Yea, this is just from my recent experience messing with a game engine
in Haskell - I'm only a few months into it though.
So far, the GC hasn't been anywhere close to having a problem keeping up
with the monitors refresh rate. Even with several world states being
folded into a frame.
The memory usage is pretty flat too, at least with GLFW (the GLUT
bindings had some issues there iirc).
The test is pulling a pretty constant 1500 fps on this machine with the
background + 1 character running around and resources being streamed in
lazily. Not that that means much, but at the very least a GC run isn't
noticeable on the current data set.
Initially i expected this setup to perform badly, but i tried it anyway
out of curiosity. We'll see how it goes with full sets of data later i
