If your games feel sluggish, stutter at the worst moments, or just don’t look as smooth as your hardware should allow, you’re not alone — and you usually don’t need new parts to fix it. This guide on How to Improve PC Gaming Performance is mostly about removing the things holding your system back: outdated drivers, wrong Windows settings, background apps eating resources, and in-game options set higher than your hardware can handle. Work through this guide in order, and most PCs gain a noticeable chunk of smoothness without spending a dirham.
Quick Answer
To improve PC gaming performance: update your GPU driver and Windows, turn on Game Mode and Hardware-Accelerated GPU Scheduling, set Windows power mode to Best Performance, close background apps, move games to an SSD, and lower the most expensive in-game settings first (shadows, ray tracing, volumetrics, and render resolution). Monitor your FPS before and after so you can measure what actually helped.
First, Find Out What’s Holding You Back
Before changing anything, spend five minutes finding your bottleneck — the one component maxed out while the others wait. Open Task Manager (Ctrl+Shift+Esc) while a demanding game runs and check CPU, GPU, and memory usage:
- GPU at 95–100%, CPU relaxed: You’re GPU-limited. Lower graphics settings or resolution — that’s the normal, healthy state for gaming.
- CPU at 95–100%, GPU well below 90%: You’re CPU-limited. Close background apps, lower CPU-heavy settings (draw distance, crowd density, physics), or consider that your processor is the weak link.
- RAM near 100%: 8 GB is the bare minimum today; 16 GB is the practical floor for modern games. High memory pressure causes stuttering, not just low FPS.
For a deeper method with proper monitoring tools, see our guide on how to check GPU bottlenecks. Knowing which part is the limit stops you from lowering settings that were never the problem.
Update Drivers and Windows (The Right Way)
Outdated graphics drivers are the number one silent performance killer — game-ready driver releases routinely include 5–15% improvements for new titles.
- GPU driver: Download it from the source, not Windows Update: NVIDIA’s driver download page or AMD’s support page. Choose “Custom install” and tick “Perform a clean installation” to wipe old settings that may conflict.
- Windows: Install all pending updates, then reboot. Some updates include scheduler and driver improvements that directly affect games.
- Chipset and BIOS: On AMD systems especially, the chipset driver from AMD’s site matters. A BIOS update can help on newer platforms, but only do it if you have a specific reason — a failed flash is worse than slightly old firmware.
Do the GPU driver first and retest before changing anything else. If a fresh driver somehow makes things worse, roll it back from Device Manager — bad releases happen.
Windows Settings That Actually Matter for Gaming
Windows 11 ships with several gaming-relevant toggles scattered across Settings. These are the ones worth your time:
- Game Mode: Settings > Gaming > Game Mode — turn it On. It prioritises game processes and suppresses Windows Update restarts mid-session.
- Hardware-Accelerated GPU Scheduling: Settings > System > Display > Graphics > Default graphics settings — turn it On, then reboot. It lets the GPU manage its own memory more efficiently; most modern systems gain a little, some gain a lot.
- Power mode: Settings > System > Power — set to Best performance. The “Balanced” and power-saver modes throttle your CPU exactly when games need it most. On laptops, keep the charger plugged in while gaming.
- Variable refresh rate: If your monitor supports FreeSync or G-Sync, enable it in the same Graphics settings page and in your GPU control panel. It won’t raise your FPS, but it makes lower FPS feel far smoother.
- Disable fullscreen optimisations per game if needed: Right-click the game’s exe > Properties > Compatibility. Leave it on normally; only disable if a specific game misbehaves.
We’ve covered the full Windows tuning pass — debloating background services, startup apps, and notification interruptions — in our dedicated guide on optimizing Windows 11 for gaming.
Kill Background Resource Hogs
Games compete with everything else running on your PC. The usual suspects:
- Browsers: Chrome or Edge with dozens of tabs can eat 2–4 GB of RAM and noticeable CPU. Close them while gaming.
- Launchers and overlays: You don’t need Steam, Epic, Discord, and GeForce Experience overlays all active at once. Keep the ones you use; disable the rest.
- RGB and peripheral software: iCUE, Synapse, Armoury Crate, and similar tools are surprisingly heavy. Set your lighting once, then close them — or set them not to start with Windows.
- Windows startup apps: Task Manager > Startup apps — disable anything you don’t need within a minute of booting.
- Antivirus scans: Schedule full scans for when you’re asleep, and add your games folder to the exclusion list if your antivirus allows it.
If background usage alone pins your processor, read our guide on fixing high CPU usage while gaming — a maxed-out CPU causes stutter no graphics setting can fix.
