Left 4 Dead 2 - Frame Rate Issues?

[jcb33]

Hey all,

My PC is a bit old now (Coming up 4 years) with the following specs:

AMD X2 939 2.4Ghz
2GB DDR 1
ATI X1950XTX 512MB

Now I can run Left 4 Dead 1 maxed out with no probles, and the system specs are the same for L4D2 however even with medium settings I am getting average frame rates of 15 - 25, with extreme lag in areas like "The Park".

Anyone know what could be causing this? Thinking of getting an ATI X4850, would this stop the problem?

Thanks,
Jcb33.

I am updating my drivers now, however I will fully admit that I am not sure how to overclock a socket 939 setup, as I have not overclocked since Socket A. I also only have a stock cooler and already get around 50c average temps at stock.

Also I am sensing a no to upgrading to the 4850, as it looks like its not going to make that much difference?

Thanks again,
Jcb33.

CSS and TF2 which also use the Source engine need a decent CPU. Best to get a good cooler and read up on how to OC with your motherboard

Can run CSS, TF2, HL2, Portal, L4D etc maxed out no problems, just L4D2, that having been said I just tried disabling multi core rendering and everything seems to have speeded up
