Re: Rpi 3/2 hardware opengl and Vector charts

I recently bought an RPI 3. It took some time to get the GPS (NEO 6M) running via UART (mainly because the port designation is no longer ttyAMA0 but ttyS0. Making magnet/gyro/pressure/humidity/temp sensors the the i2c pins was easy (just follow open plotter instruction and the specifics for debian Jessie which you can google easily). Also I needed to install besides the cgps module also the pynmea2 module to make open plotter accept the feed. But now all runs stable and well.
Open CPN works fine. I also attached a 7" touchscreen and can now work either remotely via tablet or direct on screen without mouse and keyboard.

I have seen that some people say zooming is faster with raster but I don't know how much effort I should put into trying to gather the info to try to get my Pi 2/3 working with HW opengl acceleration. Could someone offer me an opinion?
I am trying yo work out what computer I should install on my new boat and I feel the Pi doesn't quite cut the mustard for Opencpn. It will be interesting to see what the Pi3 can do

Nasim, what are you using for the touch screen? The official rpi one? Is whatever you're using sunlight readable?
