Battlefield 3 Laggy ?

Just downloaded reloaded version from games section and tried to play it
It ran fine however it seems laggy on sp, like when I turn around it doesn’t feel smooth.
Installed latest graphic card drivers, direct x and tried to play it on low video settings but still same issue.
My specs are i7 Q720 @ 1.60GHz, 4GB RAM DDR3 & GeForce GTS 360M
Any ideas please ?
Thanks in advance
Answer #1
Turn the graphic settings down some.
Also try disable HT in the bios.
Answer #2
What you mean by turning graphics settings down ?
I had already tried playing in low settings =/
Can I ask how would disabling Hyper Threading in bios help please ?
Thanks in advance
Answer #3
Go into the bios. and look through it for intel hyper threading then change the option from enabled to disabled.
There should be a patch out to sort out the HT issues at some point.
Answer #4
GeForce GTS 360M
Core i7, is that your Laptop? I heard some people could play this game on Laptop but I don’t know if they got powerful Laptop or not.
Answer #5
Yes I got a Toshiba Qosmio X505
Edit:
Would like to add that I’m playing it in single player and hard disk is almost empty due to formatting last week
