Do you want to cap the rendering framerate at 60FPS or the animation
framerate?
Because when you use OpenGL and GLFW, you can just
GLFW.swapInterval $= 1
to cap the rendering framerate at the refresh rate of your monitor or LCD
screen (usually 60Hz)

Hello.
I am writing a simple game in Haskell as an exercise, and in the rendering loop I want to cap the framerate to 60fps. I had planned to do this with GHC.Conc.threadDelay, but looking at it's documentation, I discovered that it can only delay the thread in time spans that are multiples of 20ms:
http://www.haskell.org/ghc/docs/6.4/html/libraries/base/Control.Concurrent.h...
I need a much finer granularity than that, so I wondered if it is possible to either get a higher resolution for threadDelay, or if there is an alternative to threadDelay?
I noticed that the SDL library includes the function "delay", which indeed works with a resolution down to one millisecond. However, since I'm using HOpenGL and GLUT, I think it would be a little overkill to depend on SDL just for this :).
Thanks,
