AMD Radeon HD 6670
hello again! sorry for the delay. i think this will fix your problem: http://www.abvent.com/support/faq/1606-how-to-change-graphics-card-settings-to-use-your-dedicated-gpu-with-artlantis-on-windows-computer.html. you'd want to follow steps 1-4, and then 8-9. then, launch "A Night Alone". at the start screen you can move the joystick left and right/press A and D on the keyboard. if you do and you can still see the graphics, just in a different color, then it was successful. if it still doesn't work, then i'll make a special version of the game that should work for you and send that over.
