/*
From Ryan Gordon:
SDL's FULLSCREEN_DESKTOP mode on the mac now
puts the game in its own fullscreen Space on OS X 10.7 and later, as of
SDL 2.0.3, I think.
There were several benefits to this, but it's possible (likely even)
that Apple unhelpfully clamps you to vsync in this scenario, which would
explain the 60fps max.
There are a few options:
- SDL_WAINDOW_FULLSCREEN mode will not use this new magic (only
SDL_WINDOW_FULLSCREEN_DESKTOP), but that brings other problems and I
wouldn't recommend a drastic change like that.
- You can force the old behavior with this hint:
SDL_SetHint(SDL_HINT_VIDEO_MAC_FULLSCREEN_SPACES, "1");
...which must be called before SDL_Init(SDL_INIT_VIDEO) at the moment
(that can be changed if you'd like to add a menu option that wants to
toggle this setting at runtime, though). One can also force this with an
environment variable, for what that's worth to most Mac users:
export SDL_VIDEO_MAC_FULLSCREEN_SPACES=0
- I haven't tried it, but maybe one can force vsync off with
SDL_GL_SetSwapInterval(), and it's just that the default is different
for Fullscreen Spaces? Simplest solution if it works, but I don't know.
You can certainly just force it off to put the game back to the way it
worked before, but the user experience is much nicer when you can just
slide between the game and your desktop, etc. Discounting the clamp to
Vsync, we found that a Fullscreen Space got a slightly faster framerate,
too (plus it's how Apple "wants" you to do fullscreen at this point, etc).
And of course, this is Mac-specific: this is in the Cocoa backend, and
thus doesn't affect Windows or Linux, etc.
