Since the latest firmware and TopoActive map updates, my Edge 540 has become incredibly sluggish. It feels like a severe CPU bottleneck.
Aside from standard navigation and map redrawing delays, sensor alerts are heavily queued and delayed.
Example: On a recent MTB ride with a few jumps close together, the Edge 540 gave no real-time feedback. Only after the trail smoothed out—30+ seconds later—did the device start popping up jump notifications one after another for features I had cleared long ago.
It seems the processor is so overwhelmed trying to render the heavy new map graphics that real-time sensor metrics (accelerometer data for MTB Dynamics) are getting deprioritized in the processing queue.
Is anyone else experiencing this UI/sensor backlog?
