Hello,
The most disappointing , is it seems we are getting better performances
with a lower quality Graphic Card ( talking about Nvidia family ).
This won't encourage to buy a better one.
But more technical explanations , architecture of the computer, operating

That talk could end with an open question, and no answer :(
