I thought most video cards came with a DVI-to-VGA adapter. Mine always have. Not that I expect you to go out and buy one if you weren't supplied with one along with the computer. Maybe they don't always supply them with newer cards.
You reminded me of a little bag of goodies that was left over after I got this computer hooked up two years ago; and, sure enough, there was a DVI-to-VGA adapter in there. I hooked up the 4:3 monitor to the GTS450, but the flickering was still there, exactly like on the widescreen monitor.
Yup. That's the problem with going back to older drivers from before the card was made. There IS a way to force an install of drivers that don't recognize a particular card by modifying the inf file of the drivers, but there's no guarantee those drivers would work properly with the much newer card. This is often done to adapt Nvidia drivers for laptops (***example***). However if the compatible drivers were for 32-bit Windows and you're currently using 64-bit, it might not work so well.
If I had known about that inf file trick 2 years ago when I was trying to find a solution to this problem, I might have tried it (the drivers that you found for me were listed as being Win7 64 bit compatible). But now, I have fixed the problem with the old refurbished Dell, which is running all 6 of those Kheops games perfectly. Best $100 I've spent in a long time. In addition to the Kheops games, I've got a handful of other old games working on it that wouldn't work on the Win7 computer. I just got finished playing Mystery Of The Druids, and I've also got running the DVD version of Traitor's Gate, and the DVD version of Dark Side Of The Moon, which up until 2 years ago wouldn't even work on XP, until Greyfuss found somebody who had got it to work. I've had that game for so long that I can't even remember where or when I bought it, and I've never played it.
I didn't really join in on this thread to try to find a solution to this problem. I only chimed in with my two cents worth to clear up an apparent misconception that this was a Windows 7 problem, although, I agree with you that anybody that's using an Nvidia card on Windows 7 is probably going to be stuck with drivers that are going to cause this problem, and the only known way to get around the problem is the "bFullScreen=0" workaround.
