P3D v4.5 huge performance drop with Chaseplane

[PapaCharlieKilo 1]

Dear fellow simmers,

I have just finished my new build (see signature).

Everything is working pretty well, though I might suffer from the mediocre performance some folks encounter with v4.5.
Anyway I am able to achieve 25-30 FPS in the 787's VC in heavy weather at LEBL with settings on the higher side, AS16, REX Skyforce and UT-live.
But as soon as I start ChasePlane my FPS drop to 3-5. This happens with both the new experimental update and the earlier non-experimental.

Has anyone else come across this problem and has eventually found a fix for it?

Thanks in advance,
Peter

Wow... support response with AT LEAST a comment or a "thanks we're looking into this" would be a minimum. Typical example of why payware should never use forum-based support model... Same issue here.

These are User-to-User forums, primary line of support is accessible on the OldProp website here:

Thanks for the information, mea culpa, but still... I have seen the devs step in, occasionally. You'd think that performance impact issues would prompt a response, no?
