

Windows defaults to Balanced power plans, which throttle CPU performance to save energy. Switch to High Performance (or Ultimate Performance on Windows 11 Pro) for consistent maximum clock speeds during gaming sessions.

4. Clean Your PC's Interior

Dust accumulation causes thermal throttling — your CPU and GPU automatically reduce their clock speeds when running too hot. A $10 can of compressed air from any Australian hardware store can recover 5–15% performance if your PC hasn't been cleaned in over a year.

5. Check for Background Applications

Streaming apps, browser tabs, Discord video calls, and Windows Update processes all compete for RAM and CPU. Close unnecessary applications before launching demanding games and check Task Manager for unexpected background processes.

6. Enable XMP/EXPO in BIOS

Most gaming PCs ship with RAM running at its baseline speed, not the rated speed on the box. Enable XMP (Intel) or EXPO (AMD) in your BIOS settings to unlock the rated RAM frequency — this can improve gaming performance by 5–10% depending on the game.
