How to boost your gaming PC performance in 2026

Before buying a new PC, several tweaks can unlock 10 to 30% more FPS at zero cost. In 2026, a well-configured mid-range PC often outperforms a newer machine left on default settings. Here are the 8 most effective actions, ranked by impact.

1) Update your GPU drivers (immediate impact)

NVIDIA Game Ready drivers and AMD Adrenalin releases are optimized for each major game launch. An outdated driver from 6 months ago can cost 5–15% FPS on recent titles.

For NVIDIA: open GeForce Experience or download directly from nvidia.com. For AMD: use AMD Software Adrenalin Edition. Always restart after installation for changes to take effect.

2) Enable XMP or EXPO for your RAM

Most DDR4 and DDR5 kits ship at 2133 or 3200 MHz by default, even if they are certified for 3600, 4800, or 6000 MHz. Enabling XMP (Intel) or EXPO (AMD) in BIOS takes 2 minutes and can add 5–20% FPS in CPU-intensive games like CS2, Valorant, or Cyberpunk 2077.

Access BIOS on startup (DEL or F2), find the 'XMP' or 'EXPO' setting under memory options, and enable the highest compatible profile for your motherboard.

3) Optimize Windows 11 for gaming

Disable unnecessary startup apps (Task Manager > Startup), set Power Plan to High Performance, and disable transparency and animations to reduce CPU overhead.

Go to Settings > System > Display > Graphics and set individual games to use the high-performance GPU. This single step reduces input latency and improves frame consistency.

4) Enable Game Mode and HAGS

Game Mode (Settings > Gaming > Game Mode) prioritizes CPU/GPU resources toward active games and reduces Windows interruptions. HAGS — Hardware-Accelerated GPU Scheduling (Settings > Display > Graphics > Default graphics settings) delegates GPU memory management to hardware, reducing micro-stutters.

Both are supported on NVIDIA (RTX 20/30/40) and AMD (RX 5000+). If you use an older GPU, test HAGS and disable it if you experience instability.

5) Fine-tune in-game graphics settings

Render resolution is the single most powerful lever: dropping from 100% to 85% can gain 15–25% FPS with minimal visual impact. In Cyberpunk 2077, Fortnite, or Apex Legends, this setting is called 'render scale' or 'dynamic resolution'.

Prioritize lowering: shadows (Ultra → High), real-time reflections (disable if FPS is too low), and ambient occlusion. Draw distance and high-res textures barely affect FPS but consume VRAM.

6) Clean and check thermals

An overheating PC automatically throttles performance. Clean fans and heatsinks with compressed air every 6 months. Monitor temps with HWiNFO64: GPU < 83°C and CPU < 90°C under load are healthy targets.

If temperatures exceed these thresholds, replace the CPU thermal paste — a 15-minute task that can drop temps by 10–20°C and recover throttled performance.

7) Disable overlays and background recording

Discord, GeForce Experience, Xbox Game Bar, and Steam all run overlays that consume CPU and RAM in the background. Disable Xbox Game Bar background recording (Settings > Gaming > Captures) and any overlays you are not actively using.

On entry-level PCs or with only 8 GB RAM, these savings alone can provide 5–10% extra FPS.

8) When optimization is not enough: time for an upgrade

If after all these tweaks your GPU is still running at 99% and FPS remain insufficient for your target games, software cannot help further. This signals a genuine hardware bottleneck.

To identify whether GPU or CPU is limiting you, monitor both with HWiNFO while playing: if GPU is at 99% and CPU at 60%, GPU is the bottleneck. If it is the reverse, a newer CPU or more RAM may help before replacing the graphics card.
