Running a patch which works beautifully on both an iMac and a MacBookPro (2011).
On my new rMBP, it runs very very slowwwwly. I isolated and tested, and it appears that the jit.desktop object causes the system to have serious issues with framerate. If I remove it, the patch flies/screams... etc... it's amazingly fast and responsive.
Is there a known problem using jit.desktop with the new rMBP ?
