Improve FPVSIM Performance and Frame Rate
Remove browser frame-rate limits and tune Chrome VSync settings for smoother, lower-latency FPVSIM flying.
Compare and configure the Actual, Quick, and KISS rate systems available in FPVSIM.
What this tutorial covers
This visual tutorial introduces the Actual, Quick, and KISS rate systems available in FPVSIM. It shows where to select a rate model, apply it, and compare the resulting stick feel in flight.
Rate numbers are not interchangeable between systems. Each model maps stick position to commanded rotation differently. Record your current model and values before experimenting, and do not copy a number merely because it appears in the video.
Before changing rates
- Save or capture a screenshot of the current rate model and every value.
- Use the same quad, scene, camera angle, and controller calibration for each comparison.
- Choose a large, familiar practice area where fast rotations can be tested safely.
- Decide what you are evaluating: center-stick precision, maximum rotation speed, or the transition between them.
Compare the rate systems
Open PIDS & RATES
Enter the simulator settings and open the PIDS & RATES panel shown in the video.
Select a rate model
Use the selector to choose Actual, Quick, or KISS rates. Notice that the field labels and numerical interpretation can change with the selected model.
Enter values intentionally
Use values you understand for that specific rate system. If you are converting an existing setup, use a trustworthy rate converter or the documentation for the source and destination models.
Apply and reload
Choose Apply, then reload or reboot the simulator world so the runtime uses the selected settings consistently.
Fly a repeatable sequence
Test slow center-stick corrections, half-stick turns, and a few full-stick rolls or flips. Keep the line and input sequence as consistent as possible.
Change one model at a time
Return to the settings, select the next rate system, apply it, reload, and repeat the same flight. Avoid changing controller calibration or physics settings during the comparison.
Keep the clearest result
Choose the system and values that give you predictable control across the full stick range, then save the final configuration.
Reading the difference
- Center-stick behavior affects small corrections and the precision of a racing line.
- Maximum rate determines how quickly the simulated quad can rotate near full stick.
- The transition between center and maximum rate determines how progressively the response builds.
- A familiar numerical value can produce unfamiliar motion when entered under a different model.
Edited transcript
This video is a music-led visual demonstration with no spoken tutorial narration. The edited tutorial notes below describe the visible sequence and are not a verbatim transcript.
00:00–00:11
The title introduces FPVSIM's Actual, Quick, and KISS rate systems.
00:12–00:31
The PIDS & RATES panel is opened and a rate model is selected with the on-screen selector. The panel displays the controls associated with that model and an Apply button.
00:32–00:52
The simulator returns to flight so the selected response can be observed during turns and rotations.
00:53–01:16
The settings panel is opened again and the selector moves to another of the rate systems named in the title. The visible fields change with the selected model before it is applied.
01:17–01:38
Another short flight demonstrates the resulting control response. Using the same scene makes the visual comparison easier.
01:39–01:50
The final view reinforces the core workflow: select the intended model, apply its values, and evaluate the feel in flight.
Frequently asked questions
Which rate system is best?
There is no universally best model. Use the one you understand and can tune to predictable center-stick response, transition, and maximum rotation speed.
Can I enter the same numbers in Actual, Quick, and KISS?
No. The systems interpret values differently, so the same numbers do not guarantee the same response.
Why should I reload after applying rates?
Reloading or rebooting the simulator world ensures the runtime has adopted the changed setting before you compare it.
How can I make the comparison fair?
Keep the vehicle, controller calibration, scene, camera, and flight sequence constant. Change only the rate model and its intentionally converted values.
Is the music-video demonstration a complete conversion guide?
No. It is a visual feature introduction. Use model-specific documentation or a trusted converter when translating an existing tune.
