Hi, I recently just installed IV and my graphics card is a Sapphire Radeon HD 4850 X2 2GB, processer is an AMD Phenom II X4 940.. Though i'm still lagging quite a bit. My friend said the possible reason is that GTAIV doesn't support 2 cores on the graphics card only 1. Is this the case? Or is this something I can fix? If you need more info let me know please.
P4 is ok but u need minimum Nvidia Getforce of 512MB video card and u have only of 128Mb so it might not work and one other think u need XP sp3 for that u have to download or buy CD of XP SP3 that will update ur system no need to for mat and all.
I could play GTA IV on a P4 socket 478 3.0GHz CPU with 1GB of PC2100 DDR RAM and a HIS HD4670 1GB AGP Video Card, oddly enough after upgrading to 2GB of PC3200 DDR RAM I now experience game freezes or lockups often, it was better with 1GB of RAM.

gta4 will not run on a 1.6GHz dual core pentium, even if it did it will run like a slideshow. Also, i assume that if you have a pentium dual core, you probably have integrated graphics, so i'm afraid it's a resounding 'no' :( my desktop has a 2.9GHz athlon X2 and a OC'd HD4670 and that only still reaches 20-30 outside (cpu bottleneck ofc).
A Pentium 4 is just too slow - the official min CPU is a core 2 duo
The PC version of GTA 4 has CPU power for breakfast - independent on clock speed, L2 cache or number of cores. The latter ones are very important, because without quad-core power GTA 4 is noticeably less enjoyable. For example: A Q6600 is about 52 percent faster than the dual-core E6600 when both CPUs are running at 2.4 GHz. If the clock speed is increased, the difference gets smaller, but is still huge and a QX6850 is 47 percent faster than an E6850. Dual-core processors have a serious disadvantage and only with 3.6 GHz an E8500 is able to beat the Q6600, but GTA 4 nevertheless suffers from frequent lags on dual-core systems - no matter if an AMD or Intel CPU is used. The Phenom X4 9950 easily passes the Q6600 and theoretically is on the same level as the Q6700 (not included in the benchmark).
hello i have a 3.0Ghz 800FSB veryiportaint 3GB ram & 512mb video you must have like this and windows xp pro with sp3 serivse pack and your video card must be update your video card is 128 is to low for it try 512
GTA 4 requires a really good CPU I have google it and found out that it is not much of a difference between 9600 GT and 9800 GT but by changing the cpu from dual core to quad core it produces much better results
