Game runs slow on my PC. What else can I do?

[Mercenary42]

I did the following steps to try to speed up the game, but it is still running slow.

My initial configuration.

Dell Inspiron 5150
Windows XP SP2
3.0 GHrz processor
512 MB RAM
32 MB 3D graphics card – GeForce FX Go5200
DirectX 10
40GB 10GB free disk space
Broadband Connection - FIOS
Wireless card 11MB

My computer generally ran slow so I did the following….

Ran Quick Clean from McAfee (A good thing for all computers)
Ran Disk Defragmenter from Windows

I made the following hardware changes to my PC

2 GB RAM
64 MB 3D graphics card – ATI Radeon 9000
Broadband Connection - FIOS
Connect to the Hub 400MB


My computer is lighting fast with other apps, web browsing and so on, but I still am running slowly on POTC. Now if no other character is near my character, then I can run fine with a bit of a lag, once every 5 five seconds for 1 sec, but once two or more character are close by, I slow to a crawl.

My IMB Think Pad T61, running on the same hub lags on once every 10 to 20 seconds and the lag time is ½ second at worst.

Any ideas?
