Refueling from S-3 Viking is very laggy

[LePaul]

Running MT version on 4YA server last night.

First time refueling from the S-3 in the F-14 and I expected a challenge and my FPS (VR) has been great.

But for some reason, as I would approach the S-3, I was getting some jumpy video/lagging suddenly.  

Is the S-3 optimized / working OK?  Anyone else experiencing any issues?
