Summary0004358: image_downsize causes text, map guis, hud icons, menus, and backgrounds to become blurry
DescriptionThe image_downsize cvar is used to improve performance and lower memory requirements at the expense of texture quality. Changing this value also unintentionally changes the texture quality of GUI interfaces.

This fix will address that.

Caveats: Lowering image_downsizelimit below 512 will cause parts or all of the scene to render when postprocess\bloom is enabled.
Steps To Reproduce1) Edit Darkmod.cfg

seta image_downsize "1"
seta image_downsizelimit "128"

2) Start TheDarkMod.exe
3) Note that the text and backgrounds are blurry. Note that map guis are unreadable.
Additional InformationThe fix is to create a blacklist in image_init.cpp

Example:

else if ( name.Find("fonts/") >= 0)
    {
    allowDownSize = false;
    }

The "fonts/" is part of the file-path to a font image. Anything with that same path will not be downsized.
TagsNo tags attached.
