Flash Performance Series: “Resolution & redraw regions”

Resolution & redraw regions:

Generally, the performance bog-downs in Flash are reduced to how much is being rendered at a specific moment, namely, what percentage of the screen is being redrawn. The larger the size of the screen, the larger the quantity of pixels that flash has to redraw each frame, so in all aspects, a 800×600 flash app will be slower than a smaller one.

Apart from this, the size of independant redraw regions will also influence the performance rates. This means that in some cases a complicated but small image(a small star or a drawing of a person) may be easier for flash to render than a much simpler but much larger shape ( maybe a square or rectangle). Also, rendering small things in the edges of the screen could potentially enlarge the general redraw region, giving flash more work to redraw a whole frame.

Because of these two things, it is always a good practice to keep both overall app. Resolution and redraw region sizes as small as possible, as well as trying to avoid animations & effects on the edges of the screen.
