P3Dv4.1 | Strange freeze / Uncontrollable aircraft

[Sas330 1]

Hello Forum!

Recently Ive encountered strange, and rather annoying bugs with the PMDG 777-300ER (V4-version)...
I was landing into Heathrow, when the plane suddenly became completely uncontrollable. The yoke input lagged.

I was too high, but had space to correct that manually.

Ive included a recording of it here: 

Thanks for any help!

Looks like your run of the mill overtaxing of computer resources to me, not a "bug". What's your hardware and settings?

This is a bug and has been reported elsewhere including the LM official forum. It seems to be related to some conflict between specific 3rd party aircraft (PMDG and RealAir seem to be the most commonly associated) and P3d4. The symptoms vary from slight fps drops when using the mouse to severe stutters to complete loss of joystick control. Andreh is correct in one sense. The symptoms are exacerbated when the hardware is stressed.
