display_set_windows_alternate_sync(flag);
| Argument | Description |
|---|---|
| flag | Use an alternative method (true) or the regular method (false). |
Returns:N/A
This Windows only function can be used to change the vertical
synchronisation method at runtime. When set to true (and
you have vSync active) an alternative method will be used to that
which is the default, with the aim to reduce any possible visual
lag or stuttering of your game. Note that this can also be set in
the Global Game Settings and that it is only applicable Windows
7 and above - it will just use the default method if you have
this option ticked and run on XP or Vista - and that it does
not switch it on or off, for that you would use the function
display_reset().
if !display_get_windows_alternate_sync()
{
display_set_windows_alternate_sync(true);
}
The above code will check to see if the v-sync method is using the alternative or the default, and if it's the default it will switch to the alternative instead.
