BaseCamp 4.8.11 + macOS Big Sur 11.1 is still slow?!

Yes, I also see this. BaseCamp even with the default global map (which has almost no detail at all) is painfully slow. Scrolling around, zooming, or doing pretty much anything goes at a snail's pace. It's maybe one frame per second, max? I have the latest MacBook Pro with an M1 chip, which is one of the fastest macs out there.

I have the same problem, with Big Sur 11.1 simply impossible to use Base Camp, any suggestions? or does anyone know when Garmin intends fixing the problem?

OMG...this is making me nuts! Sooooo slow even after the latest BC update. What's going on?

20 days later... still no response from Garmin

More than 6 months later... Pffff.....Haven't heard from Garmin... There is version 4.8.12!
Before the update I did a test with a route of less than 200 kilometers: 

Regenerate time: 128 seconds!

In 4.8.12 >>>>> 5 seconds!! Wel done Garmin!

The (re)generation of a route is in fact much faster with version 4.8.12. But navigating and moving within the map is still extremely slow under MacOS Big Sur. You can help yourself as follows:
- Menu View > Show 3D maps only (translated from the german version)
- In the map navigation control, double-click on the middle crosshair of the compass. The view will then be oriented vertically from above.
- Click on the north arrow at the top left of the map to reorient the map to the north.
- You are then in a kind of 2D view, but you have the speed of the 3D view.
- The fonts and icons on the map are a bit blurred, but I can live with that.

Great tip - thanks! I haven't noticed any increased blurriness.
