Sim City Deluxe Edition Speed Corruption

[mrzeppelin09 4]

Hi, i'm running sim city deluxe with a NVIDIA GeForce 6150 LE, and somthing just isn't right. I've can play the game for about 30 minutes to an hour at the most, but afterwards the game will start taking radom speed "bursts" and the camera will not move properly. The game is playable, but this glitch is really annoying and more than I can cope with. I know I can go back a few drivers, but this makes my computerer slow and laggy. Any suggestions?

i know people are going to say "no don't do it" but try running in "software mode"... (switch in the game's graphic options)

its what i do and the game runs flawlessly

That didn't work

If you don't have a large amount to memory, then the game will go to the "virtual memory", and that is extremely slow.

My computer is barly loaded. Im  using nfts and have a clean os.

check your virus scanner... is it doing its thing?

or any other progs running in the background?

id say save when it happens... and reload the game....

maybe even check your temps and if you have the latest patch

mrzepplin, I am running with a GeForce 7600 GS and having a similar problem. This never happened before I reformated this computer and reinstalled the drivers, leading me to think that a newer driver for the card than I used to have may be a contributing factor.

The game time seems to be running normally, but the graphics become jerky and way too fast (e.g. smoke plumes flickering quickly, blinking lights stobing, etc.) I tried software mode without any result, so if anyone has any brilliant ideas I'd love to hear them.

Hmm, I also just realized that I've lost props on most buildings, but I have to assume that's from switching too many graphics settings too quickly. I didn't notice when it first happened, but I bet I can undo it. The city I'm testing with is far too small to have developed "prop pox" as it seems to be described elsewhere and I only have a few plugins installed (having just reinstalled the game). I will test further and maybe try a clean install since I have nothing to lose. I'll report back.

As I suspected the loss of props was just from a setting I hadn't noticed I had changed.

At this point I've tried removing all plugins and messing with all the in-game graphics options and nothing helps with the main problem. I strongly suspect it's something to do with my new Nvidia GeForce driver.

From the information I've gathered about it, is without a doubt the driver. i'm just looking for a fix, becuase my secondary,  14 year old computer computer with an ACP Video Card is failing horribly! ( The Motherborg needs replacing, DVD drive needs replacing, fan needs cleaning, etc.)

I just downloaded an old version of the driver from NVIDIA and it seems to have corrected my problem. You can try it using the NVIDIA site. Go to http://www.nvidia.com/Download/Find.aspx?lang=en-us or just go to the main driver site and click "beta and archived drivers."

Actually looks like I may have actually had a really old version of the driver instead of one that was too new, so maybe even downloading the latest one would work? I'm not sure.

My new driver helped but did not eliminate the problem, as it turned out. So I poked around here through old topics and found someone or other suggesting that the problem might be due to SC4 not being optimized for a dual-core processor, which I have. I opened Sim City, then hit ctrl-alt-del to get to processes and changed SC4 to be high priority and *set the affinity to just one processor core.* This seems to have finally fixed the problem, but only time will tell!

U a lifesaver broham. Just kidding, but thnks, that seems to have solved the problem.
