Hello man :
CrispyChips :
The 1GB of Vram will limit your textures to medium at most,which is good considering your graphics card is rather weak by todays standards aswell.
I use a GTX 460n and play WarThunder maxed out.
...And?
Warthunder is not BF4,its not even the same engine. Its waaaay less demanding than BF4.
Plus the GTX 460 is FAR stronger than the HD6670.
Apples vs. Oranges,man.
