I have found that while desynced the lasers in summit 6 do not kill you. This could be why the world records look impossible to pull off. Is this allowed? or is there a way to tell if they should be dead?

@FrikenPorpoise this is the reason that I've supported disallowing desynced mods, since in synced versions of the game it's based on ping and because of that, impossible to consistently dectect if your gim is in the laser. It isn't the reason that the records look impossible to pull off, you can look at the Release Physics WR which is synced and the lasers still don't look right. This is due to the server thinking that you are at a slightly different position than it looks like on your side. The higher the ping, the more off the server thinks you are. Desynced runs attempt to recreate this ping effect, however they can't recreate what actually happens in the normal state of the game.

To answer your question, normally desync mods give you a notification saying that you hit a laser or will respawn you back to the previous summit, but they often don't work which may cause nothing to happen when colliding with a laser.

In reality, it isn't very important considering there aren't many active competitive players on this game, as desynced mods give many conveniences to runners. Your run would probably be judged by seeing if you obviously hit a laser, and if not it would still be verified.

There should be a message that shows up whenever you are supposed to get hit. The lasers synced are reliant on ping however so this system isn't always completely accurate, unfortunately, but it is the best we can do for these kinds of cases.

I found out that if you have the DLDTas enabled, laser don't kill you or message you

So, to be clear, if I were to do a run where I hit lazers, but it wasn't obvious and the mod didn't give a message. It would be verified?

Also, the mod i'm using has never given any message or anything close to that (I'm using savestates mod to desync)

IDK about that maybe they count the frames where you hit the laser but I'm not the mod team so I don't know. For me savestates respawns me. (Don't use DLDTas)
