Nan mais c'est typique d'une puce nvidia dans une merde machine acer : un GPU avec un gros potentiel mais ultra bridé par l'utilisation de DDR3 au lieu de GDDR5 qui réduit la bande passante par 2.
L'article de AnandTech est clair la dessus :
"With all that information now on the table, it's reasonable to say the GT 640M is definitely a powerful GPU and certainly a step forward from the Fermi-based GT 540M. At 768p, even a DDR3-equipped 640M is undoubtedly going to provide the excellent gaming experience that NVIDIA promises, but anywhere beyond that is still going to require more memory bandwidth, full stop. There's only so much one can do with the die before having to make that concession, and I feel like the 640M needs GDDR5 to really shine."
Donc Laptop Acer "haut de gamme" = économie de bout de chandelle et dalle faible résolution
