The top 5 hidden PC settings you need to change right now to unlock your system’s hidden performance focus on maximizing your graphics card, reducing input lag, and unleashing your CPU’s true power. 1. Enable Hardware-Accelerated GPU Scheduling (HAGS)
Many brand-new or newly updated PCs have this crucial option turned off by default. Enabling it unloads intense graphical background tasks from your CPU and hands them directly to your GPU, which reduces latency and stabilizes your framerates. How to change it: Open Settings →right arrow System →right arrow Display →right arrow Graphics →right arrow Default graphics settings (or Advanced graphics settings).
The tweak: Toggle Hardware-accelerated GPU scheduling to On, then restart your PC. 2. Turn on Resizable BAR (Smart Access Memory)
This hidden BIOS-level setting allows your CPU to access your graphics card’s entire VRAM frame buffer at once, rather than in small, restricted chunks. Switching this on can net you an immediate performance boost in modern, asset-heavy video games.
How to change it: Restart your PC and repeatedly tap your motherboard’s BIOS key (usually Delete or F2).
The tweak: Navigate to the Advanced settings (often under PCI Subsystem Settings) and enable Re-Size BAR Support and Above 4G Decoding. 3. Change Your Windows Power Mode to “Best Performance”
