I just upgraded from ST3 to ST4 in Win 10.
Did a clean install - uninstalled all previous instances of ST3 and started fresh.
The font size is locked at 10px. None of the following work:
- Preferences.sublime-settings comments say:
// Note that the font_face and font_size are overridden in the platform
// specific settings file, for example, "Preferences (Linux).sublime-settings".
// Because of this, setting them here will have no effect: you must set them
// in your User File Preferences.
I looked for āPreferences (Windows).sublime-settingsā in all the directories.
Does it exist? Where? 
- Created file āC:\Program Files\Sublime Text\Packages\user\Preferences (Windows).sublime-settingsā anyway ā¦
Nothing.
-
Using CTRL+= command. No result
-
Setting font-face and font_size values in Preferences.sublime-settings (even though it says not to)
No result.
- CTRL + Scroll wheel = Fail
I hear ST4 uses GPU to render? Something to do with this feature? Can it be turned off?
Simple problem. Fonts are tiny. Squinting to see. Very annoying. Please help 
Youāre famous