In-Game Settings: What to Lower First
Not all graphics settings cost the same. When you need more FPS, lower these first — they give the biggest gains for the smallest visual loss:
| Setting | Performance cost | What to do |
|---|---|---|
| Ray tracing | Very high | Turn off unless you have a high-end RTX/RX card |
| Render resolution / resolution scale | Very high | Use DLSS/FSR/XeSS “Quality” mode instead of lowering resolution manually |
| Shadows | High | Drop from Ultra to Medium — barely noticeable in motion |
| Volumetric fog / clouds | High | Medium or Low |
| Ambient occlusion | Medium–High | SSAO instead of HBAO+ if offered |
| Anti-aliasing | Medium | Use DLAA/TAA that ships with upscaling rather than MSAA |
| Texture quality | Low (costs VRAM, not FPS) | Keep High if you have 6 GB+ VRAM; lower only if you see texture pop-in |
| View/draw distance | Medium (CPU-heavy) | Lower if CPU-limited |
The single biggest win on modern hardware is upscaling: NVIDIA DLSS, AMD FSR, or Intel XeSS render the game at a lower internal resolution and reconstruct it smartly. “Quality” mode typically looks nearly identical to native while delivering 30–60% more FPS. Always enable it before touching anything else.
Also cap your frame rate a few FPS below your monitor’s refresh rate (in-game limiter or the GPU control panel). An uncapped frame rate wastes power, adds heat and noise, and causes frame-time spikes that feel like stutter. Speaking of stutter, shader compilation hitches are a separate beast — if your game freezes for a split second when new effects appear, see how to fix shader compilation stuttering.
Storage, Thermals, and RAM: The Hardware Basics
Move games to an SSD. This is the cheapest meaningful upgrade in PC gaming. An SSD won’t raise your average FPS much, but it slashes loading times and eliminates the hitching that happens when games stream textures from a slow hard drive. A 1 TB SATA SSD is enough; NVMe is nicer but not required.
Check your temperatures. CPUs and GPUs throttle themselves when hot — a dust-clogged cooler can quietly cost you 10–20% performance. Use HWMonitor or your GPU vendor’s tool: sustained temps above 90°C on CPU or 85°C on GPU under load mean it’s time to clean dust filters, reapply thermal paste, or improve case airflow.
RAM configuration matters. Two sticks in dual-channel mode (slots 2 and 4 on most motherboards) perform notably better than a single stick. And if you’re still on 8 GB, upgrading to 16 GB is one of the best value upgrades for stutter-free gaming.
Power supply headroom. If your GPU usage mysteriously drops under load, an undersized or ageing PSU can be the cause — see how to fix GPU usage dropping while gaming.
Measure Before and After
Don’t tune blind. Pick one demanding game, note your FPS in a repeatable scene (same location, same settings), make one change, and retest. Our guide on how to check FPS in PC games covers the built-in counters in Steam, GeForce Experience, and AMD Software so you can track real numbers. A change that doesn’t move the needle gets reverted — that’s how you end up with settings that are actually faster, not just different.
When It’s Time to Upgrade (and When It Isn’t)
Software tuning has limits. Consider an upgrade when:
- Your GPU is several generations old and can’t run current games at your monitor’s native resolution even on low settings.
- You have 8 GB of RAM and it’s constantly full.
- You’re still gaming from a mechanical hard drive.
Don’t upgrade when: a single badly optimized game runs poorly (that’s the game’s problem — check its forums and patches first), or when your FPS is already above your monitor’s refresh rate (you literally cannot see the difference).

Frequently Asked Questions (FAQs)
How can I improve PC gaming performance for free?
Update your GPU driver, enable Game Mode and Hardware-Accelerated GPU Scheduling, set power to Best Performance, close background apps, enable DLSS/FSR/XeSS upscaling, and lower shadows and ray tracing first. These cost nothing and typically deliver the biggest gains.
Does more RAM increase FPS?
Only if you don’t have enough. Going from 8 GB to 16 GB can fix stuttering and raise minimum FPS noticeably. Going from 16 GB to 32 GB does almost nothing for gaming alone — save that money for content creation workloads instead.
Will overclocking my GPU help?
A mild overclock typically adds 3–8% FPS — measurable, but small next to what driver updates and settings changes give you. It also adds heat and instability risk. Undervolting is often the smarter move: same performance, lower temperatures and noise.
Why do I get low FPS even though my PC is new?
The most common reasons: the monitor is plugged into the motherboard instead of the graphics card, the game is running on integrated graphics (check Windows Graphics settings per app), drivers were never installed after a fresh Windows setup, or the power plan is throttling the CPU. Check these before assuming the hardware is at fault.
Does Game Mode actually do anything?
On modern Windows 11, yes — modestly. It prioritises the game’s CPU and GPU access and blocks disruptive background activity like update restarts. It’s one toggle with no downside, so there’s no reason to leave it off.
Should I use a “game booster” app?
Most do nothing you can’t do yourself in two minutes — they close background processes and call it optimization. Worse, some bundle ads or unwanted software. Stick to the manual steps in this guide; they’re the same actions, without the middleman. And avoid anything from an unofficial download site promising “FPS unlockers” — those are a common malware vector.
The Bottom Line
Improving PC gaming performance is a process of elimination, not a shopping trip: find your bottleneck, update drivers, fix Windows settings, clear background hogs, enable upscaling, and lower the expensive settings first. Measure with an FPS counter as you go so every change earns its place. Most systems pick up 20–40% smoother gameplay from software tweaks alone.
