program usring SDL lib run at ARM board, show image speed is very slow.
i use SLD lib to develope a horse run game,at the beginning , i put program run on linux horst , it looks like a game.
then i let it run in arm 9315 board , show on TFT LCD.
screen shows five backgroud photos and five horses, horse run on backgroud.
each backgroud photo's size is 300kb . horse's size is 15kb.
of course arm performance is difference with PC .game Speed looks not very well .
to make backgroud more beatiful ,i add five photos ,each 300kb in backgroud.
all run slowly. then i make backgroud stop moving,they only show in the screen. but horse move slowly all the same. it seems have no realtionship with backgroud move or not, but have to do with photo numbers. of course arm performance is difference with PC .i have check
program , it seems that the photo number that screen once show make the problem. i'm chinese , wish you Happy Christmas.
