I received Civilization IV for Christmas (I like to stay a generation behind on a lot of games – cheaper, usually bug-free, and I don’t need a new computer to run them – and yes, I’ve seen the relevant xkcd). However, the “bug-free” part isn’t holding up this time.
[This](http://www.sirblah.com/misc/civ-screenshot1.JPG) is how the game is supposed to look. However, every minute or so the game blurs out, lasting 30 second to a minute. [This](http://www.sirblah.com/misc/civ-screenshot2.jpg) is what it looks like when it happens, and
[here](http://www.sirblah.com/misc/civ-screenshot2-closeup.jpg) is a closeup of the lettering of that second screenshot.
Here are the particulars:
I’m running it on an HP Compaq 6910p laptop with WinXP Pro
128 MB of DDR3 ram
Here’s the info center report:

So far, I’ve tried the basics – rebooting, disabling everything that wasn’t system-critical, etc. I’ve updated the graphics driver to the latest version, but no luck.
However, you’ll note that of the above-linked pictures, the first one is an actual screenshot while the second two are photographs of the screen. When I took a screenshot during the blurring and pasted it into Paint, it came up perfectly clear – an indication that this is something on the display itself, correct?
So…any ideas, anyone?

The display or the card, yes. In fact, since it only happens while playing a 3D game, I’d think it more likely to be the latter. Does the start menu get blurry? It’s hard to tell from your included pictures.
In fact, would you mind taking a picture of the not blurred version with a camera liike the others, so we are comparing like with like?

I’ve played that game for years and never seen that sort of screen. However, I do note that you have very little RAM- you state you have 128 MB with 512 MB being minimum and 1 GB recommended.
I can’t see what size Video card you have.
Possibly the computer you are using isn’t really up to scratch?

Your first problem is that by that date you should have at least 3 cities and be well on your way to inventing gunpowder! (only kidding)
Something is amiss in your stats here, you actually have 2GB of RAM, not 128MB (you can’t even get 128MB sticks of DDR3 RAM). Chances are your gfx card has 128MB RAM and you are confusing this with the system RAM.
Your computer is fine to run this game so something else must be causing it to trip up. Is there any reason you are running the game in a window rather than full screen? The first thing I would try is to run fullscreen so the game has complete control of the display (as far as it can) and then try switching in the in-game options between different resolutions and refresh rates. I’m guessing that this effect is never observed outside this game?

Yes – it can happen from any screen in the game. And if I immediately exit the game when it starts happening, the blurriness continues at my desktop or any other program until the problem runs its course a minute later (it doesn’t come back once I’ve exited the game, however).

[Sure thing](http://www.sirblah.com/misc/civ-screenshot1-photo.JPG).

Quite correct – my mistake. The laptop itself has two gigs of ram – 128 is on the card.

When I first loaded the game, it was in full-screen mode. I switched it while troubleshooting and never changed it back. I’ve tried changing the resolution and turning off various in-game graphics option, but no luck.
Appreciate the suggestions so far!

I remember this game had some serious issues with some specific graphics cards when released. Try finding patches for the game and update your video card drivers.

Can you hook up an external monitor to your laptop to see if it’s blurry too? That would tell you… well I don’t know what it would tell you. Does it happen immediately even if you start with a cold laptop, or does it need to heat up before the problem appears?

Please run DXDIAG, Save All Info, and post dxdiag.txt here (first delete everything after the Sound Devices section so it will fit).

I did try hooking up an external monitor, but for some reason it wouldn’t respond (I just chalked it up to the fact that the monitor I tried is a huge POS (which is why it’s stuck in a closet in the first place). No difference between cold and hot.

If the problem didn’t go away, it would tell you it isn’t the laptop’s screen, but the card. Whether that was caused by bad software or not would still need to be determined.

Go ahead and go to the appropriate Tabs in DXdiag and run those. Those are the 3D parts of the graphics, so that’s what the game is using.
They’ll probably be fine if you’ve had no problems with any other game, but it’s still worth a check.

Did you indeed update your video driver? That one is from 2008, so check with HP (ATI don’t directly supply drivers for OEMs).
Also, any particular reason for not going to SP3 on XP? Not that I think it has anything to do with this issue, just wondered.

Just tried that, and for awhile there I thought it did the trick. It took about five minutes before the same problem cropped up. Damn.

This is a work-issued laptop – I have free reign to make a lot of changes, but updating service packs is something that needs “approval”, and has to be done to all the laptops in our group.

With the external monitor, you’ll likely have to hit a key (fn7, IIRC) to switch between LCD only, LCD + external, and external only.

What resolution and refresh rate are set in the game? What is your LCD’s native mode?
Try the latest DirectX 9.0c installer from Microsoft (dxwebsetup.exe), save it to a local directory, and then run it.

The game should automatically detect resolutions the monitor can handle (there is no way to change the refresh rate in the game). It does so with my laptop monitor, and if I hook up an external monitor, it will only allow the resolutions that monitor can handle\*.
I have definitely never seen such blurring in my games, and by seeing that his desktop is also blurred makes me wonder (if I didn’t know better) that he moved the camera when he took the photo (especially since the screen capture is not blurred).
\*ETA—however, before I do so I have to use a “neutral” resolution such as 1024x768

Do you get the problem in any other 3D games? How about when playing movies?
