If your Windows 11 PC is underperforming in games, the operating system itself is often the culprit. Microsoft ships Windows 11 with a stack of background services, visual effects, and power settings tuned for battery life and compatibility — not raw gaming performance. The good news: a targeted round of tweaks can unlock meaningful FPS gains without touching your GPU or spending a dollar.
This guide covers the best Windows 11 settings for gaming in 2026, from essential one-click fixes to deeper system optimizations. Every setting listed here has a measurable impact. We’ll also show you what to realistically expect from your hardware tier after applying these changes.
Why Windows 11 Throttles Gaming Performance by Default
Windows 11 ships with several systems that compete with your game for CPU time, memory bandwidth, and power budget:
- Variable Refresh Rate (VRR) and Auto HDR — enabled by default, they introduce latency and overhead even on monitors that don’t support them
- Hardware-accelerated GPU Scheduling (HAGS) — beneficial on modern GPUs, harmful on older ones
- Power plan defaulting to Balanced — caps CPU and GPU clocks to save energy
- Xbox Game Bar and DVR — runs a background capture loop even when you’re not recording
- Nagle’s Algorithm — bundles TCP packets to save bandwidth, adding latency in online games
None of these are bugs. They’re deliberate trade-offs Microsoft made for the average user. Gamers are not average users.
Essential Windows 11 Gaming Tweaks (Do These First)
1. Switch to High Performance or Ultimate Performance Power Plan
This is the single highest-impact change you can make.
Open Settings → System → Power & Sleep → Additional power settings. Select High Performance. If it’s not listed, unlock Ultimate Performance by opening PowerShell as Administrator and running:
powercmdlet -alias cmdlet -alias powercfg -command /duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
Or simply paste this into an elevated PowerShell window:
powershell
powercfg /duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
Refresh the Power Options panel and select Ultimate Performance. On a Ryzen 7 5800X paired with an RTX 3080, this alone delivers 8–15% more average FPS in CPU-bound titles like Cyberpunk 2077 and Baldur’s Gate 3.
2. Disable Xbox Game Bar and Background Recording
Go to Settings → Gaming → Xbox Game Bar and toggle it Off. Then go to Settings → Gaming → Captures and set Record in the background while I’m playing a game to Off.
Game Bar runs a shadow recording buffer at all times. On systems with 16 GB RAM or less, this noticeably impacts 1% low FPS.
3. Enable Game Mode
Despite its subtle name, Settings → Gaming → Game Mode → On tells Windows to deprioritize background processes and prevent driver updates from installing mid-session. Keep this on.
4. Turn Off Hardware-Accelerated GPU Scheduling (If Your GPU Is Older Than RTX 30xx / RX 6000)
HAGS is found at Settings → Display → Graphics → Default graphics settings. On an RTX 3070 or RX 6700 XT and newer, leave it enabled. On a GTX 10-series, GTX 16-series, or RX 5000-series card, disable it — HAGS on older GPUs increases frametimes and hitching.
5. Set Visual Effects to Best Performance
Open Run (Win+R) → sysdm.cpl → Advanced tab → Performance Settings. Select Adjust for best performance. This disables animations, transparency, shadows, and thumbnail previews — cutting CPU overhead by 1–4% in the background, which matters on 6-core and under processors.
Network and Latency Optimizations
For online games, raw FPS is only half the equation. These tweaks reduce network latency and packet jitter.
Disable Nagle’s Algorithm
Open Registry Editor (regedit) and navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces
Find the interface key that matches your active network adapter’s IP address. Inside, create two new DWORD (32-bit) values:
TcpAckFrequency= 1TCPNoDelay= 1
Restart your PC. This forces Windows to send TCP acknowledgments immediately rather than batching them. In titles like Valorant, CS2, and Apex Legends, you’ll see 5–20ms lower average ping.
Prioritize Gaming Traffic with QoS
Go to Settings → Network & Internet → Advanced network settings → More network adapter options. Right-click your adapter → Properties → QoS Packet Scheduler. Confirm it’s checked. Then open Local Group Policy Editor (gpedit.msc) → Computer Configuration → Windows Settings → Policy-based QoS. Create a new policy, set DSCP value to 46, and apply it to your game’s executable.
GPU and Display Settings
Enable Variable Refresh Rate Only If You Have a VRR Monitor
Settings → System → Display → Graphics → Default graphics settings → Variable refresh rate. Enable this only if your monitor is G-Sync or FreeSync compatible. On a standard 60Hz or 144Hz panel without VRR support, this toggle adds overhead for zero benefit.
Set Display Resolution and Refresh Rate Manually
Windows sometimes resets refresh rate after driver updates. Verify it’s correct: Settings → System → Display → Advanced display → Choose a refresh rate. Set it to your monitor’s maximum — 144Hz, 165Hz, 240Hz, or 360Hz depending on your display.
Disable Auto HDR
Unless you specifically want Auto HDR, disable it at Settings → System → Display → HDR → Auto HDR. Auto HDR processes every frame through a tone-mapping shader. On an RTX 4070 this costs roughly 3–6 FPS even in SDR games.
Background Process Cleanup
Open Task Manager → Startup apps and disable everything non-essential: Discord can be launched manually, OneDrive sync has no place during a gaming session, and any RGB lighting software that auto-starts adds CPU overhead.
Additionally, set your Windows Update active hours to cover your gaming window. Go to Settings → Windows Update → Advanced options → Active hours. Set a range that includes your typical play sessions to prevent forced restarts and background download throttling.
Pro tip: Use
msconfig(System Configuration) → Services tab → check Hide all Microsoft services → disable any third-party services you don’t recognize or actively use. Be conservative — disable only what you can identify.

Final Checklist
Run through this list before your next session:
- [ ] Power plan set to High Performance or Ultimate Performance
- [ ] Xbox Game Bar disabled, background recording off
- [ ] Game Mode enabled
- [ ] HAGS setting matched to your GPU generation
- [ ] Visual effects set to Best Performance
- [ ] Nagle’s Algorithm disabled in the registry
- [ ] Display refresh rate verified at maximum
- [ ] Auto HDR disabled (unless intentionally enabled)
- [ ] Startup apps trimmed in Task Manager
- [ ] Windows Update active hours set to avoid gaming windows
These are the best Windows 11 settings for gaming you can apply without modifying hardware or overclocking. Most take under 20 minutes to implement, and the combined effect on frame pacing and minimum FPS is significant — especially on mid-range and budget systems where every background process competes directly with your game.
Apply them once, benchmark the difference, and you’ll rarely need to revisit them. Windows 11 doesn’t reset these settings on its own — they stick across reboots and most major updates.
