The background Image.....

Load Bitmap " Your Background"

Does not slow the game down at all.

Lets see some code. Maybe theres something else you are doing that is slowing down the game. Loading a bitmap shouldnt slow the game down that much.

turn off the sprite backsave feature and repaste your background image each loop cycle.

are you using "SET SPRITE"?
set all of your sprites like this
SET SPRITE sprite_number,0,1

This turns off the sprites backsave feature which is nothing more then a get image command and is very slow. this speeds sprites up alot, really alot.

When you add a background just redraw it each loop cycle.

heres a example(untested but you'll get the idea.)
hope it helps, CTP

load image "background.bmp",1,1
load image "spriteimage.bmp",2,1
set sprite 1,0,1
do
paste image 1,0,0
if rightkey() then inc x,1
if leftkey() then dec x,1
if upkey() then dec y,1
if downkey then inc y,1
sprite 1,x,y,2
loop

If you don't understand set sprite, then maybe you should be reading up a bit on it in the manual... It's a very important concept if you are going to make anything 2D in DB...
