resolution recording creates (pink is a system process responsible for the recording). As you can see this wasn't really possible.
Therefore I made
I think it's obvious that frame rate on Mac is visibly lower than Windows. My first impression was same with Ubuntu, but after more testing it seem to be same as in Windows.
I apologise if for some it might not be something that matches definition of slow, but for me it is quite noticeable.
Without GPS, on OS X OpenCPN idles at 1%, however, panning and zooming causes approx. 70% CPU load (along 4/8 threads).
All application versions, charts
and settings were the same. Each VM had 2 cores and 2Gb of memory assigned. OS X at moment of testing had approx. 1.6GB of memory free (unused). You may notice some routes on OS X, during the test. I removed them later and performance haven't changed.
Having played more with mouse on my work machine, I must say OpenCPN seems to be optimised for mouse users. I am not really sure mouse is a device used often at sea.
