Rocket League: the FPS cap that actually lowers input lag
Uncapped FPS feels faster and plays worse. Here is the cap to set for your refresh rate, and why frame time matters more than peak FPS.
Rocket League will happily render 300 FPS on modest hardware, which makes it tempting to leave the frame rate uncapped. It is also one of the easiest ways to make a competitive game feel worse. What you feel as "responsiveness" is not your average frame rate — it is the consistency of the time between frames, and uncapped rendering makes that time erratic.
Why a cap slightly below your refresh rate wins
With G-SYNC or FreeSync active, a cap a few frames under the panel's refresh rate keeps the variable refresh window engaged instead of letting the frame rate cross into tearing or into VSync's buffering. On a 144Hz monitor that means roughly 141 FPS; on 165Hz, 162; on 240Hz, 237. The number is not magic — it is just far enough below the ceiling that you never bump into it.
The payoff is consistency. A locked 120 FPS with flat 8.3ms frame times feels more responsive than 150–200 FPS with erratic pacing, because the delay between your input and the pixel updating stays predictable.

- Use exclusive fullscreen. Borderless and windowed run through the Windows Desktop Window Manager, which adds latency.
- Disable in-game VSync. It adds at least one to two frames of input lag minimum.
- Turn on NVIDIA Low Latency Mode (Ultra) or AMD Anti-Lag to shorten the render queue — worth roughly 5–15ms.
- Turn Radeon Chill off for competitive play. It varies frame rate and hurts exactly the consistency you are chasing.
- Use a wired controller. Wireless adds roughly 4–8ms over USB.
Rocket League is a game where you read the ball at speed, so the effects you can delete for free are the ones to delete: motion blur, depth of field, lens flares and light shafts all cost frames and add nothing to readability. Cap your frame rate, keep the image clean, and the car does what you told it to.
One more thing worth ruling out
After a driver reset, Windows sometimes returns a high-refresh monitor to 60Hz. If Rocket League feels choppy while your FPS counter looks normal, open Windows display settings and confirm the panel is still at its intended refresh rate — and that the cable is connected to the GPU rather than the motherboard. That single check resolves a surprising number of unexplained stutter reports.
