RivaTuner vs MSI Afterburner: What Is the Difference & How They Work Together
Updated: September 2026 | Reading time: 5 min read
One of the most frequent questions among PC gamers is: "Are RivaTuner and MSI Afterburner the same software, and do I need both installed?" The short answer is no, they are separate programs, but they are engineered to integrate seamlessly.
Side-by-Side Comparison Table
| Feature / Responsibility | RivaTuner Statistics Server (RTSS) | MSI Afterburner |
|---|---|---|
| Primary Role | Framerate Limiter & OSD Hook Engine | GPU Overclocking & Hardware Telemetry Polling |
| GPU Clock & Voltage Control | No | Yes (Core clock, memory clock, voltage curve) |
| Frametime Pacing & FPS Cap | Yes (Sub-millisecond buffer delay) | Delegated to RTSS |
| DirectX / Vulkan Overlay Rendering | Yes (Handles the actual font & graphics injection) | No (Passes text data to RTSS to render) |
| Custom Fan Speed Curves | No | Yes |
| Can Run Standalone? | Yes (100% independent FPS limiter & OSD) | Yes (Overclocking works without RTSS) |
How They Communicate (The Client-Server Architecture)
MSI Afterburner is the hardware sensor aggregator. It reads your GPU core temperature, power consumption, fan RPM, and CPU load through Windows driver interfaces. However, MSI Afterburner itself has no built-in ability to draw text inside a 3D DirectX 12 or Vulkan game window.
That is where RivaTuner Statistics Server (RTSS) comes in: RTSS is the server and graphics hook. Afterburner hands its text strings to RTSS via shared memory, and RTSS renders the On-Screen Display over the game buffer using its lightweight hook.
Can You Use RivaTuner Without MSI Afterburner?
Yes, absolutely. If you do not care about overclocking your graphics card or seeing hardware thermals, you can run RTSS completely on its own. Standalone RTSS provides:
- The world's most precise framerate limiter (superior to driver limiters and in-game caps).
- Real-time FPS and frametime line graphs.
- In-game screenshot and video recording.
