After adjusting the suspension to lean forward, the BMD-4M2 always experiences an unexplained jitter, as shown in the video. This causes the gun sight to shake along with it, making the gun barrel constantly bounce up and down and rendering aiming impossible. It severely impacts gameplay.
I am not certain if other BMD-4 variants have a similar issue, but I hope your team can investigate and have it promptly addressed.
You can bug report it here (just search a bit first so that you don’t report something that is already reported and known about): (Gaijin.net // Issues)
A guide on how to report bugs can be found here: ([Navigation] Technical Knowledge Base | War Thunder Wiki)
The bug report site doesn’t seem to support uploading videos, and using images alone isn’t enough to describe the issue clearly.
You can upload the video to another site (like youtube) and link to it in the bug report.
A screenshot is still required not because of the image but it puts a tag in the logs/code so that the developers know where in the code/logs to start looking for the issue (which is why the screenshot needs to be taken with the in-game functionality and at (or near) the moment the bug appears). Without the screenshot there would be tens of thousands of lines of logs/code to go through and try to find the issue, with the screenshot tag it cuts it down to a couple of hundred lines instead.
