Blast seems capped around to 8 Mbits

Hello,

I was testing youtube playback over blast. Vm's have W10, 4vCPU , 8GB of ram and a K140Q  Nvidia profile.

The bandwidth Blast uses is always around 8 Mbit,, it makes no difference if I play the video windowed or full screen.

Is this expected, I would imagine to see higher BW usage in full screen.

Moreover only edge is performing. Firefox and Chrome are terrible even in windows mode.
