Odd artifact when in region view

12 posts in this topic Last Reply

I am having a weird issue when in Region view. All large cities are showing an odd band across the bottom border of the city. As you can see in this image, the band only shows on large city tiles, not the medium cities (or the small cities if I had any in this region).

I am playing SimCity 4 Deluxe digital version from GOG Games. My PC is a custom built running Windows 7 Home Premium 64bit. My Graphics card is an NVIDIA GeForce GT 610. My current startup options for SimCity are: "C:\GOG Games\SimCity 4 Deluxe Edition\Apps\SimCity 4.exe" -CPUCount:4 -CustomResolution:enabled -r1600x1200x32 -Intro:off -f -CPUPriority:high

Can anyone suggest possible reasons for the bands and how I might get rid of them? They are only in the region view, not in city view so it's more irksome than critical, but I'd still like to know what is causing it.

Thanks!

It's a bug due to using higher resolution than Maxis ever dreamed of peeps having. Once you go above 1199 vertical it does that. It is only a graphical anomaly, but quite annoying. The only known solution is to drop down the screen size, open each city tile, re-save, and then exit. That'll fix up the thumbnail which the region view uses.

  • Ah. Thanks. It IS annoying, but not enough to make me drop the resolution, which works perfectly for my screen size.

    Welcome to the forums. *:)

    Although it's not related to the region view issue as caused by an excess screen resolution, I just thought I'd mention about the "CPUcount" command...

    I notice from your startup line you've set your processor to use 4 cores. In terms of helping with the game's stability on modern multi-core processors, it's highly recommended to limit this to a single core by using: -CPUcount:1

    I'm not too sure on the exact technicalities. But this being a 2003 era game when the old Pentium processors were around, it basically doesn't know how to take advantage of today's technology. Therefore without restricting to a single core, SC4 can be prone to increased instabilities (crashes to desktop).

    I know this and I always did. However, I was playing with one of the launchers and noticed the setting so I decided to play with it and see what happens. So far, it's not crashing and seems to be running a tad faster. I'll be watching for CTDs and if they get too frequent I'll dial it back.

    They'll happen as soon as you've grown some buildings and then you change the zoom level (perhaps while the clock running; I can't recall exactly). The game's developer thread will be updating some data at the same time the display thread is trying to redraw the scene, and because the two threads do not synchronize data access properly for true multi-core multi-threading, a concurrent access exception will be raised, and you will crash to desktop, losing all unsaved work (and as much time as your system needs to reload the game and city).

    So, go ahead and paint some towns with roads, zones etc using multiple cores, but change that setting before the session in which you plan to start the clock running on development in any of them.

    Thanks for the heads up. I will definitely remember to do that then.

    sorry to just barge in, but can you please tell me how to set this cpu count thing? I think this is why I having so many crashes all of a sudden on my new laptop. Thank you :)

    Just to clarify along with the resource @CorinaMarie linked above, the parameters including CPUcount work when added to the "Target" field of the game's shortcut. First of all it references the game's executable file. Then after the closing quote and a space, any will be sent as instructions upon clicking the shortcut to start SC4.

    Like so:

    SC4 Target Shortcut CPUcount.png


    As per the examples, each command can be added separated by a space and a hyphen.

    For instance my full "Target" field contains:

    "C:\Program Files (x86)\Maxis\SimCity 4 Deluxe\Apps\SimCity 4.exe" -CustomResolution:enabled -r1600x900x32 -f -intro:off -CPUcount:1


    Describing from left to right as highlighted (the order doesn't matter):

    1. Enables a custom resolution to be set.
    2. Defines the width, height and colour depth of my custom resolution.
    3. Runs the game in full screen mode.
    4. Disables the game's intro loading sequence.
    5. Forces a single core to be used at all times.

        Hello all, I have found some strange colors and lines in my game, anyone know the cause... thanks

        Greetings everyone! Although largely unnoticed, I withdrew from the community upon the passing of my little brother in March of '16. Just prior, I discovered a secret of the software installation that could potentially benefit any style player and even help ensure the game's continued viability. However, that knowledge might have been disclosed or perhaps even documented since then. So, I must ascertain if there is any demand for the following procedure, confirmed working on Windows 7 through the recent release of Windows 10 requiring minimal freeware and no special skills:

        Aside from SC4 deluxe, I also play other games, including Starcraft 2.  Recently, due to Blizzard's changing the system requirements for that game with an update, I had to upgrade my video card.  Since then, SC4 has the worst lag issues I've ever had.  I have also had more CTD issues when dragging networks, or bulldozing.  A good friend recommended Cities In Motion 2 to me and I have started playing that.  Since transport networks have always been my favorite part of the game, I find myself getting far more enjoyment playing CIM.  I am seriously considering dropping SimCity 4.  As I continue to keep my machine up to date I have to consider that a game that was created for Windows XP may not be feasible on my machine.  Before anyone asks, I do run the game in compatability mode.  That being said, I want to let you all know that I appreciate all the great custom content available here and at other sites.  I also greatly appreciate this community.  I have made a few small (I'm low income) donations in the past.  If I do leave SC4 behind, I will always have fond memories of this place.

        After replacing my graphics card, I no longer see circles around effect tools such as god-mode leveling and smoothing. I have the latest driver, and my custom resolution works without a hitch. Only glitch I've noticed so far is that the area circles aren't there any more. Does anyone have any hints? Can anyone suggest the pertinent keywords for me to search old threads?

        Page headers - custom graphics - banners !
        City Journal series giving it a own identity a special page header to start and some kind of interuption between pictures and or some banner to close off, makes a CJ more elegant. Type faces, photo list´s, animated gif´s. Well done, this all can be easely added and adjusted to personal taste or events !
        Sincerely yours,
