Nasty problem with XSB 64 2b and Skymaxx Pro - Mac

[gmiller51]

I've been told by a friend in my VA, that I might be alone in this issue, but here goes....

 

2012 iMac 27, loaded- OSX ver. 10.8.4,Processor: 3.4 Ghz Intel Core i7',Ram: 32 GB 1600 Mhz DDR3,Graphics:  NVIDIA GeForce GTX 680MX 2048 MB

Xplane 10.25

XSB 64 latest update

Rammzees B777

and just bought and installed Skymaxx Pro.

 

Issue is flying on VATSIM with above.  When preparing to take off all is working, beautiful skies, squawkbox is connected.

 

Then there is an issue that sometimes exists and sometimes not.  And when it does exist it's MOSTLY in heavy Vatsim voice (as in a FNO).

 

Starts out as an audiable "screech", like tires on landing.  When it's bad, it continues and the frame rate goes from 25-30 to 2.  Everything is pausing including voice with ATC.

 

Sometimes switching from internal cockpit to external stops it, and framerate is normal!, but that doesn't work when it's constant.

 

Cameron at Skymaxx seems to think it's the SB codec for the new 64bit version.  But before I installed Skymaxx, SB 64 was fine.

 

If anyone has a clue about this issue, please contribute.

 

I just want joyous Vatsim experiences with awesome A/C and environments.

 

Thanks,
