BNO lag when gps on is this normal?

Is this normal behavior?

when gps is connected over bluetooth or usb i have lag like in video below.

without gps connected in simulation its lag free. see video below.

Can someone coform is this normal?

Check your gps output, i had same. To many gps data. Only output gga and vtg.
Adn when usimh simplertk board remove infomsg from output.

Look with a serial.monitor that it only spits out a gga and vtg message.
