NVidia Optimus (GTX00M) Cannot Run in Fullscreen Mode

Heya everyone,

Thank you all for for posting your DxDiag reports. The studio had one internal repro where this issue had been caused by setting the DPI settings within Windows higher than the default one.

As a result, the window size of the screen will be improperly calculated and causes an infinite flickering between windowed and fullscreen.

Have any of you also increased the DPI settings? If so, what happens if you rever it back to 100%?

Within Windows 7, the specific setting can be found here: Control Panel -> Appear and Personalization -> Display -> Zoom

I am especially looking at you @FlakRat @Laipro @dilem54  as your DxDiag does indicate that you did have this turned on.

AJLeuer within this thread has also indicated an issue with the scaling here, as confirmed by Damark1981.

Thanks a lot for your replies in advance,

Nils
