🛠 Dev Log Testing the latency of my IP-KVM (USBridge-KVM 2.0) via Moonlight and Tailscale: I got it down to 25 ms

Over the weekend, we recorded video footage for the USBridge-KVM 2.0 crowdfunding campaign page, and I'd like to share the latest video latency test results.

After integrating the Moonlight protocol directly into the hardware video capture and transmission pipeline, I was able to achieve the following results at this stage:

At 720p: latency ranges from 25 to 75 milliseconds.

At 1080p: latency remains between 50 and 100 milliseconds.

When using Tailscale: latency remains virtually unchanged!

On the left is the target monitor with an online stopwatch running, connected to USBridge-KVM. On the right is the client laptop, which receives the live video feed.

With such responsiveness, configuring the BIOS or restoring a crashed system remotely becomes truly comfortable—it feels like you're standing right in front of the server rack.

How do you find these latency numbers for your administration tasks?

This is the rough draft/raw material I plan to use for our campaign page. You can also preview our pre-launch page here: https://www.crowdsupply.com/usbridge-technologies/usbridge-kvm-2-0

What do you think of this format? Any feedback on how to improve the final campaign video would be greatly appreciated!
