The game works in all three modes.(window, window without frame, window in fullscreen), Except for fullscreen mode. When you try to switch to full-screen mode, the game goes to full-screen mode for a split second, and then returns to the one that was set before. Fullscreen mode starts working if the integrated video card is disabled in the device manager(Intel HD graphics 530) or if you turn on the PC in safe mode. Playing in the "full screen window" is unbearable because of low FPS. Laptop Asus ROG GL552VW(2 videocards: Intel HD graphics 530 и Nvidia Geforce GTX 960M) Windows 10 x64 All drivers are updated The game starts with a discrete graphics card Nvidia(everything is set up correctly in the nvidia control panel) There is no such problem with any other game.
