I have a series of videos on my youtube channel outlining desync, the channel is called Project Zell and the videos are titled, objection.
Latency is caused by time taken between your connection and the server, vs the other players time between the server and other players. This is displayed in game via the ping. Speed between your connection and the server. It was more easily distinguished back when halo was host based, not server based.
Desync occurs when there is latency from the server back to your client. This causes issues like bullets going through walls, rockets de spawning mid flight, back taps not registering and having no effect, bars on captured hills jumping/ moving at an irregular pace, oddball time jumping.
The server side issues and client side issues are desync.
There’s a video of two people in the same lan game using the warthog, the driver and gunner have two different perspectives on where they are in the game at the same time.
There’s plenty of evidence and an entire article from 343i on the topic to back the fact it does exist. I have experienced desync, most of the people on the forums have, HCS players have, it has been streamed and documented thousands of times at this point.
Kudo’s to you for not running into it yourself, that must be nice.
However, that’s not to say someone in any of the games you have played- either on your team or against you, have not encountered it.
This topic and the OP have baited the entire forum with this thread, and im unsure why it hasn’t been locked as of yet, but the moderators seem to have different preferences on what they will lock/ hide and what they wont based on who’s posting.
All in all, the drop pod (patch) slated to fix desync will be very welcome for the majority of the halo playerbase at this point.
