Hello, I have Hp Zbook 17 G3 with an Aorus gigabyte 1070 box. when I launch the computer ,my H2D is at 2000mib/sec , when I launch any game, that speed goes to 500 mib/sec. 

FPS seems low for a 1070. I tried updating firmwares and drivers.. still same issue.

 

any idea what the culprit could be ?

You measure H2D bandwidth with an unused eGPU link to get it's peak throughput.

By measuring H2D while your game is running then can deduce how much bandwidth your game has used at that instant, eg: H2D-max - H2D-current = H2D-game.

eGPU Setup 1.35    •    eGPU Port Bandwidth Reference Table
