(13-6-2018) Suspension behavior issue for all AMX-13 frame based vehicles

[Tantor57 10,319]

I'm openning this bug report to point out the fact that all AMX 13 frame based vehicles in the French tech tree suffer a very disturbing issue regarding their suspension behavior.

 

The issue is that their suspension is very, very, very, wobbly as if they were only equipped with bungie springs in place of it's simple torsion bar system coupled with schock absorbers.

 

That heavily cripples the vehicle while in motion because the slightest terrain deformation will make the vehicle wobble so much that it will slow it down terribly due to the suspension locking it self up causing the vehcicle to suddenly break or if you're unlucky, turn it upside down.,or when going down hill fast, once you start to go on flat terrain again, the vehicle will pitch forward and suddenly be blocked because the front of the vehicle is scrapping the floor. It also makes aiming after a full stop very painful since the frame will bounce up and down several times.

 

At last, i would like to point out that the Pz III frame based vehicles once suffered the very same "bug" as per having extremely wobbly suspension that caused exactly the same issue, and while it was less noticable on the move due to the Pz III not being near as mobile as AMX 13, when they performed a full stop the very same extreme bounce occured. They no longer suffer this issue due o it being fixed a while ago.

 

This issue is easily replicable in the game just by driving around with any vehicle based on an AMX 13 cahssis.

 

I will not provide any source regarding this issue because i beleive this issue to be on the coding side rather than hard datas.

Hey Tantor,

 

Could you at the very least provide some footage of an AMX-13 driving, or something similar? While it's hard to find hard data on suspensions, some reference material is appreciated.

Hello,

On this footage (around 1:00-1:30 on the video) you can at least see that the tank does notre wobble on stop.

I hope it helps!

OP updated with the clog and DxDiag.

As requested.

 

First video, go all the way to 0:50 till 1:00 you can see when the tank goes over and down the small hill, it remains pretty steady. Nothing like in the game. Note that the AMX 13 featured in the video is the SS11 variant. That's for now the only worthy video i managed to find regarding suspensions behavior.

I found a few videos of AMX 13's driving, stopping and firing without their gun rest.

 

 

While the tanks and their turrets wobble a little bit, it's a lot less than what happens in War Thunder.
