Here is systems specs

It's my little brothers computer and he plays games on 1280x1080
Every single game runs on 1280x1080
Even Crysis, Modern Warefare 2 at ultra high settings
But Assassins creed is not running well
It's lagging
do you guys have any ideas?
He is dying to play the game

try to lowering your resolution and turn off that "vertical sync" setting...
If that not help then try to re-install the game and see if your problem still exist...

Lower the settings or resolution. That card is ok for that resolution but not particularly good, especially if it is the DDR2 version.

Assasins creed really is a very badly coded game which results in quite frankly stupidly high hardware needed to play it any sense. Im afraid your brothers machine just isnt up to playing it properly.
As said try droping the resolution and turning off V-sync. Also make sure all settings in the drivers (Control Panel) are set for performance and that all AA AF etc is turned off. It wont be pretty but it may just let him paly it.
Aside from that Overclocking the CPU is an option, depending on your motherboard you could try increasing the Ram as 3 GB in recomended. Overclocking the Graphics card may or may not help.
Its getting to the stage where it seems a lot of bother for just one title but may benefit him in the long run.
These are the specs for the game.

As you obviously know from reading the back of the box you are short on Ram for a start and your CPU just about makes it in.
