Is there any way of changing minecraft fullscreen resolution, I know it can be done with optifine but optifine screws my minecraft running animation. I know pressing f11 to go into full screen sets minecraft to the resolution of your monitor but i want to play fullscreen with a lower resolution, is it possible? maybe there is a program or mod for that?
Can you not change your screen resolution manually before starting minecraft? I know video drivers often have software that sits in lower right corner, and allows you to change resolutions from a dropdown menu. Should be pretty easy.
