@Bts152 The game is using your Nvidia card, and rating it correctly (despite the fact that it's unrecognized), so that's not the issue. I understand that the screen filckers in fullscreen mode, but please try it and see whether you specifically get the same white lines or not. Even if fullscreen mode isn't a solution, it's still useful information.
Please also try playing in windowed mode at a resolution smaller than your screen, as in, something smaller along both dimensions than 1920x1080. Again, even if this isn't ideal, it's worth checking to see whether the lines are still there.
The reason I'm asking about fullscreen mode is that the flickering you've described can often be fixed by enabling vertical sync. While the v-sync option in the Nvidia Control Panel doesn't work anymore on laptops with dual cards, at least as far as I can tell, there is a tool that works for games that use DirectX 9, like Sims 3 does. Since it's a third-party download, I can't link it here, but if you're interested, let me know. Another player tested it a few weeks ago and reported that it worked well with Sims 3.
