Hi Nico,

After having the sim running for a while and traffic being injected for a while, I was trying to track some aircraft movements while cold and dark at KJFK. As I saw the planes move on the ground in the RT app window, I noticed that there is about a 30-second delay between that window showing movement and then the aircraft moving in MSFS 2024. Is that by design? If so, is there a setting in the RT app or in PSXT to reduce that? I have look in both the RT settings as well as the parameters.xml file for PSXT, but nothing jumped out to me.

If not, is there a way to delay the RT app from showing a movement that it has sent to PSXT, so that they can be displayed at roughly the same time?

Thank you.

Are you talking about 14.5?

Yes, the latest version as of yesterday.

I did see the following in the release notes, but was not aware that there would always be a 30-second buffer after the initial load:

In RT App mode, PSXT now uses the same startup buffer mechanism

that was already available in RT Direct.

RT App provides an initial 30-second history buffer (five positions delivered at

once) before switching to real-time data. This allows PSXT to begin

injecting traffic immediately, without waiting for the first 30-second cycle

to complete.

As a result, traffic typically becomes visible about 15 seconds after

connecting to RealTraffic, instead of roughly 45 seconds—bringing RT App

behaviour in line with RT Direct mode.

A new RT App version is required and will be released simultaneously.

There is always (and always have been) a 30 seconds buffer in PSXT, that is needed to build up a vector. 

I thought Balt would have syncronised his display with PSXT in 14.5.

I'll consult Balt about this.

Thank you

I heard back from Balthasar, as I reached out to him about a couple of other questions as well. He has implemented a variable buffer to allow syncing. Currently in a beta version of the app.
