System overhead—the CPU, memory, and disc resources consumed by background services—is a critical factor for any gaming PC. Whilst these services are useful for everyday computing, they can reduce frame rates (FPS), increase input lag, and contribute to overheating during intense gaming sessions.
This guide shows you how to optimise your gaming PC’s performance by safely disabling unnecessary Windows background services. You’ll learn how to identify resource-hungry processes, minimise unnecessary overhead, and properly configure essential features like Windows Game Mode and
OMEN Gaming Hub. These techniques work whether you use an
HP OMEN desktop, HP OMEN gaming laptop, or a custom-built system featuring Intel, AMD, or NVIDIA components, helping you achieve smoother gaming performance without compromising system stability.
What Are Background Services and How They Affect Gaming
Windows relies on dozens of background services and applications to keep your system running smoothly. Whilst many are critical for security and hardware stability, not all are essential for gaming. Background processes compete with your games for vital resources like CPU, RAM, and disc bandwidth—all essential for achieving peak gaming performance.
For gamers, too many active services can cause:
- Reduced FPS and fluctuating frame pacing
- Increased input lag that affects reaction time
- Higher system temperatures from extra workload
Common resource-draining services include OneDrive sync,
Microsoft Copilot, telemetry collectors, and software updaters. Disabling these can lower system overhead whilst maintaining stability.
Pre-Optimisation Assessment: Check Your System First
Before making any changes, establish a performance baseline.
Monitor Current Usage
Open Task Manager (Ctrl + Shift + Esc) and check CPU, RAM, and disc usage to identify which services consume the most resources.
Create a Restore Point
Set up a System Restore Point so you can roll back changes if needed.
Measure Performance
Launch your favourite game and log FPS, CPU/GPU usage, input lag, and temperature. Tools like MSI Afterburner or the
built-in OMEN Gaming Hub monitoring features provide real-time data.
This benchmark lets you measure performance improvements after disabling non-essential services. The goal is to optimise your gaming PC for performance without compromising system stability.
Essential Services You Should Never Disable
Whilst disabling some services can free up resources, certain Windows services are critical for stability and security. When optimising your gaming PC, leave the following running:
- Security services: Windows Defender, Windows Firewall
- Hardware-dependent services: Plug and Play, Windows Audio
- GPU drivers: Intel, NVIDIA, AMD graphics drivers and associated software
Disabling these can cause crashes, loss of audio, network issues, or system failure. When in doubt, leave a service enabled.
Safe-to-Disable Services for Gaming Optimisation
Once essential services are secured, you can disable or adjust less critical services.
How to Disable Services
- Press Windows + R, type services.msc, and hit Enter
- Right-click the service you want to modify and select Properties
- Under Startup type, choose Manual or Disabled
Services Safe to Disable for Gaming
To free up system resources and enhance your gaming experience, consider disabling these background services:
Windows Search: Constantly indexes files, consuming CPU and disc resources. Disabling it won’t impact gameplay but will free up valuable resources.
Superfetch / SysMain: Though designed to preload applications into RAM, this service often interferes with gaming workloads, decreasing performance.
Xbox Services: Including
Xbox Game Bar and Game DVR, these services enable background recording that can introduce input lag during gameplay.
OneDrive Sync: Syncs files to the cloud but can consume significant bandwidth and cause intermittent CPU spikes, impacting gaming performance.
Print Spooler: If you don’t print from your gaming PC, this service is unnecessary and can be safely disabled.
Optimisation Impact
Disabling these services can reduce CPU usage significantly, ease RAM demand, and free up disc bandwidth, resulting in steadier frame rates and reduced input lag. Advanced users may prefer setting services to Manual rather than Disabled, so they launch only when required.
Advanced Windows Gaming Optimisations
Beyond disabling background services, these
Windows and OMEN tweaks can further improve performance:
Windows Game Mode
Prioritises CPU and GPU resources for active gameplay.
Power Plan Settings
Switch to High Performance mode to prevent throttling.
Visual Effects
Under System Settings → Performance, select “Adjust for best performance” to reduce overhead.
OMEN Gaming Hub Features
- Track real-time temperatures and CPU/GPU loads
- Customise fan curves for efficient cooling
- Set process priority to ensure games run smoothly
For OMEN PC owners, combining these optimisations with Intel processors, NVIDIA GPUs, and
AMD Ryzen technologies delivers a competitive edge in demanding AAA titles.
Frequently Asked Questions About Gaming PC Optimisation
Does Disabling Services Improve FPS?
Yes, disabling unnecessary services can free up CPU and RAM, resulting in higher FPS and smoother gameplay, especially in resource-intensive AAA games. When you reduce system overhead, more resources become available for your game, leading to measurable performance improvements.
Which Background Processes Most Affect Gaming Performance?
Services that sync files (OneDrive), update software (auto-updaters), or handle telemetry are the most common culprits. Windows Search and Superfetch/SysMain can also consume significant resources during gameplay, particularly on systems with mechanical hard drives or limited RAM.
Can I Safely Restore Services if Something Breaks?
Absolutely. Set the startup type back to Automatic or Manual in Services, or use your restore point. This is why creating a System Restore Point before making changes is crucial—it provides a safety net for experimentation.
Will This Void My HP Warranty?
Disabling non-essential services does not affect your HP warranty. These are standard Windows configuration changes that don’t modify hardware or firmware. For complete details about warranty coverage, check your warranty documentation or visit the
HP support website.
How Often Should I Review System Services for Optimal Gaming?
We recommend checking every two to three months, or after major Windows updates. Windows updates can re-enable certain services or introduce new background processes that may impact gaming performance.
Should I Disable Windows Defender Whilst Gaming?
No, we strongly recommend keeping Windows Defender active. Modern security threats can compromise your system and personal data. Windows Defender is optimised to minimise impact on gaming performance whilst providing essential protection.
Maximising Performance with the Right Hardware
Whilst software optimisation is crucial, pairing it with the right hardware delivers the best results. HP’s
gaming desktops are engineered with advanced cooling systems and intelligent component selection to handle demanding workloads.
For gamers seeking the ultimate experience, the OMEN range provides cutting-edge performance. The
OMEN 16L Gaming Desktop features NVIDIA GeForce RTX 5060 SUPER graphics, delivering exceptional frame rates even with background services running. Its tool-less design makes upgrades straightforward, allowing you to adapt your system as gaming demands evolve.
For those prioritising value without compromising capability, the
Victus TG02-0039na Gaming Desktop offers impressive performance with NVIDIA GeForce RTX 4060 Ti graphics. It provides 9 USB ports and Bluetooth connectivity, making it versatile for both gaming and productivity.
Monitoring Your Optimisation Results
After implementing these changes, monitor your system’s performance over several gaming sessions. Use the OMEN Gaming Hub or third-party tools to track:
- Average and minimum FPS in your favourite games
- CPU and GPU utilisation percentages
- System temperatures under load
- Input lag measurements
Compare these metrics to your baseline readings. Most users experience a 5-15% improvement in FPS and noticeably reduced input lag, particularly on systems with limited RAM or older processors.
