I have the same problem. Using UK oesnc vector charts I cant get get any sort of reasonable performance. When no charts are loaded I am able to pan and zoom the base map at high speed, but when loaded it can take 10 seconds to move the chats. Very frustrating. This is with a 3b+ pi and open plotter 2. I tried a raspberry pi 4 which also has poor performance.
I've had better luck using qtvlm with visit my harbour vector charts in terms of performance, however i did find it would crash fairly regularly. In the end i'm using a windows laptop hidden away in the chart table connected to the monitor orignally installed for the Pi. What is fairly surprising it draws around the same amount of current (600mA) as the the Pi 3b+.
