GTS 250 Lag

[Shappo]

Hey guy's.

I just build myself a new computer, it consists of:
i5 750
MSI P55 GD65
G.Skill Ripjaws 4GB *2x2*
XFX GTS 250
Coolermaster 550w
320 Seagate Barracuda HD
LiteOn DVD Burner
TP-Link 54 mpbs wireless card


Running Windows XP professional service pack 3 (32 bit)



Anyhow, do a clean install of windows.
Install the drivers for each hardware. (everything is installed)

Install a game called 'postal 2' to test my graphics card out.

Here's the problem.
When I play multiplayer online I get a fair bit of lag. (Never had this on my dell laptop running vista)

But the normal gameplay (not multiplayer) is fine..

Could you guy's suggest the problem?

I suspect the wireless card is more likely to be causing lag whilst in multiplayer than the graphic card.

Multiplayer games are extremely sensitive to latency. If the single player version of the game runs smooth, and multiplayer does not, you're almost guaranteed to be having a latency issue.

Wireless internet is NOT very good for gaming purposes. Between potential signal loss, interference, and lower bandwidth you'll find more latency issues.

No problem. Good luck!
