I've added a VAO and reduced the inner loop to only a call to glDrawArrays which renders 8000 triangles (24000 vertices). The gameFrame function now benchmarks at ~86ms on my machine. I would expect it to be ~16ms because of vsync. I've pared down the entire project into this buildable cabal project of three files, most of which is OpenGL boilerplate: https://github.com/MichaelBaker/haskell-opengl.

Awesome. Thanks! I'm taking a look now. I'll let you know if I figure out anything.

I only have access to windows at the moment and I'm getting a weird linker error in bindings-GLFW when trying to build GLFW-b: Loading package bindings-GLFW-3.0.3.2 ... linking ... ghc.exe: unable to load package `bindings-GLFW-3.0.3.2' ghc.exe: warning: _vsnprintf from msvcrt is linked instead of __imp__vsnprintf ghc.exe: C:\Users\dagit\Documents\Repos\haskell-opengl\.cabal-sandbox\x86_64-windows-ghc-7.8.2\bindings-GLFW-3.0.3.2\HSbindings-GLFW-3.0.3.2.o: unknown symbol `strdup' Failed to install GLFW-b-1.4.6 I'll try on osx tomorrow.
