Re: [Haskell-cafe] threadDelay granularity

I think this is an RTS option. http://www.haskell.org/ghc/docs/latest/html/users_guide/using-concurrent.htm... On Tue, Apr 7, 2009 at 1:41 PM, Ulrik Rasmussen wrote:

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:

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,
