hello
following are my specifications
AMD sempron processor
gigabyte motherboard
2GB ram
1GB ATI RADEON graphic card
500 GB hard drive
and the problem is GTA 4 is not working on my computer
it is lagging a bit....
i use the 1st copy version of GTA 4 ..
so i urgently need help...

Your running a weak cpu things like this are going to happen.
Turn your settings down to where the game doesnt lag.
If it continues even on lowest settings well.....

List your gpu, 1gb ati isnt specific enough.

What OS are you on?

How many apps. do you have running in the back ground?

What sempron cpu do you have exactly?

What settings are you currently using?

-------------------------
More Advanced Micro Devices than Intel

Also what Gigabyte board? Far to vague on your specs.

A semperon isnt really gonna cut it unfortunately.

I actually built my present pc around the need to comfortably play GTA4 and I chose a quad core processor for that very reason.

The box actually staes the minimum is a 2.4ghz X2 processor and thats what I had a 6000+ at 3.4ghz and it just wasn't working (@1680x1050)
