Last night I recently began having a rather odd issue with the graphics in my games. When I enter neighborhood screen or lots, the graphics "flash" in and out for lack of a better term, and also become weirdly pixelated. In the neighborhood screen they will look ok until I move the camera or the mouse, after that they flicker in and out between being correct and pixelated with evey mouse or camera move. The same thing happens on lots.
Here are some pictures that hopefully clarify what is going on. I apologize for the size, but any smaller and the issue is hard to see. In the second picture the glitch is hard to make out, but the whole lot is basically as pixelated and flashy as Pascal's head.
This just started last night totally out of the blue. I had the issue once before while running a screen capture program at the same time as Sims 2, when I removed it the issue resolved, and it didn't happen every time, only once in a while. As of now I am not running anything besides Sims 2, and have closed all background tasks before running, even my antivirus program. I've also tried it with and without Gunmods camera mod, which I've had forever, and with and without his lighting mod. Have loaded the game with and without all my custom content as well makes no difference. I thought it may have been an overheating issue, so I tried again this morning, after leaving the computer off all night, still no luck.
My graphics card is an Nvidia GEforce 7300 ( I know the evil, but the computer was all I could afford, and until now I've had no issues, no bluscreen of doom nothing) I am also running Windows Vista. Prior to the graphics glitches I had done nothing, hadn't installed any new graphics drivers or expansions. The only thing I did was restore Strangetown to my neighborhoods from the backup in the game files. Last night after the graphics weirdness I updated my drivers, but not a thing changed.
Thanks in advance for any help you can provide. Sorry the post was longwinded, but I figured the more details the more likely someone would have some idea what went wrong. Thanks again for reading.
