Here you will find the result of my digital FPV system latency testing.
More information on test methods and these charts can be found in the below videos.
2026 Latency Update with Caddx Ascent & BetaFPV ArtLynk
All Digital FPV Systems
This is the current latency testing results from all systems in late 2025 and 2026. Some of the latency numbers in Avatar HD have increased as an example over time a small amout. This is nothing I am concernd about.
Caddx Ascent & ArtLynk
Caddx Avatar HD and Ascent Alone
DJI FPV & O3 All Modes ( O4 Listed Sepertatly Below)
Below is a chart showing the latency of the DJI Digital FPV System as well as DJI O3 in each recording mode.
The recording mode selected in DJI O3 directly affects the latency and the frame rates available, this chart shows the modes and their affect.
DJI O4
Overall O4 in lowest latency mode 100fps offers the same latency as O3, In other frames rates it is a little lower than DJI O3 however still not as low as the original DJI Digital FPV System.
Note: This info does not incluide DJI Race Mode that was added after release, this is in the main chart at the top.
Avatar HD – Older Data
Newer testting has seen a slight incrwase in Avatar latency with the Goggles X compared to the oroginal CaddX goggle and release Firmware.
HDZero
Older test Data – Updated above.
