solved Multiplayer - significant drop in frame rates part way through a mission

[Mr_sukebe]

As per the title, I was out in MP yesterday with an OK frame rate in VR.

Part way through the mission and had a frame rate drop from in the 30s to 5fps.

Log attached.  The issue appears to be sometime in this time block:

============================================================

I'll go disable Tacview as a starting point and try again shortly.

Any other ideas?

Looks like it could have been Tacview.

Interestingly, I'd already disabled Tacview in the "special" menu within DCS.  Seems that disabling wasn't enough.  I completely deleted it, including the hooks, folders etc.  That seems to have worked as I certainly didn't have the same frame drop issue.
