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