I installed the new geforce drivers so I could do 4x DSR in world of warcraft (I need this now MSAA has been removed). This works well but I find now I cant get dosbox or scumm vm to run full screen with the correct aspect ratio (black bars on the sides). Now it will always stretch the image.

With dosbox I tricked it by telling setting the output to 4k and that works (i get the bars). But I cant do that with scumm vm because there is no resolution selection.

Has anyone else come across this problem?

I would guess that this is related to the new DSR AA modes. Those modes are more or less intended to stretch/reduce an image so the output resolution fits the display resolution. I'd guess that disabling DSR for DOSBox/Scumm would correct it. I can't confirm as my GeForce 580 doesn't support the feature.

I thought the same thing I unselected the default dsr 2 and 4 which changed the option to off. But the same thing happened. Maybe its my pc only, my google searches pull up nothing.

In DOSBox setting the resolution to 0x0 and aspect=true with opengl or openglnb should do the trick. Don't know about ScummVM.
