Engine induced force kicks shaking

Recommended Posts

Whenever I'm revving up for takeoff the A/C shakes violently at certain moments. While testing for the infamous afterburner bug I noticed camera kicks. At that time I thought it's just a camera glitch, but it seems there's more to it after all.

If not for the in-flight occurrences I'd suspect a glitch in tire contact modeling but the spotlight is on the engines right now.

not map-specific

 

I'm going to post a track sometime later.

Here's the video and associated track file. MTOW 80%

Same instance but external view. It seems that it's the G camera setting is overreacting. No such movements occur on the airframe.

 

One last video and track - G effects on camera disabled (head bobbing disabled). Note that even with the setting disabled there are instances the pilot is "shaken in the cockpit."

EDIT FINAL:

Yeah, the case seems to be clear - here's what happens at engine RPM variations:

1. The in-game airframe actually jitters in a way impossible in real life.

2. Due to the huge accelerations the camera algorithm goes haywire.

Here's a magnified view:
