R-27T & R-73 Desync in MP

[Cmptohocah]

I was just wondering: anyone knows what is the issue here with the IR missiles in multiplayer? It seems that IR missiles suffer heavily from some sort of desync or what ever is causing them to go dumb from even 2km away. As the video shows, SARHs don't have this issue.

This isn't desync, at least I don't think so.

The first shot, even eeeeeh the second I was like 'ok, guy came off AB and missile lost track' but that's really not right, the following missiles should have tracked.  Rmin is either not or barely a factor in any of those launches as well.

 

Track from both vehicles is needed ... I have no idea how you can reproduce this.   It's almost as if the seekers either are not cooled OR not cued properly OR by mistake they've been turned into rear-aspect only missiles OR the game consider this aircraft dead already for some reason.

 

Can you run an SP test with similar ranges and maneuvers?   You can set the target to invincible and no reaction to threats and replicate the maneuvers by using the aerobatic Mission Editor waypoint settings.

... but before you do all that simple test with the target flying a simple 2-3 WP flight set to invincible and no reaction to threats.

Does this happen with all aircraft types as target?

If you watch the recording you can see that the speed does not change much, so I would rule out the AB. Maneuvering was minimal and no flares were used. A part from shots being fired from the front hemisphere it was a perfect opportunity to hit. Ranges were from 11km down to 1.3km so well above the Rmin. That last barrage of 73's was me trying to see what will eventually happen. This is not the first time such a thing has happened, but I usually have a habit of firing only one to two missiles. This time I wanted to test what the hell is going on, and hence why I sent all of the IRs. After the 27R left the rail, I had a feeling it would hit, which they did. So this leads me to believe that some sort of MP+IR combo is to blame.

 

There is no way this can happen in SP, and I suspected some MP bug since none of them tracked at all. Except for the very first 27T, the rest just flew straight.

When it comes to target aircraft, I'm under the impression that FA-18 and F-16 suffer from this as I usually have no problem hitting F-15s even when they maneuver and flare. Heck, I had a double kill with 27Ts from 25km, but I said those were Eagles. One didn't maneuver at all (first kill), but his wingman started a split-s and flaring, but was also hit.

I will do a SP replica and also try to record the entire MP encounter from within the cockpit, if possible.

The reason I'm talking about the track is that the track is what ED uses to actually debug.    The video has a little more value than the tacview because it's possible to observe how the systems are operating, but the track is the only thing that would permit software debugging.

 

Edit:  I really don't know when I'll have time but I can try to help you reproduce this.  If you can't reproduce in SP we can attempt to reproduce this in MP.

Here's the long 27T double kill I was talking about. It's the same server, by the way.

I wasn't claiming not to believe you or anything, when I watch this I'm like 'what, asleep at the wheel?  don't have radar contact?' ... but obviously the do!  Just ... ok I'll STFU about it now.

 

Seems like it isn't an issue with the missiles.  I wonder if the IR signature has been set too low of F-18s.

Another strange possibility would be if ECM was affecting IR missiles (because there's ECM against those as well, it exists in game and maybe there was a programming/configuration mishap).

You might be on to something there. I did notice that my EOS lock drops the instant I designate a target, but sadly I can't pinpoint what exact airplane it was. My bet is that ECM, for some strange reason, causes this. My guess is FA-18 but I can't tell for sure. However, from what I remember, I don't recall seeing any ECM on my HUD.
