Vista - Call of Duty 4 on Vista x64 help!

I just brought a brand new desktop. Gateway GT5692 4G DDR2, X64 Home Premium, ATI Radeon HD3200, with AMD Phenom 8450. I install the COD4 and the game play is so choppy! My friend has this game running on an older XP pc and his is running great....What could be the problem? Anyone please help....cause I feel like an idiot buying this desktop for almost 600 and can't play Call of Duty 4.

The HD3200 is an intergrated graphics card and as a general rule integrated graphics aren't great for gaming but what i've heard of the hd3200 it should be able to handle COD4. Try lowering the resolution in the game and turning down detail settings to see if that makes any difference.

Also check that you have the latest catalyst driver (8.8?) for the graphics card and you have patched COD4 to the latest version. (1.7 i think)

Thanks for replying. I did what you suggested and amazingly the choppy-ness goes away quite a bit. But there still some choppyness here and there. Is there any way I can play this game with better performances? Such as changing my video card or anything at all whatsoever? Thanks.

Your motherboard does allow for an extra graphics card i believe. It will be a PCI-express 16x slot I think. You can either buy another card and disable the onboard graphics or you can buy a ATI CrossfireX capable card and have the two running together for improved performance. The only thing I would bear in mind is that you have a 300W PSU and you may need more power for certain cards.

A video card would go a long way instead of onboard graphics. I think eggyuk made a typo? The sentence should read:

Yep was a typo. Thanks for pointing it out

Aaaa ic heh. So if i decide to buy another card and disable the one I currently have. Which of the video card on the market would you suggest that has a decent price? I don't really want to shell out another 200 just for a video card. Maybe 80-150?

I would go for an ATI card as you have an AMD/ATI chipset and it leaves the possibility of CrossfireX still open. I think the HD3870 like this: Newegg.com - SAPPHIRE 100225L Radeon HD 3870 512MB 256-bit GDDR4 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards $110 after rebate is pretty good or if you want to spend a bit more then the HD4850: Newegg.com - SAPPHIRE 100245L Radeon HD 4850 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Desktop Graphics / Video Cards.

But that's just me. I'm sure there are loads of threads on here with debates about the best cards.

i had this issue when i first ran cod4 on vista even tho i had a 8800gts. What i did was to install the latest directx update from microsoft. may not do anything for you but its worth a try.
