Freeze When Window Mode Selected

[The_Duluthian]

Whenever I select the window mode option in the setting menu, the whole game (except for the cursor) freezes. The same happens for Napoleon as well. Is there a way to fix this?

What GPU does the game use with and without Window Mode?

If you don't know, run Task Manager on the More Details -> Performance tab before starting the game, and inspect the display after closing the game.

I suspect that a low-performance GPU is being selected for use in mal-performing modes. This affinity can now be set per executable file in Settings.
