They're pretty short, but >are they short enough for high-performance video game stuff ? Not sure yet, since I haven't written a large program yet. It looks like the Gc module gives you some control over this? How bad does it get in real-sized apps? A short pause is not bad if I can control when it happens (level load time, etc.). >> 699000 >Where did you get that number from ? Oops, sorry, that was (Sys.max_array_length / 2) / 3 for 3D vectors, I forgot that I'd divided by 3. Anyway, what's the nature of the limitation? That is, why can't I have an array the size of memory? I assume you're using bits in the index or the pointer or something? Any ideas as to how hard it would be to recompile the compiler to generate 32bit floats? Chris
