I had this pulsing stutter in previous updates. But i found a workaround, which is setting navdata to "Sim Default". I didnt get a reply for my bug report though. They dont seem to care.
Otherwise agree. Terrible performance, even with "EFB Performance Mode", "Reduced Resolution Pack" and "No Cabin".
