Anyway, I just bought an ATI 4850 after selling my 8800GT to a friend. It installed fine, but I get a weird video resolution problem when I try to set the video resolution in COD4. I have a 22" widescreen that runs 1680x1050, but when I try to set COD4 to this resolution the computer freaks out and goes into some kind of video testing mode. It goes black and then to vista desktop, then repeats about 8 times. After all this, it settles in on a resolution of 1440x900. After exiting the game, my vista resolution is screwed up too and I can't change it unless I reboot. Quite annoying.
Any suggestions? I searched some, but I have found no similar problems yet.
I have an Asus P5E-V HDMI with 4 GB of Gskill 1066 running an E7200 mildly oc to 3200 with 600w ultra x2 ps.
I have updated the ATI drivers with the hotfix, but not fully updated the COD4. I had a problem on my other system trying to go to 1.7 so I did not do it on this system yet. I guess I will give it a shot and let you know.
Updated Call of Duty fully and still having this problem. It is really annoying. Computer has to be rebooted after exiting a game I have to play in low res! ARRGGGHHHHH Makes me want to go back to an 8800gt.
COD4 is about the only game I am playing right now, I don't even have anything else loaded to test this problem with. I guess I should load another game and see if any other work. That might tell me if I have a problem with directx or something.
I would be exceedingly careful about saying anything remotely negative about the 4850. This forum seems to be rife with ATI zealots that will crucify you at a moments notice. I you are having problems with that card, you are apparently part of the same microscopic minority that I belong to. I feel for you and would not have you suffer the same fate as me.
I play COD 4 with a 4850 card and have tried 1680 resolution to see if i get same problem as OP but it runs just as well as when i play at 1920 resolution. How can i help you if no one else who even has the card has the problem?
I am wondering if it has something to do with unloading 8800gt drivers and loading 4850 drivers. I went through it in proper order: uninstalled 8800 drivers, uninstalled ntune, installed 4850 drivers, installed hotfix.
No luck yet. Just hoping someone has come across something similar. I would just reload vista and try again, but I have loaded this box 3 or 4 times in the last month just playing with different OS and I really dont want to do it again!
Ok, Mousemonkey made me laugh, i'll admit it.
May be something stupid but Power supplies do weird things. Are your sure your Psu is up to the task? Unlikely i know but iv seen weird things.
ATI doesn't seem to like COD4. There is another guy on this forum with a new 48xx who's frames are capped at 20 fps. That sucks.
strange, i had 8800GT, n upgraded it to ATI 4850, n changed my resloution to 1680x1050. and i've being playing the game for a week or two (online).
i didnt cross the problem you having. did u install the driver's properly. like uninstalled the nvidia one, used driver cleaner, then installed the new drivers of ati (install the hotfix only, dont bother bout the ones that came with cd).
n ya, both xp and vista ran fine (since i have multi-os). but i have vista problem with pb n it keeps kicking me out. so i use xp to play cod4.
