New HD3870 wont play COD4...

Bought a HD3870 (Diamond) and when I go to play COD4, it crawls. I never had this problem with my 1950xt. I was able to play a map once with no problems, but as soon as the map changed, crawled to a stop. I'm using the default "optimized" settings too. The same settings my 1950xt had don't work either.

I was able to run 3dMark06 with no problems at all, worked great. Going to pick up rainbow six vegas 2 tomorrow and hope that works but I'm wondering if I should return the card for a replacement or find out if there is another issue going here.

What cpu? It matters too.

Sorry, here's my specs:

CPU: C2D E6400
RAM: 4gb DDR2 5400
Motherboard: Gigabyte GA-P35-DS3L
PSU: Antec Earthwatts 500w

When i first installed the 3870 I used catalyst 8.2. Then updated to 8.3. Then went down to 7.12 (3870 release drivers). Now i'm using the omega drivers.

I haven't tried reinstalling the game so I'll give that a try.

oh really? is it a firmware/bios patch or just a driver patch?

Mav: nope, didn't work.

I have the same card, Ati hd 3870 Diamond and i'm not experiencing any issues with cod4 with the 8.3 catalyst drivers.i suggest you reinstall the game and patches.

No, have you tried other games?

Hopefully the reinstall will work as this one do0es seem strange, good luck, and get back to us

Oblivion is fine after patching it. Works great as well... Wonder what the hell is going on with COD4 :\

I have a hd3870x2 and when i first start COD2 itwill lock up system after i reboot all works fine, and it is the only time my computer locks up, i have not been able to find problum so i just restat system when i want to play COD2. Has anyone else had/have this happen to them??

I had the same problem. Download the latest DirectX iteration, and you'll be fine. I'm running a 3870 with CoD4 and it's running smooth as silk. Only a little choppiness with multiple helicopters in the air.

I install cat 8.4 and it stop bsod when i start cod and framerate is better all is good

Nope they don't suck. I play COD 4 online at complete maximum on 1920 by 1200 at 40+ fps. Tiz two 3870's in crossfire , but bout same as 3870x2.

jcgross how are your temps on gpu? is it getting hot?. Also i don't quite get what you are saying about 1-1/2 game? i finally fixed my problem by installing gpu drivers,dircetx, .NETframeworks tnen in safe mode cleaned old drivers then reinstall all works good now but i don't know what really cause it

HI All,
I bought 2 new pc identical HW both with Saphire 3870x2! So One of the 3870x2 cards was buggy from the start and i went back to get it replaced 7 times (it was making whistle noises but worked besides that). After the 7th time is changed brands to PowerColor 3870x2 thats when i got the direcX error on COD4. I swapped the video cards in the 2 pc and the error followed the Power Color card!!!! and i took that MOFO right back to the shop im requesting a ASUS brand now see how it goes.

SO I TELL YOU ALL RIGHT NOW ITS THE ACTUAL VIDEO CARD...... NOT YOUR OTHER HW OR SW TAKE THAT SUCKER BACK AND EXCHANGE IT.

I love ATI but after this exp im worried about my next replacement. I was lucky i bought 2 identical systems otherwise i would of asumed that this is normal. I bet alot of people think noisy & buggy cards are normal but after this if its not silent and works %100 im not keeping it we pay enough money for it to demand %100.

Here is a good one after all that happen is this thread http://www.tomshardware.com/forum/ [...] s-problems my card after aprox three weeks my new card died, it has been 2 1\2 weeks sence i rma it the factory ( diamond ) is less than 100 miles away from me
