Re: Uneven V-sync

Hello everybody,

since I am the one who has raised the subject, I allow myself to preside once again on my question:

As I understand, what VSYNC does in background is much more complex than simply waiting for retrace. Probably VSYNC does work correct in my case, because I do not have any problems with tearing screens. I actually do have a problem with uneven duration of iterations and with jerking Scrolling in result. 

Till now I thought VSYNC would lead to regular iterations. On Android this is apparently not the case, so far I can see. But with iteration time of 45ms one or two times in a second, smooth movement isn't possible. And reducing the framerate to 45ms in general isn't a solution either, because then everything jerks all the time. 


So here is my precised question:
Is there a way to prevent foreign Android processes from stealing SDL or my program to much time?


Thanx in advance, Michael
