I just upgraded my computer from Windows 7 to Windows 8 Pro this morning and the game seems broken. First it wouldn't launch, then I can't connect to server after I've joined a lobby (after the game has begun, the loading takes extremely long and eventually I get a message that says 'Unable to Connect to Server'). I can quite safely say it has nothing to do with my internet, because this happened all day and my internet is working fine. Please help me out!
Thanks in advance!
I can safely say it's not an issue of Win8 either I did a "clean" upgrade from 7 to 8 too and while Steam wasn't cooperating very well initially, the biggest problems seem to be solved by now.
If you haven't re-installed CoD since you upgraded I'd do the "verify integrity of game cache" trick, starting with single-player, then multiplayer and zombie mode last. Start each mode once, in that order, and the game should be working correctly again.
If it doesn't your upgrade installation may be borked or doesn't work too well with some piece of hardware you're using.
Thanks for the tip. I didn't perform a 'clean' upgrade because I couldn't be bothered to install tonnes of programs on my computer. I managed to get into a private match and found the game to be extremely laggy. I think it has something to do with my graphic card not working properly, because when I try to check my graphic card setting, a message pops up telling me my GPU control interface stops working.
You gotta check if it's the card unable to handle the game, or if the card itself is damaged. Run PC Diagnostics (how to do it will vary depending on your computer, look online).
It will list the errors it has. Personally, my game crashed after about 20 minutes of playing, and it just so happens it was my memory that was damaged.
Yea, my laptop has a dual GPU, the more powerful GPU has now stopped working. I tried to find the correct driver everywhere on the internet but to no avail.
Also make sure your laptop is setup to use your graphics card rather than integrated when running the game. I've seen lots of people have issues with their laptop defaulting to the integrated for whatever reason. This can be changed in the control panel for nvidia and catalyst control center for ATI.
