Is it a Virus?
✔ NO - Safe
Found in C:\Program Files (x86)\RivaTuner Statistics Server or C:\Program Files\RivaTuner Statistics Server
Warning
RTSS may spawn multiple overlay threads per GPU
RTSS can show per-game overlays; excessive instances are uncommon and may indicate misconfiguration
Can I Disable?
✔ YES
RTSS can be disabled from MSI Afterburner, from Windows Startup, or within RTSS itself by turning off overlays
What is RTSS.exe?
RTSS is the executable for RivaTuner Statistics Server, a lightweight overlay and FPS control utility. It runs alongside games to render an on-screen display, cap frame rates, and monitor hardware sensors. RTSS is commonly bundled with MSI Afterburner.
RTSS uses driver hooks to render an on-screen display and enforce per-app FPS caps without altering game code, collecting GPU/CPU sensor data via supported APIs while remaining lightweight and independent of the game.
Quick Fact: RTSS integrates with graphics drivers to provide accurate FPS counting and per-game overlays with minimal overhead.
Types of RTSS Processes
- RTSS System Monitor: Core background process that handles FPS limiting and data collection
- Overlay Renderer: Renders the in-game overlay on supported APIs (DirectX/OpenGL)
Is rtss.exe Safe?
Yes, rtss.exe Safe when it's the legitimate file from TechPowerUp downloaded from official sources.
Is rtss.exe a Virus or Malware?
The real rtss.exe is NOT a virus. Malware sometimes disguises itself using similar names to trick users.
How to Tell if rtss.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files (x86)\RivaTuner Statistics Server\RTSS.exe or C:\Program Files\RivaTuner Statistics Server\RTSS.exe. Any rtss.exe elsewhere is suspicious.
- Digital Signature:: Right-click the file in Explorer → Properties → Digital Signatures. Should show a certificate from TechPowerUp.
- Resource Usage:: Normal usage is 0-5% CPU and 10-50 MB memory. Constant high usage or activity when not gaming is suspicious.
- Behavior:: RTSS should run when you start a game or MSI Afterburner launches. If it starts without user action or a legitimate overlay, investigate.
Red Flags: If rtss.exe is located in unusual folders (like Temp, AppData, or System32), runs when Windows starts without consent, lacks a valid digital signature, or uses unusual resources constantly, scan with antivirus software immediately. Beware of similarly-named files such as "rtass.exe" or "rtss32.exe" from untrusted sources.
Why Is RTSS Running on My PC?
RTSS runs to manage in-game overlays, FPS caps, and hardware sensor readouts. It hooks into graphics APIs to render data without altering game code, and can be configured to start with Windows or MSI Afterburner.
Reasons it's running:
- Active Overlay in Games: RTSS is actively rendering an in-game overlay and enforcing per-game FPS caps while you play.
- Background Hardware Monitoring: RTSS collects sensor data (temperature, clocks, fan speeds) for display in the OSD.
- Startup and Background Services: RTSS can be configured to launch at Windows startup or with MSI Afterburner for convenience.
- Driver/API Support: RTSS uses driver hooks to support DirectX/OpenGL/Vulkan overlays and maintain compatibility with newer game engines.
- Performance Tuning: RTSS manages per-app FPS caps to help reduce micro-stutters and maintain consistent frame timing.
Can I Disable or Remove RTSS?
Yes, you can disable RTSS. It is optional; you can stop its services and uninstall it if you prefer another overlay solution.
How to Stop RTSS
- End RTSS from Task Manager: Open Task Manager, locate RTSS.exe, and choose End Task; repeat for any dependent processes.
- Disable Startup: Task Manager → Startup tab → Disable RivaTuner Statistics Server
- Disable Overlays in MSI Afterburner: Open MSI Afterburner settings and uncheck 'Show On-Screen Display' for all profiles
- Stop Background Service: If RTSS is installed as a service, stop it from Services.msc or set startup to Manual
- Remove from System Startup: Delete RTSS entries from startup folders or uninstall RTSS from Apps & Features
How to Uninstall RTSS
- ✔ Windows Settings → Apps → Apps & Features → RivaTuner Statistics Server → Uninstall
- ✔ If bundled with MSI Afterburner, uninstall Afterburner (or untick RTSS during installation) and remove RTSS components
- ✔ Delete leftover files: C:\Program Files (x86)\RivaTuner Statistics Server and C:\Program Files\RivaTuner Statistics Server
Common Problems: Overlay Not Visible or FPS Cap Not Applying
If RTSS overlay is missing or FPS limits aren’t taking effect, try the following common fixes to restore proper operation.
Common Causes & Solutions
- Overlay Not Enabled for the Game: Add the game to RTSS and ensure the overlay is enabled for the specific executable.
- FPS Cap Not Applying: Set a concrete FPS limit in RTSS, enable per-app limits, and try disabling V-Sync or Triple Buffering if needed.
- Startup or Access Conflicts: Disable RTSS from auto-start or check MSI Afterburner integration; ensure RTSS is not blocked by antivirus.
- Conflicts with Other Overlays: Disable Discord/Steam overlays or Nvidia GeForce Experience overlay to avoid conflicts.
- Driver API Compatibility: Update GPU drivers and RTSS to the latest version; ensure DirectX/OpenGL/Vulkan support is active.
- Incorrect OS Settings: Run RTSS as admin and adjust OS-level permissions; ensure Game Mode or fullscreen optimizations are properly configured.
Quick Fixes:
1. Quick Fixes:
2. 1. Open RTSS and confirm the target game is added and enabled
3. Restart RTSS and the game to apply changes
4. Update GPU drivers and MSI Afterburner integration
5. Disable conflicting overlays (Discord, Steam, Nvidia overlay)
6. Test with a simple game to verify FPS cap and OSd rendering
Frequently Asked Questions
Is RTSS safe to use?
Yes, RTSS is safe when downloaded from TechPowerUp or bundled with MSI Afterburner. Verify the installation path and signature before use.
What does RTSS do exactly?
RTSS provides an on-screen display (OSD), per-app FPS caps, and hardware sensor readouts for supported GPUs and APIs.
Can RTSS cause high CPU or memory usage?
Rarely; misconfiguration or conflicting overlays can raise overhead. Check active apps, update RTSS, and disable unnecessary overlays.
How do I enable RTSS overlays for a game?
Add the game executable to RTSS, enable the overlay, and configure the FPS cap; ensure the game is not running with other conflicting overlay software.
How to disable RTSS at startup?
Disable RTSS in Task Manager Startup tab or uninstall RTSS from Settings → Apps. You can also disable the 'Start with Windows' option in RTSS if available.
Where is RTSS installed and how do I uninstall it?
RTSS is usually installed under C:\Program Files (x86)\RivaTuner Statistics Server or C:\Program Files\RivaTuner Statistics Server. Uninstall via Settings → Apps or MSI Afterburner integration.
