Basically, the problem is that when you turn on 5:4 correction, GZDoom squashes the display in the wrong direction, thus making the problem worse, instead of fixing it.


GZDoom, 720*576 (lowest 5:4 there is), no correction:

Turning on 5:4 correction.... [angry_nintendo_nerd]Well, that really accomplished a lot![/angry_nintendo_nerd]:

And there you have it.

Yes i also noticed this, ZDoom squeezes the image down, and shows a little more in the top and bottom, GZDoom stretches the image upwards making everything look too thin

will this need fixing in zdoom or is it a purely gzdoom thing?

It was a GZDoom only problem. The aspect ratio information for the software renderer was not suitable for OpenGL.

Glad to see you were able to fix it. Thanks a ton, Graf.

Strange that it would make it do that, though. Seems like it would just not do anything then, or garble the screen up... Heh, goes to show you how much I know about these things.

I have absolutely no idea how the software renderer is getting the correct ratio from the values stored for 5:4. In the end it was easiest for me to create a new table with the correct aspect ratios.
