May be a dumb question...

How do you change the default display resolution screen that comes up when you start a build? I do not know where to access it.

Thanks, I just couldn't find it in the manual....

Except, you may want to keep the aspect ratio the same for normal and fullscreen views. 512/320 represents the "widescreen" aspect ratio that modern monitors use. 1024/768 does not, so if you elected to keep a certain aspect ratio for the game, someone with a 1280 x 800 screen, for example, would only get to use 1024 x 640. This is not important if you disable fullscreen, but otherwise, it matters.

My games have so far been simple enough that I have used 2560 x 1600 for the max res (Default Screen width/height). That covers the largest display that anyone is likely to be using (30"), and anyone with less than than will just get to play at the maximum resolution their monitor supports. For more demanding material, you might want to cap the whole thing somewhere lower.
