LÖVE

I see that love.graphics.setMode is now love.windows.setMode in 0.9.0

Is there any way to utilize any computer's full size of the screen but without the flash?

You can try using the "desktop"-fullscreen mode. See on the wiki. This makes the LÖVE window the size of the current desktop and removes the window frame.

There's also this now http://www.love2d.org/wiki/love.window. ... Dimensions

The flash? Of not switching window size after having created one? Well, don't create a window, as before. Set t.window to nil in love.conf.

Thanks Bartbes, I think that will be the ticket.
