Offline lag

[varrasbelve]

Ok so, I downloaded Left 4 Dead off a torrent site and it works great except for the horrible lag I get.

I don't know what the issue is, me not being great at computers, but this is what my computer has:

Processor: Intel Core 2 Duo CPU E4400 2GHz
RAM: 2038 MB
System type: 32-bit Operating system
* ATI Radeon X1300 Pro 256MB
* ATI Radeon X1300 128MB
* Integrated Intel® Graphics Media Accelerator 3000

I have no idea what any of it contributed to the smoothness, but does anyone have any tips on how I can make it run better?

upgrade your graphics cards. Theyre smooth as a rocky slice of shit.
