Re: [Haskell-beginners] Performance problem with Haskell/OpenGL/GLFW

Okay, I think I just figured this out. Well, HOW to get it working with the accelerated renderer. I was wondering a simple way to check renderer info so I ran glxinfo. This (automatically) fired up X11, and then on a hunch I re-ran Test2 with X11 running and got this: hhmacbook:~/Development/haskell/OpenGL:57> ./Test2 hardware (2,7,7) (3,2,0) hhmacbook:~/Development/haskell/OpenGL:58> AH HA! I then quit X11 and re-ran Test2, and got this: hhmacbook:~/Development/haskell/OpenGL:58> ./Test2 software (2,7,7) (3,2,0) hhmacbook:~/Development/haskell/OpenGL:59> SO- If you want the accelerated renderer, you need to have X11 running. Now, I have no idea WHY this is the case, but there you go. Hope this helps. -Hollister On Mar 10, 2013, at 3:10 PM, Hollister Herhold wrote:

That's what I thought from looking at the output from dtruss.

Is this a GLFW-only issue? It seems unlikely that Haskell OpenGL apps in general have been using the software renderer.

Digging... Is that a configurable thing?

I just checked and it looks like it's at least trying to use the native framework.
