01.Why Limit FPS if my PC is Powerful?
In 2026, having a high FPS (e.g., 300 FPS) doesn't always mean the game is fluid. What truly matters for image smoothness is **Frametime** (the time each frame takes to be rendered). If your FPS fluctuates between 200 and 300, you'll feel micro-stutters. Limiting the FPS to a fixed value (e.g., 141) ensures that all frames are delivered at consistent intervals, eliminating stuttering and reducing GPU heat.

02.1. RivaTuner (RTSS): Millisecond Precision
RivaTuner is considered the most precise framerate limiter in the world:
- Open RivaTuner Statistics Server (it installs alongside MSI Afterburner).
- In the 'Framerate limit' field, type your desired value (e.g., 141).
- Change 'Framerate limit mode' to 'Async' (for less lag) or 'Front-edge' (for more precision).
- RTSS ensures that frame delivery is millisecond-perfect, resulting in a perfectly flat frametime graph.
03.2. Via NVIDIA Control Panel (Quick & Easy)
Without installing extra software:
1. Right-click on your desktop > NVIDIA Control Panel.
2. Go to 'Manage 3D settings'.
3. Look for 'Max Frame Rate'.
4. Set it to 'On' and choose your value.
Tip: If you use G-Sync, limit your FPS to 3 frames below your monitor's Hertz (e.g., 141 FPS for a 144Hz monitor) to ensure G-Sync remains active.
04.3. RivaTuner vs NVIDIA: Which to Choose?
- Use RivaTuner if you feel the game is "shaking" or "juddering" even with high FPS. It is superior for overall image stability.
- Use the NVIDIA Control Panel if you play competitively (Valorant, CS2). As of 2026, NVIDIA's limiter has slightly lower input lag than RivaTuner, which can make a difference in reaction-based shots.
