Is that normal?

[jokoon]

I tested netfox locally, and I can see some lag.

is that a matter of configuration?

maybe its the FPS, its under the physics tick rate. The FPS is heavy because of graphics or other things I assume because without any connections the game tanks at 200 FPS.

To clarify, the network logic runs at 24 fps in Forest Brawl, and is not dependent on the physics tick rate ( unless configured so ).

Thanks for reaching out @jokoon, let me get back to you on this one. My initial guess is the tickrate - the network loop runs at 24fps, so even on local, there could be an 1/24th second of latency.

Did a bit of testing this morning.

30 hz physics / sync to physics on / vsync on
30 hz physics / sync to physics on / vsync off
30 hz physics / sync to physics off / vsync on
30 hz physics / sync to physics off / vsync off

All tests were performed in windowed mode.

They all seem to drift eventually from the server but 30 hz physics / sync to physics on / vsync off seemed to be the most consistent.

Running physics at 30 fps looks really bad, you get a stop motion effect. I didn't realise Godot wouldn't interpolate - its being worked on though.

@elementbound Given the above your solution makes sense to me. Pin ticks to a reliable clock like the system one and ditch any reliance on loop deltas.

Thanks for the testing @albertok! Here's the draft PR for using the OS clock, let me know what you think and if it still drifts as strongly: #225

[robinreversi]

Tried enabling sync to physics but ran into some other bugs, will let you know once I get these sorted out. Thanks both for the help and the quick turnaround time!

[elementbound]

@robinreversi just updated #225, hopefully it should fix the time drifting even without sync to physics. Feel free to test it as-is and let me know what you find! If you feel like, feel free to leave a review on the PR as well, in case you spot something 🙂

[robinreversi]

Just gave it a try, seems like it worked, thanks!!

[jokoon]

Yes I think the right one is the host, but I am not sure... one the other is the host. Note: it was done on a slow laptop, i5 without GPU, so that might be the issue. No I did not modify that offset.

@jokoon @robinreversi the fix is merged to main! Please feel free to open a new discussion / issue if you encounter any problems.

Thanks @albertok for the investigation and help with the PR!
