'Aspect=true' being incorrectly(?) applied to DOSBox shell in SVN r3925

Hey all, congratulations to the devs on such a fully featured and mature piece of software, especially considering some of the challenges you must face.

I recently upgraded from version 0.74 to the latest (as far as I can tell) dev build from EmuCR, r3925. As I use DOSBox with a lot of mode 13h games (Wolf3d, Doom etc.) I always use 'aspect=true' for them to display properly, I also launch DOSBox with commands in the autoexec to automount my DOS games folder and drop me into a fullscreen prompt in C:\.

In 0.74 on my 16:10 aspect monitor the prompt took up the entire screen and the letters were sharp, followed by the 320x200 game being correctly fitted into a 4:3 box with sidebars on launch. In r3925 with the same settings the prompt is now being (seemingly incorrectly) squashed into 4:3, with the text quality suffering as a result. 320x200 games launched are still rightly adjusted.

I was wondering if this was intended behaviour, or if there might be something wrong with my setup. I have an HD4870 with the latest Catalyst drivers installed and use them to enable GPU scaling if it helps.

Let me know if you need more info or if I've done fucked up somewhere. I can definitely recommend to anyone reading to try the latest builds as they fixed some quirky OpenGL errors I was having with 0.74.

Can you post your DOSbox config file, at least the first part that covers the graphical aspects.

Sure:

[sdl]
fullscreen=true
fulldouble=false
fullresolution=desktop
windowresolution=original
output=openglnb
autolock=false
sensitivity=200
waitonerror=true
priority=higher,normal
mapperfile=mapper-SVN.map
usescancodes=true

[dosbox]
language=
machine=svga_s3
captures=capture
memsize=32

[render]
frameskip=0
aspect=true
scaler=none

I did a bit more searching and came across this post by ripsaw8080 which is exactly the issue I'm having, except in fullscreen.

Aspect correction of text modes in SVN is deliberate. The choice used to be for sharper text; now its for more consistent output window size.

Thanks for the quick reply! I thought there may well be a reason for the change in behaviour and you explained it. I preferred the previous behaviour but I can always rollback to a previous version or try to tweak it myself.

Thanks again for the info and awesome program.

That looks fine. You can try

output=opengl

for a slightly softer look.

Another option is playing around with Dynamic Super Resolution, which will render the image at 4K and then downscale it. I found it works very well with low resolution text, especially ddraw, and openglnb can make text appear weird, with some lines being thinner than others.
