Frequently Asked Questions
If frame rate reaches or exceeds your monitor's refresh rate, G-Sync turns off and standard V-Sync takes over, adding 1 to 2 frames of input latency. Capping 3 to 4 FPS below (e.g. 237 FPS on 240Hz) keeps G-Sync continuously active within its variable range.

About This Calculator
Calculate optimal FPS caps (e.g. -3 FPS below refresh rate) for G-Sync and FreeSync variable refresh rate displays to eliminate screen tearing without adding V-Sync input lag.
How to Use the VRR FPS Cap Calculator
- 1Enter your monitor's max refresh rate in Hertz (e.g. 144Hz, 240Hz, 360Hz).
- 2View your recommended FPS cap value for NVIDIA Control Panel / RTSS.
G-Sync & Reflex Input Latency Mechanics
Optimal VRR Cap = Refresh Rate - 3 FPS (for 144Hz-240Hz) or -4 FPS (for 360Hz+). This prevents frame time variance from exceeding the refresh window.
Worked VRR FPS Cap Examples
Example: 240Hz G-Sync Monitor
- Apply -3 FPS rule: 240 - 3 = 237 FPS cap.
Set FPS Cap = 237 FPS in NVIDIA Control Panel or RTSS.
Frequently Asked Questions About VRR FPS Caps
Why should I cap FPS 3 to 4 frames below monitor refresh rate with G-Sync?
If frame rate reaches or exceeds your monitor's refresh rate, G-Sync turns off and standard V-Sync takes over, adding 1 to 2 frames of input latency. Capping 3 to 4 FPS below (e.g. 237 FPS on 240Hz) keeps G-Sync continuously active within its variable range.
