7 Settings That Improve Performance on Any Gaming PC

Most gaming PCs leave performance on the table because of default settings that prioritize compatibility over speed. These seven tweaks cost nothing, take minutes to implement, and can meaningfully improve your frame rates and reduce stuttering.

1. Enable Game Mode and Hardware-Accelerated GPU Scheduling

Windows has two built-in features that most gamers never activate. Open Settings, then Gaming, and make sure Game Mode is turned on. This tells Windows to prioritize your game process and suppress background tasks like Windows Update during gameplay.

Next, go to Settings, System, Display, Graphics, and enable Hardware-Accelerated GPU Scheduling. This offloads some CPU-side scheduling work to your GPU, reducing input latency and smoothing frame delivery. It requires a relatively modern GPU (GTX 1000 series or newer, RX 5000 series or newer) and a restart to take effect.

2. Set Your Power Plan to High Performance

Windows defaults to "Balanced" power mode, which throttles CPU performance to save energy. For a desktop gaming PC, this is counterproductive. Open Control Panel, search for Power Options, and select "High Performance." On laptops, switch to this only when plugged in.

For AMD Ryzen processors, install the Ryzen High Performance power plan from the AMD chipset driver package. It optimizes thread scheduling specifically for Ryzen's architecture and can improve 1% lows significantly.

3. Update GPU Drivers and Use Optimal Settings

Outdated GPU drivers leave performance and stability improvements on the table. Both NVIDIA and AMD release game-ready drivers that can improve performance by 5-15% in specific titles. Use GeForce Experience or AMD Adrenalin to stay current.

In the NVIDIA Control Panel, set Power Management Mode to "Prefer Maximum Performance" and Texture Filtering Quality to "High Performance." For AMD, enable Radeon Anti-Lag and set Tessellation to "Override Application Settings" at 16x or lower. A quality DisplayPort cable ensures your GPU pushes full bandwidth to your monitor without bottlenecking.

4. Disable Startup Programs

Every program that launches at startup consumes RAM and CPU cycles. Open Task Manager with Ctrl+Shift+Esc, click the Startup tab, and disable everything you do not need running at boot. Common culprits include Discord, Spotify, OneDrive, Steam, Epic Games Launcher, RGB software, and manufacturer bloatware. Launch these manually when you need them.

This alone can free up 1-2 GB of RAM and reduce background CPU usage by 5-10%, directly translating to smoother gameplay especially on systems with 16GB or less of RAM.

5. Turn Off In-Game Settings That Tank Performance

Some graphics settings have an outsized impact on performance with minimal visual benefit. These are the first settings to lower or disable in any game:

Volumetric fog and clouds — Extremely GPU-intensive, often barely noticeable in gameplay. Motion blur — Most gamers disable this anyway. Turning it off saves GPU resources. Chromatic aberration and film grain — Pure post-processing effects that consume resources for an effect many players dislike. Shadow quality — Dropping from Ultra to High typically saves 10-15% GPU load with barely visible differences. Screen-space reflections at Ultra — Drop to Medium for a significant performance gain.

6. Install Your Games on an SSD

If any of your games are still on a traditional hard drive, move them to an SSD immediately. This does not improve FPS directly, but it drastically reduces loading times, eliminates texture pop-in during gameplay, and prevents hitching when the game streams assets from disk.

A Samsung 990 EVO 1TB NVMe SSD offers excellent sequential and random read speeds at a reasonable price. Even a budget SATA SSD is a massive upgrade over a hard drive.

7. Enable Resizable BAR / Smart Access Memory

Resizable BAR (NVIDIA) and Smart Access Memory (AMD) allow your CPU to access your GPU's entire VRAM pool simultaneously instead of in small chunks. This can improve performance by 5-10% in supported games with zero downsides.

Enable it in your BIOS under PCI settings (look for "Above 4G Decoding" and "Resizable BAR"), then verify it is active in GPU-Z or your GPU driver control panel. Most modern motherboards and GPUs support this feature, but it is often disabled by default.

These seven changes together can reclaim 15-30% of lost performance without spending a dime. Make them your first step before considering any hardware upgrades.
