Hi,

I'm doing something very simple, rotating a textured sphere on the screen, but the framereates are killing me!
Am I doing something wrong here?

+ Code Snippet

sync off
sync rate 0
backdrop on
load object "sphere2.x",1
load image "water2.bmp",1
set object texture 1,2,0
texture object 1,1
ycoord# = 10.0
xcoord# = 10.0
repeat
  rotate object 1,0,xcoord# ,0
  ycoord# = ycoord# + 1.0
  xcoord# = xcoord# + 1.0
  if upkey()=1 then move camera 1
  if downkey()=1 then move camera -1
  fps$="DBPro Fps: "+str$(screen fps())
  text screen width()-20-text width(fps$),screen height()-40,fps$
  sync
until escapekey() = 1

Can't understand...when I run the same code in windowed mode, it runs around 200 FPS.

My hardware : GeForce2(Anihhilator Pro) 32MB
1Ghz Athlon ThunderBird
256MB RAM
to my knowledge, this should FLY!

Thanks

I think the problem is that in windowed mode it makes a window that is 640x480 pixels and runs the game normally, but if your screen mode is set to 800x600 or 1024x768 then in fullscreen mode it has to scale each pixel so it fits the entire screen perfectly, slowing it down...the best way to fix this would be to set your display mode to 640x480 or to use the command {Set Display Mode ScreenHeight#,ScreenWidth#,ColorDeapth#} and set all the values to the current window mode...well...i hope this helps...
