choose refresh rate in fullscreen mode

Guest · Post by **Guest** » Sun Jan 04, 2004 12:35 am

is it possible to choose the refresh rate when initializing fullscreen mode
ex: 640X480 16bits 60Hz ?

Dont mess with this things, firstly you dont want to break someone's monitor, secondly not all videocards do that and thirdly DX doesn't allow this.

well, you're probably right
but if I make a very smooooth scrolling (ex: 1 pixel step), the real seed of the scrolling is different if you run à 60Hz or 85Hz (because Irrlicht waits for the VBL in fullscreen mode)
and that's a problem for me.

make some FPS-limit code, and make your game run at 60fps only, so you know it wohnt run faster
check out the article, it can give you some ideas:

I know but the scrolling won't be smooth any more
ex:

60Hz : Step of the scroll =1 (integer value) speed=60 pixel/s
(image moves every frame => smooth)

85Hz : Step becomes 60/85 = 0.706 (float value) speed=60 pixel/s also
but the image will NOT move every frame => NOT smooth

do you follow me?

hm, just make sure then it doesnt run faster than 60 fps and it will work out
