Hello guys, does my video card support bf3 multiplayer ?

Nobody knows?:(

According to this, no

Don't even think about playing it well at all. The G405 is essentially the performance of an 8400GT.

You could probably play a bit in the menus but not in the 60+ fps ;-)

Laptops are not made for gaming /facepalm
Buy a Desktop if you want to play Games! Laptops are a waste of money when it comes to performance, you get 500% more Performance for your money with a desktop!

I got Intel E5200 Dual Core @ 3,3 GHz, Radeon HD4850 and 6 GB of RAM, I can play it on low/medium. My card can be compared to GeForce 9800GTX / GTS 260, from what I remember. Also, playing it on 4 GB RAM is problematic after some time.
