OK, folks, after more than a decade absence, I decided that it was time to play Sims2 again. My old installers didn't work under W10, so I downloaded the Ultimate collection from Oldgamesdownload.
Now I ran into a few problems. The game starts in 800x600, since it doesn't recognize my card. So I tried to change resolution as described in here.

Only rolling back to the old Graphics Rules.sgr fixes that, but at the cost of the ultra low resolution.
Anyone ran into similar problems and has a fix?
Edit: Solved. Well, kind of. The solution lies in windowed mode. I still can't run it in fullscreen.
