Open Windows Settings > System > Display > Graphics settings, click Browse, find TS4_x64 on the list, and choose the power-saving option. Then right-click the desktop, choose the Nvidia Control Panel, click Manage 3D Settings > Program Settings, find TS4_x64, and choose the integrated graphics processor. Both these settings matter at least some of the time.
The idea is to see whether the game works fine with the Nvidia GPU out of the picture, which would confirm, at least as far as we can do here, that the Nvidia GPU is the issue.
