Is that a Big Layout?

Is a layout with 1280, 720 pixel is considered a big layout? Cuz I don't want my new game to have low fps & slow. Thanks in advance

No, that isn't large at all. Are you talking layout (like level size) or viewport/window size?

One of my layout's is : 90,000 by 3000 px and every thing is fine.

r u talking about layout or window size ?

I consider a 1280x720 to be a rather small layout if the game has a camera that scrolls around. Perhaps, as the other 2 members already pointed out, you are referring to the window dimensions...?

C-7 & A0Nasser& eli0s Im reffering to the game's layout not the windows. Im afraid it will take too much memory

The layout size is just a number. The memory footprint is directly related with the objects that are loaded in each layout. Also, the cpu/gpu strain is being used only by the objects that are on screen or have some motion/opacity/rotation/etc change (and so those properties have to be calculated).

An empty layout of any size should not have any memory impact at all.
