Occasional severe stutter when getting close to the ground in a dive

[Sylosis]

Hi,

Might not be only Harrier related, but I'm flying the Harrier lately and this has happened on at least 3 occasions, one of which made me crash. If I dive for a gun run, it sometimes happened that I suffer from sudden extreme stutters that'll last maybe 1 second or 2, which is enough for possibly crashing. I can't attach a track because the only one I have is too big. It was at towards the end of a relatively long mission. I don't think I can edit/cut a track to keep just the relevant part, right?

Also, this has happened on both the Multi-Thread and single thread version of the open beta. Every time it was in the Persian Gulf map, during day time. Every time, it was a dive for a gun run, just as I want to pull up.

I don't know if the track will be easily watchable, since I did sped up time during my mission. From what I know, there is still that problem that tracks get "broken" whenever they are tracks from a mission that was accelerated.

I have a decent computer and usually don't experience stutters, even when close to the ground. I don't even think my game settings are maxed out.

Could it be you are trying to pull off the dive too hard at a high speed?

Try it at a moderate dive angle and keep the speed a little lower and see what happens. 
Remember to keep your rpm up so the gun works, sorry I can’t recall what the minimum rpm is.

Can confirm this has been a harrier bug for over a year,  any time I am close to the ground I sometimes get a massive freeze frame/stutter/lag/, between 1-5 sec's in length.

- the freeze usually occurs on the transition from high>low altitude flight or while flying down low. IE: going into land, starting an attack run, or just freeflight with rapid altitude changes close to the ground.

- it can happen multiple times in a row, for example, just now i had one 3s freeze then 4 secs of normal, then a 5s freeze then a few secs of normal, then another 2s freeze, then normal.

- It's a bit random but happens at least once every flight for me so it should be very reproducible.

- it doesn't seem to matter what is on the MPCD's tgp, flir, tv, etc.

- i use track ir and it seems to happen regardless of headpostion or camera direction, (I think its related to the direction the jet is pointing or its location/speed, not what the camera is looking at, but I'm just guessing based on how the bug seems to behave. )

- it happens with mirror reflections both on or off and pilot body on or off.

- the aircraft seems to keep flying in the background and will accept control inputs IE: if it freezes and then you give full right stick, when it unfreezes in 1-5 secs you will be mid roll, or if you were headed towards the ground and do nothing you will crash into the ground.

- if the plane crashes into the ground while the screen is frozen it seems to unfreeze the screen.

- it's been a bug for at least a year and was originally why i stopped flying the harrier, coming back to flying it now its still there.

- is present in both single thread and multi threaded versions of dcs.

- it happens in multiplayer, (not sure about single player as I don't play SP that much, but I can test SP if a dev requests it.)

- It its not present in any other module that i own including: viper, hornet, mudhen, apache, hip, fc3, warthog 2, blackshark 2&3,

- I've upgraded my pc in the last few months to a 7800x3d, with 64gb ram, from an old fx-8350, only the graphics card 980ti, and 1080P monitor is still the same between machines, including a fresh windows install. bug is present on both machines.

 

 

I Would really like to see some progress on this bug its probably going to be a hard one to find given how inconsistent it its, and it seems to strike at the worst possible times in critical phases of flight and often causes me to crash the aircraft.

im happy to help with finding the cause of this bug, if you need me to run more tests or run with debugging software on my machine, just let me know.
