Major stutters, very noticeable while in PD chases.

What happened?

Many times while we are in PD chases, WE (BCSO) notice a large stutter while in the chase, and depending on the location, this can lead to a complete loss to the chase due to not knowing what direction the suspect went during the stutter, it appears at the suspect we are chasing is completely fine and doesn't have the stutter as they always manage to just vanish, but our entirety of PD units on the chase were affected.

Not sure if you are going to need log files, I have simply started asking people from BCSO to provide me clips of these instances, and will continue to provide as much detail as I can.

For what its worth, this issue was happening prior to the server migration to the US as well, so I don't believe that to have made an impact.

The big picture for me here isn't the fact that we lost the suspect, ain't nothing wrong with taking an L, but we are taking a loss by something that wasn't preventable by us, as well as it feels like this happens in almost every chase we get into.

I don't believe these to be normal "head issues" due to people having not the best computers or network.

Expected result

No stutter causing loss of suspect.

Reproduction steps

1. Get in a chase with a suspect
2. Suspect leads you on a chase for a while
3. Major stutter happens and suspect has poofed.

Importancy

Slight inconvenience

Aware of this, I enabled profiling yesterday.

Hit F8 -> profiler record 500, wait for it to finish profiler view, wait for it to open and find the download profile button and submit it here, should be a json file.

Do this when the performance is degraded, it will let me know what's going on. I assume some specific PD function, maybe group blips, has a memory leak.

@SupperRobin6394 do as it says.

Files are too big to upload here, so I've utilized dropbox. I'm not sure how helpful it will be, as I would be starting the profiler just after the major stutter happens, as I can really predict when they will happen, and I imagine you are wanting the profiler to catch it actually happen. - - - Actually, I assume I can just start the profiler with a longer timeframe before every chase. and then provide that, just that the files itself will be MUCH larger.

Ok. Based off of that, I've fixed a memory leak, which is nice.

You'll need to do it again, after the next restart given the server has ignored profiling mode completely.

Here is another one immediately after a huge stutter. JSON Here

@tricksta1 try get another one now, might've fixed with this last update

Immediately after one happened.

Nice trace.

Appears vehicle stancing is the main cause, that and some routine hud draw calls.

F1 -> Settings -> Performance Mode will essentially soft-fix this for now.
