How to Improve PC Gaming Performance: 12 Proven Fixes (2026)

# How to Improve PC Gaming Performance: 12 Proven Fixes (2026)

By Daniel Rozin | A Versus B | October 7, 2026

Low frame rates, lag spikes, and micro-stuttering are frustrating — but they're almost always solvable without buying new hardware. The majority of gaming performance issues in 2026 are caused by misconfigured Windows settings, outdated drivers, background processes eating resources, and power plans that throttle your GPU. This guide covers the 12 most effective fixes, in order from easiest to most involved.

1. Update Your GPU Drivers#

This is step one for a reason. Outdated GPU drivers are the single most common cause of gaming performance problems, and the fix takes two minutes. For NVIDIA cards, download GeForce Experience and hit "Check for Updates." For AMD cards, use AMD Adrenalin. Driver updates often include game-specific optimizations that directly improve FPS in newly released titles.

Don't use Windows Update for GPU drivers — it frequently installs outdated versions. Always download directly from NVIDIA or AMD.

2. Switch to a High-Performance Power Plan#

Windows 10 and 11 default to "Balanced" power plan, which throttles CPU and GPU performance to save electricity. For gaming, switch to "High Performance" or, better, "Ultimate Performance" (available via PowerShell on Windows 10/11 Pro).

Steps:

1. Open Control Panel → Power Options
2. Select "High Performance" (or click "Show additional plans" to reveal Ultimate Performance)
3. If Ultimate Performance is not listed, open PowerShell as Administrator and run: `powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61`

This single change can add 5–15% FPS in CPU-limited games.

3. Disable Xbox Game Bar and Background Recording#

Windows 11 ships with Xbox Game Bar (Win+G) and background game recording enabled. Both consume CPU and RAM while you play. Unless you actively use them, disable them:

1. Go to Settings → Gaming → Xbox Game Bar → toggle off
2. Go to Settings → Gaming → Captures → set "Record in the background while I'm playing a game" to Off

4. Close Background Processes Before Playing#

Open Task Manager (Ctrl+Shift+Esc) before launching your game and end any processes consuming more than 1–2% CPU or 200MB+ RAM. Common culprits: browser windows with many tabs, Discord video, OneDrive syncing, Windows Update running in the background, and antivirus full scans.

For a consistent setup, create a simple batch script that kills these processes on demand — a common trick among competitive players.

5. Set Your Game to High Priority#

In Task Manager → Details tab, right-click your game's process and set priority to "High." This instructs the Windows scheduler to allocate more CPU cycles to the game process. Combined with closing background apps, this is particularly effective for CPU-limited games. Do not set to "Realtime" — that can cause system instability.

6. Enable Hardware-Accelerated GPU Scheduling (HAGS)#

Available on Windows 11 with NVIDIA 30-series or AMD RX 6000-series (and newer), HAGS offloads GPU scheduling from the CPU, reducing latency and improving 1% low FPS metrics (the stutters you actually feel).

Enable it: Settings → System → Display → Graphics → Default graphics settings → toggle on "Hardware-accelerated GPU scheduling." Restart your PC.

7. Check Your In-Game Settings#

Many players leave graphical settings misconfigured. The highest-impact settings to adjust (reduce for FPS gains):

• Shadow quality: Shadows are extremely GPU-expensive. Dropping from Ultra to High often costs nothing visually but gains 10–20 FPS.
• Anti-aliasing: TAA is cheaper than MSAA. DLSS (NVIDIA) or FSR (AMD) can effectively double your FPS with minimal visual cost.
• Draw distance / view distance: In open-world games, this one setting can swing FPS by 30% between Medium and Ultra.
• V-Sync: Disable in-game V-Sync if you're not hitting your monitor's refresh rate — it adds input lag and caps FPS.

8. Use DLSS, FSR, or XeSS#

If your GPU supports it, DLSS 4 (NVIDIA RTX), FSR 4 (AMD), or Intel XeSS is the most impactful single setting you can toggle. These upscaling technologies render the game at a lower resolution and reconstruct it at your native resolution using AI. DLSS 4 Quality mode, for example, renders at roughly 67% of native resolution but outputs near-native image quality — typically with a 40–80% FPS gain.

For the NVIDIA vs. AMD GPU decision, DLSS support is a key differentiator: NVIDIA's implementation is currently more mature than AMD's FSR.

9. Upgrade to an SSD If You're Still on HDD#

If your game is installed on a hard disk drive, loading times and shader compilation stutter will be severe in 2026 games. Modern titles expect SSD-level read speeds (500+ MB/s) for asset streaming. Compare SSD vs. HDD — a 1TB SATA SSD costs under $60 and eliminates one of the most common gaming bottlenecks.

10. Check Your RAM Configuration#

RAM in single-channel mode (one stick) runs at roughly half the bandwidth of dual-channel (two matching sticks in the correct slots). This directly impacts CPU-integrated graphics users, but also affects dedicated GPU performance in memory-bandwidth-sensitive games.

If you have two RAM sticks, ensure they're in slots A2 and B2 (check your motherboard manual — typically the 2nd and 4th slots from the CPU). Also check whether your RAM is running at its rated XMP/EXPO speed in BIOS; many systems default to a lower speed (2133 or 2400 MHz) even with DDR5-6000 installed.

11. Clean Your PC — Literally#

Thermal throttling is a silent FPS killer. When your CPU or GPU overheats (typically above 95°C for CPUs, 85°C for GPUs), it automatically reduces clock speeds to prevent damage. Opening your case and blowing out dust from fans, heatsinks, and vents can drop temperatures 10–20°C. While you're in there, check whether your CPU cooler thermal paste has dried out — reapplying it takes 10 minutes and can recover 5–15°C of thermal headroom.

12. Monitor Your Bottleneck#

Before doing anything else, identify where your system is actually bottlenecked. MSI Afterburner (free) overlays CPU and GPU usage in-game. If your GPU is at 99% and CPU is at 30–50%, you're GPU-limited — focus on lowering graphical settings or upgrading the GPU. If your CPU is at 90%+ and GPU is under 70%, you're CPU-limited — focus on closing background processes, overclocking, or upgrading the CPU.

Knowing your bottleneck prevents the common mistake of buying a new GPU when the real problem is a 10-year-old CPU.

FAQ#

What is the fastest way to boost FPS without buying new hardware?

The fastest free improvements are: switch to High Performance power plan, update GPU drivers, disable background recording (Xbox Game Bar), and optimize in-game shadow and resolution scaling settings. Together, these can add 20–40% FPS in common scenarios.

Does more RAM improve gaming FPS?

For most gaming scenarios, 16GB DDR4 or DDR5 is the sweet spot — more RAM typically does not improve FPS unless a specific game requires it (some newer AAA titles recommend 32GB). However, running in single-channel mode or at a slower-than-rated speed does meaningfully reduce performance. DDR4 vs. DDR5 matters more for bandwidth than pure capacity.

Why do I get good FPS but still feel lag?

High FPS with perceived lag is almost always input latency — the delay between your mouse click and the on-screen response. Enable hardware-accelerated GPU scheduling, disable V-Sync (or use G-Sync/FreeSync instead), and check that your game is running at your monitor's actual refresh rate. Input lag is also worsened by certain USB polling rates and wireless peripherals.

Does reinstalling Windows improve gaming performance?

It can, particularly on machines that have been running for years without a clean install. A fresh Windows install eliminates software cruft, broken registry entries, and accumulated background processes. It's a last resort — try all software optimizations first — but it does reliably recover performance on heavily used systems.
